Review – Challenge Limus Team Edition S 33mm Cyclocross Tubulars

In short: When Pros are putting in special requests for unbranded Limus’ on the muddiest of days it’s no wonder we found the Limus excelled in the muddiest of conditions.

With the wet weather finally arriving, mud is now expected for the majority of the remaining CX season. This means riders will be looking to maximise traction on the bike in order to minimise time spent off it, therefore aggressively treaded mud tyres, like the Challenge Limus will be the most common selection for the Pro riders.

The Challenge Limus tyre has been around for a fair few years now, however we were lucky enough to get our hands on the brand new Team Edition S3 model to put it through its paces.

Review - Challenge Limus Team Edition S 33mm Cyclocross Tubulars

The first thing to mention is that all of Challenges tubular selection are available in open tubular models too. These can be mounted to a standard clincher rim and can provide excellent ride feel, speed and traction compared to a standard clincher tyre. Of the big 3 tyre manufacturers: Dugast, FMB and Challenge, it is only currently Challenge who offer open tubular models – therefore allowing those riders who still run clincher setups to use quality CX tyres.

The Dugast Rhino has long been the favourite choice for the Pro’s, however in recent years the Limus model has becoming increasingly popular. We’ve seen Sven and Thibau Nys riding Challenge, amongst other big name riders.

What really caught our eye though was at this years super muddy World Championships in Valkenberg 3 out of the 5 races were won by riders on the Limus and we even heard rumours of a certain Mathieu Van der Poel having requested a special delivery of Limus tyres for the big event!

Poor Quality – but that’s certainly a Limus tread on Van der Poel’s Canyon

The first impressions of mounting the tyre onto our test rims clearly showed the severity of the Limus’ aggressive tread. It’s not always you have sore hands having mounted tubulars, however I guess it could be a good thing showing us just how much grip the tyres have! The process was also made much easier thanks to the Team Editions new softer sidewall, featuring 320 threads per inch allowing the tyre to comfortably roll onto our test rim.

The new sidewall also offers additional protection from wear and tear thanks to Challenges new factory installed protective layer, helping increase durability and keeping those cotton sidewalls looking clean after some muddy races!

The new sidewall technology also offers a significant improvement in performance, especially when run at lower pressures. Challenge recommends PSI of 23-90 for the Limus, however as most cross riders know riders opt for the bare minimum when it comes to tyre pressure in the mud, in order to maximise grip, and we got our test pair down to as low as 16 PSI without issue (60kg test rider).

The ride feel at lower pressures was also a noticeable difference, thanks to the corespun sealed sidewall and 320 TPI the tyre behaved predictably at these lower pressures eliminating the feeling the tyre may roll off the rim in the corners.

Although the Limus does feature a super aggressive tread, which does roll slightly slower than the Grifo model (designed for faster grassy courses) a Latex inner tube helps reduce rolling resistance and allows speed to be maintained in the straights.

The Limus features one of the deepest treads on the market which allowed us to survive longer without the tyres clogging up with mud compared to other brands, whilst also being able to dig deeper into the soft stuff to provide traction when in other circumstances the wheel may have spun out.

The Limus tread is somewhat more different to the likes of FMB’s Super Mud offering, however with all the recent success of riders on Challenges’ Limus, time will tell if other brands follow Challenges lead with re-engineered mud treads.

Mid Term Review: Forme Calver SLC Carbon Cyclocross Bike

Thanks to Cadence Images for the photography, and VOID for providing us with some lovely kit for the photos

At the start of the season we were lucky enough to receive a brand new Forme Calver SLC Crossbike to test out for the season. After some early season racing here are our first impressions:

“Having only ridden high-end cantilever cross bikes prior to this season, I was excited to test out this new offering from Forme.

This is Forme’s high end Carbon Disc Brake CX race machine fully kitted out for the serious racer with Shimano’s new Dura Ace Di2 9170 Hydraulic Groupset, and as ridden by multiple British CX Champion Ian Field and his Neon Velo teammates.

Our build came as a full bike, however a frameset only option is available, to suit cross racer’s preferences and budget.

Immediately the lightweight setup provided super straight line acceleration, whilst the stiff bottom bracket and laterally stiff rear triangle seemed to deliver all the power to the rear wheel. I first rode this at the National Trophy at Derby, surprising myself by leading out the race from the gun taking the holeshot. The main frame angles seem race oriented, in particular the front fork allowed me to keep the ride aggressive in the corners and the longish wheelbase on the 56 cm frame meant I could keep things stable at speed.

This bike came with a tubeless set up which needs some practice to get right, riding very differently to tubulars I recommend giving the tyre pressures plenty of practice before race day to avoid mishaps. That said the Mavic Ksyrium wheels are strong and light, and could cope with everything I threw at them!

Thanks to Forme’s updated geometry the ride inspires confidence and the bike feels bombproof, which is just what you need if you are hopping the hurdles in a race or tackling dry ruts and bumpy fields at speed.

While I have yet to ride the frame in the mud, the clearance looks to be good with a high seat stay bridge and thin seat stays which seem to offer a good soft ride with vertical compliance given the stiffness mentioned earlier.

Other areas of notice included the through axles keeping things stiff at the rear end of the bike, as well as helping with tracking the front end and obviously the added security of having your wheels securely locked into the frameset. In addition to this, as expected on a race ready frame, internal cable routing helps improve durability and provides a clean finish to the Frame.

It is evident that Forme have put extensive time and effort into the design of this bike, with the top tube shape allowing for easier shouldering and most importantly the bottom bracket is threaded meaning there is no creaking, maintenance is easy and there is increase compliance in the BB area.

As expected the Di2 has been faultless and the frameset gives me every confidence it can tackle a heavy winter ahead with ease”

First Look: Van der Poel’s Secret to Success? 4Gold Nutrition

Mathieu Van der Poel and Gold. Two things commonly associated. Van der Poel does not settle for silver and neither do 4Gold who’s unique brand motto is #DontSettleForSilver

We were contacted through our website a few weeks ago by a Belgian CX Fan, who looked to share with us his reason why he thought Van der Poel had been so dominant this year in Cyclocross.

The margins between winning and losing in sport are often very small, and hence riders look for every marginal gain to increase their performance.

We were pointed in the way of, a new nutrition company, with great experience.

It turns out Ex-Pro Brent Luyckx and former motocross rider Axel Roelants joined forces with Mathieu Van der Poel to create a high-quality sports drink and nutritional range, which launched this season.

We’ve all heard of MVDP, however it is too Brent and Axel who bring great knowledge to the brand. Luyckx, not so long ago, was a very promising rider himself, together with ex-motocrosser Roelants and cross phenomenon Mathieu Van der Poel seem to have formed the perfect combination. “After more than a year and a half of long days and short nights it is finally, Mathieu Van der Poel, Axel Roelants and I who proudly introduce our food supplement company 4Gold.” explained Luyckx.

Luyckx, who is only 23, was forced to end his career early caused by Crohn’s disease, which affected his intestines. This motivated Brent to strive for the perfect sports nutrition: “During my career, I felt that there was still a lot of improvement in terms of supplementation, so the idea of ​​4Gold has grown to where we are now, namely helping with achieving the dreams of other athletes.”

There is already a wide range of products available specifically for a cyclocross rider. The range includes Pre and Post race drinks as well as Carbo Electrolyte drinks for which maybe were found in the bottle of Mathieu during the early season races!?

A further range is in development with additional energy bars and supplements, and recently a range of special performance coffee has been added to give you that extra recovery benefit.

As a team of professional athletes 4Gold were quick to realise that there are lots of different factors which determine what of, and how much you need to consume. As a result, thanks to extensive research and testing a table can be found on their website suggesting exact qualities and quantities of each product to be consumed depending on your own unique circumstances, such as your type of sport, your height, temperature etc.

And obviously with the extensive drug testing top riders such as Mathieu are subject to, the focus on drug-free food is also present, with products batch tested and batch numbers of purchased products available with information on the site.

Review – Challenge Grifo Team Edition S 33mm Cyclocross Tubulars

In short: Excellent all round CX tubulars with the proven Grifo Tread, a super soft sidewall, 320TPI casing and a new factory installed sidewall protection.

With us now entering November, and the course conditions softening up, the pros hang up their file-treads and opt for the Grifo Style Pattern.

We glued up a set of Challenge Grifo Team Edition S 33mm Cyclocross Tubular Tyres to see for ourselves why so many athletes are opting for the Grifo as an all round tyre.

First impressions of the new Team Edition S3 super soft sidewall were impressive, with the supple sidewall allowing for the tyres to easily be mounted to our test rims.

The new sidewall also offers additional protection from wear and tear with a new factory installed protective layer, preventing the sidewalls from rotting as fast increasing the tyres durability. That being said, the team edition cotton sidewalls won’t last as well as the basic ‘Grifo Pro’ Model which features a cheaper, less subtle, 300 TPI Super Polly casing compared to the Team Editions 320 TPI Corespun Sealed sidewall.

The new Team Edition sidewall offers a noticeable improvement in performance and feel, compared to the cheaper Grifo Pro Model, however we found the cheaper model to be slightly more durable. That being said, when compared to other big brands the Challenge Range offers excellent durability in comparison and the Team Edition S will still be going strong after a seasons use.

Another benefit of the high TPI (threads per inch) count offered by Challenge is that the feeling of the tyre rolling underneath you in the corners when run at low pressures is almost eliminated. This allowed us to corner at greater speed thanks to a more predictable ride feel.

Challenge sticks with the traditional proven Grifo Tread which offers a combination of different size knobs to allow for low rolling resistance whilst providing traction in the faster corners. The tyres also feature a latex inner tube sewn by hand into the tubulars in Challenges Italian Factory. This combination provides excellent all round speed for the faster grassier courses. The Grifo tread pattern clears mud very well so is also suitable for slippy conditions when others treads may begin to clog up, although if you are looking for something with a more aggressive tread for those really muddy days you should opt for the Limus model, which was ridden to multiple victories in Valkenberg earlier this year at the World Championships.

The main reason why we preferred the Grifo to its rivals such as the Dugast Typhoon and FMB Sprint is the additional side knobs on the very edge of the tyre. We found these provided extra traction when the bike was lent over in the turns and didn’t cost us any straight line speed. This allowed us to still be able to run our intermediate ‘all round’ Grifo tyres on days other racers had to bring out the mud tubs.

Finally all Challenge Tyres are also available as Open Tubulars which fit on a standard clincher rim. This allows you to run both the same treads on training and race wheels, and although tubulars for cyclocross provide a massive benefit compared to a clincher tyre, the new Clincher Pro series paired with a Challenge Latex CX Tube helped us bridge the gap in performance between a tubular and clincher setup.

Spotted: Prototype Tread from Challenge Tires

With the National Championship weekend only 10 days away, many riders are going to great measures to have the best shot of the National Title.

With the Belgian Championships being hosted in the iconic dunes of Koksijde, it’s no surprise the Belgians are looking for their file treads, whilst most of us other racers, their extreme Mud tubulars – two complete different ends of the spectrum!

European U23 Champion Eli Iserbyt posted this photo earlier on Instagram, of what looks to be a 33mm Road Tread! This looks similar to the current Dune offering from Challenge, but with an even smaller tread pattern, missing the smaller side knobs. Only on a course such as Koksijde is a tyre like this needed, with riders looking for the smoothest way through the deep sand…

We’ve recently seen Wout Van Aert using some interesting custom tubular setups – it will be interested to see what he opts for next weekend. To read our chat with Wout’s tyre producer Dugast about his custom treads click here

New Year, New Tech, Teams and More!

The New Years Day DVV Trophy round in Baal today was the first opportunity to see the new colours, bikes, buses and more in the Cyclocross Field…

Here we run you through all the changes and what you can expect to see in 2018:

Firstly Mathieu Van der Poel and his Beobank-Corendon team now have a new name, kit, bike and sponsor! Circus Casinos have replaced Beobank, with the team now known as Corendon-Circus. The new sponsor only meant one thing a new jersey, as seen below.

Along with a new title sponsor, Circus, Canyon Bicycles also joined as bike sponsor, replacing Stevens after a lengthy deal. The team will be riding the new Canyon Inflite CF SLX, with more details found here

Van Der Poel Canyon Inflite CF SLX

Mathieu and his team were also spotted wearing the new Lazer Bullet Aerohelmet, replacing the ever-popular Lazer Z1 – it looks like aerohelmets in cross are here to stay!

Also spotted rocking the new lids were Kevin Pauwels and his Marlux teammates, seemingly switching to the aero design from longtime sponsor eKoi. The main thing you would have noticed however is the new jersey for team Marlux-Bingoal, with Bingoal replacing Napoleon-Games as title sponsor

The super successful development team Lares-Doltcini also sees change, with Callant replacing Doltcini as title sponsor.

There was no change for World Champ Wout Van Aert, however it is rumoured Stevens could be replacing Felt as bike sponsor from 1st March, with riders reportedly unhappy with the current Felt Bikes. Van Aert’s teammates do see change however, with the Crelan Charles team changing kit to a more ‘striking’ green design!

There we no apparent changes for Vastgoedservice-Pauwels Sauzen, however a new team bus awaited the riders today in Baal! Would you like to see some team bus and truck tours next year?!

Team IKO-Beobank also had a new team bus – with Lotto Soudal reportedly gifting them this beast of a truck for the riders to use for the remainder of the season and beyond after the previous bus caught fire!

Photo credit: Radio2be


Sanne Cant remained on Stevens Bikes today, however new teammate Ceylin Alvarado was sporting the new Canyon

Talking of transfers, the Womens Scene has seen a lot of change. Firstly Helen Wyman will now be riding for new team/project Xypex-Verge Sport and will be riding KindHuman Bikes, after losing backing from long term partner Kona

Fellow Brit Nikki Brammeier also starts her own CX ‘project’ and will be another rider on Canyon Bikes as part of the Mudiita Canyon setup.

2016 World Champion Thalita de Jong also has a new team, moving from Lares Waowdeals to Experza-Footlogix for 2018 and is rumoured to be making her CX comeback next weekend in Lueven.

Review – Suplest Edge/3 Pro Cyclocross Shoes

As the cross season beckons we take the chance to review our first Cyclocross specific product of the season – the Edge Pro 3 Shoes from Swiss Shoe Company Suplest.

Suplest pride themselves as the smallest premium cycling shoe brand on earth, yet strive to create the best performing shoes both through comfort and functionality…

The first thing to note was the price, €349 / £300 seems expensive for a pair of shoes, yet when compared to other high performance rivals the price seems on par for a ‘top of the range’ shoe and it is fair to say we felt we got what we paid for with the  Edge/3 Pro shoes from Suplest!

Delivery was fast, and with a range of worldwide dealers, as well as a web shop ( ) the shoes are available across the globe and the shoes came professionally packaged.

Also included in the box was a nice Suplest Shoe bag for transport, as well as a range of studs for when the conditions turn slippy.

A stud spanner was also included which is a nice touch, however we left our test pair studless once we saw the impressive underside of the shoe, providing incredible grip even in the muddiest of conditions.

Sizing is something always debated on when purchasing a new pair of shoes, and having previously used an EU44 with both Specialized and Sidi, the 44 had a perfect fit and thanks to the closure system from Boa, we were able to obtain a snug fit in both thin summer, and thick winter socks.

The Boa dials make sure your feet are locked firmly in the shoes, and the new pull up to quick release feature came in handy when muddy hands were unable to grip the dials – a common problem with many other shoes on the market.

Structurally the shoes were extremely strong, with a unique micro-fibre material providing plenty of protection from the elements, whilst flex for running, yet the power transfer felt excellent through our small SPD cleats. The shoes weight in at a mere 330g (EU42) significantly less than other competition.

Overall we have been extremely pleased with the Edge/3 Pro from Suplest, and when compared to our previous pairs of Sidi and Specialized S-Works shoes would consider these a more than worthy upgrade. Afterall Suplest only create Cycling Shoes and strive to do so at the highest level – we feel this has definitely been achieved with the Edge/3 Pro!


Sizes:  EU 39-47 including 42.5, 43.5, 44.5

Colours: Black/Red or White/Fluro

Compatibility: SPD, Look, Time and Crankbrothers
