Ben Sumner CX World Championship U23 Specialized Crux Carbon (1)

Imagine taking the overall win for the National Trophy series, winning bronze at the National Championships, and getting to toe the line with the world’s best next month in Hoogerheide, Holland. Now imagine all of that before you’re even 23 years old. That’s the case with the UK’s Ben Sumner as he finishes up a great season on the cross bike and prepares for one final race which just happens to be the biggest one of all. Ben sent over some photos of his dialed ride for the big race that is decked out with some killer parts from his sponsors including Beeline Bicycles, Reynolds Wheels, Upgrade Bikes, Challenge Tires, Specialized UK, and Shimano/Mike Brunson. The full bike is said to weigh just 7kg (15.43lbs).

Details on the build for its World’s debut after the break.

Shimano Di2 electronic gearing has worked faultlessly all year despite the constant pressure washing and mud. The bikes show some battle scars but have held up well to the battering that a Cyclocross season dishes out. Shimano Ultegra ‘cross ratio cranks are a super slick edition.

Ben has been riding canti brakes this year and the fuss of adjustment and set-up has been taken away by the CX70 Shimano set-up. Great brakes. With disc brakes still limited by wheel choice canti brakes were the only choice for this season.

Using a £4000 pair of wheels off road?? Go on then… Proof that well built light wheels are also tough enough to rely on. Reynolds stand by the quality of their wheels and Ben has been a big fan for ages now!

Challenge tyres are winning some real fans on the ‘cross scene. It’s nice to see a company challenging ‘excuse the pun’ the reference Dugast tubulars and making Dugast riders question if they’re on the best setup!

Yeah for canti’s!

Sick bike. I’m digging that “nuovo murder” aesthetic – matte black with small splashes of color.

My favorite paint scheme from the big S right now.

patrik - 01/23/14 - 12:03pm

I hear the Big S is suing TAFKAP for his use of purple in ‘Purple Rain’.

Ripnshread - 01/23/14 - 12:17pm

Now lets see his sponsors step up and get him a fresh rig for the WC.

Eyal - 01/23/14 - 12:29pm

Wait no discs, this bike is invalid, this rider is incapable of stopping, and is in need of modulation or something like that. In the corners he will just crash, his brakes will lock up in the wet descents, wait, there are no descents in CX… blah blah.

LP - 01/23/14 - 12:30pm

Nice bike. I prefer straight top tubes….

fIsho - 01/23/14 - 12:46pm

Tron wants it’s paint scheme back.

uglyyeti - 01/23/14 - 12:48pm

I’m sure someone will come up with a conversion contraption so he can run hydro levers with his cantis.

Seraph - 01/23/14 - 2:24pm

Puke city. What happened to coordinated color schemes? This isn’t the mid-90s.

wheelguy - 01/23/14 - 2:30pm

I have the same frame. Happen to love the color scheme (obv since I bought it), but realize it’s not everybody’s cup of tea. Was just so tired of same old black, red, white…

jaas - 01/23/14 - 3:35pm

you people could be given a bar of gold and you’d still hate it if it said specialized on it.

uglyyeti - 01/23/14 - 4:03pm

@jaas – If you have a bar of gold with Specialized printed on it, you’d better hide it before their lawyers find out.

jaas - 01/23/14 - 7:03pm

@uglyyeti well played

BEERTECH - 01/23/14 - 7:38pm

I love the colorway. Nice rig.

wan - 01/23/14 - 8:08pm

aaand, nobody mentioned the colorway was designed by Garret Chow? :/

muf - 01/24/14 - 12:49am

i like the colors too. unfortunately not enough money for it, but i like the frame, so i got the standard colors 😉

Aaron Alter - 01/24/14 - 11:57am

I set that frame up for one of our race team guys. We converted a set of Specialized Roval Carbon Control 29er wheels to 11 speed with a DT 11 speed freehub. Bike is equipped with SRAM red 11. Disc brake, Tubeless capability, and mtb tough. Should be everyones next upgrade.

Aaron - 01/24/14 - 12:05pm

I built one of these up for one of our race team guys. We, (Jas and I) coverted a set of ROVAL CONTROL 29 CARBON wheels to 11 speed with a Specialized/DT 11 speed freehub body. Disc brake, tubeless capability, & MTB tough. Should be everyone’s next upgrade.

muf - 01/25/14 - 12:28am

mine is tubeless as well and i don’t understand the “tubular or nothing” and “tubeless burp” issue. ive no burp even if im way under the pressure i’d run.
