We’re just off the phone with Nuke Proof’s top design whizz, who gave us the low down on this innovative new 4X bike that’ll be piloted by Lukas Mechura on the World Cup circuit. Lukas rode for Team Chain Reaction Cycles last year (where he podiumed at Fort William) and this year will ride for Team CRC/Nuke Proof.
Lukas is a big lad at over six foot, so his signature frame comes in XL and it has been built to be a Four Cross bike first, rather than being an adapted dirt jump bike. This means the frame is longer than a dirt jump bike for better stability on the 4X courses. To cope with the immense pedalling forces going through the bike, it comes with a 135mm Maxle back end to match the short travel 80mm Fox 831s up front. At the head tube end, there is the new 44mm internal diameter oversize headtube – this means that it can take 1 1/8th internal, or external cups, or a 1.5in external lower cup, with a regular 1 1/8th internal top cup. (This proto has a regular 1.5in headtube.)
There will be a production version available in September – or rather two of them:
One will be as you see here, in a 135mm Maxle rear – in Small, Med/Large and Xtra Lukas sizes.
There will also be a version with replaceable dropouts, allowing rear QR, rear 135mm Maxle or the new Syntace 142mm bolt-thru dropouts.
Other clever features include the downtube logos being printed on the underside of helicopter tape. (So re-taping a scuffed up frame gives you new decals at the same time), the frame will take 2.5in tyres and has ISCG mounts as standard, with no provision for a front mech. As well as Team Issue Yellow, it’ll come in black and Spangle Black too…
Number fans take note: 67.5° head tube angle, static with an 80mm fork. And the price for the frame? “Under £300” according to early calculations…
