Utilising strengthened versions of all the components on our K142TL wheelset, including being built with incredibly strong hubs and 32x3cross spokes per wheel - This is a super-aero road/TT/Tri wheelset aimed specifically at heavier riders.
Features a superb new wider rim profile compatible with both clincher and tubeless tyres and designed to be so strong it can even be used on tandems. Slightly wider rims are the future of road wheels. They enable seamless tyre interfaces for max aero gain, they allow for wider tyres for shorter 'contact patch' and less rolling resistance. Superbly aero and comfortable too - they will take a tyre from 25c up to 40c width!
Offered With Full Warranty Plus A 14 Day "No Quibble Returns Policy" - If You're Not In Love With These Wheels The Moment You Get Them Just Send Them Back For A Refund Any Time Within 14 Days Of Receipt.
The balance in the rim is fabulous - and from a geeky wheelbuilder point of view they build up to almost perfectly even tension - with tighter tolerances than any other wheelset we have ever built. From a rider perspective a rounder, truer, faster wheel is the simple result. Sounds basic but this is what wheelbuilders strive for. The rims are all pinned, welded with milled sidewalls. So super strong with beautiful attention to detail. It takes many hours to build a wheelset so using top notch components makes that labour a real pleasure!
The 24mm wide TRIPLE WALLED rim has fabulous cross-sectional strength whilst maintaining a tiny weight. It represents the very apex of the latest developments in the understanding of how to balance forces and tensions in a wheel.
It's a joy to be able to partner these rims with SAPIM RACE spokes (or Sapim FORCE if you are towards the higher end of the weight limit or need an even tougher wheelset!) and the beautifully made Bitex 103 touring hubs, with Japanese ezo bearings. The rear hub has an incredible 6 bearings and the front hub has 4. The unusually high number of bearings ensures lasting smooth rolling for heavier riders - distributing the weight across more bearings than conventional hubs.
