INTENDED USE: The SUPERLIGHT version of our Ultimate Road Disc-brake wheelset saves almost 100 grams in weight but with no reduction in strength. Specified for maximal speed and acceleration across a range of disciplines

From sportives to triathlon and Strada Bianchi - they also feature prodigious strength (rated to 115kg). 

Combining all the knowledge and experience we've built up over the past 20 years. The 46SL's combine low weights, as low as 1445 grams, with maximal aero gains, married to the latest rim profiles (to get the most from modern tyre systems).  

At 30mm wide (21mm internal) with superb aero characteristics married to the superlative strength that filament winding offers - they are designed for TARMAC, TRAIL and CYCLOCROSS.

The weave pattern is visually stunning but its primary purpose is practical above all else. It has a unique characteristic in that it concentrates the carbon fibre density at key parts of the rim such as around spoke holes. This increases strength and reduces weight.

We designed them specifically to get the best out of the new generation clincher and tubeless tyres. Optimised for road tyres in the range of 25 to 32mm range - they will also take gravel/adventure tyres right through to 50mm and beyond.

Our objective for this wheelset was simple and clear: To achieve a 'strength-to-weight-to-aero' ratio as high as current technologies will allow.

Our premium full-carbon wheelset utilises patented filament-wound, robotic-built, ultra-high temperature K1-46SL rims. 
 
Sounds fancy: Filament winding technology is an automated method which has revolutionised rim consistency in the manufacture of full carbon wheels. Each rim is made from single carbon filaments precisely wound into shape - with no joints or junctions - this enables a uniformity and strength that builds into the roundest and most balanced wheels possible.
 
This extends into the quality control stages where each and every rim is X-Rayed to ensure uniformity and compliance.

This is the newest of our K1 carbon wheelsets. At 30mm wide, with a full carbon u-shaped rim profile - it is aimed at those riders who prefer an ultra-modern wider rimmed wheelset.

Your wheels will be hand built to order in the UK. (current build times are 14-21 days).

BUILD VERSIONS (Hub and Spoke Options)

When specced in the fabulous SUPERAEROLIGHT ++ Build. This marries Bitex’s lightest performance hubs with the legendary SAPIM CXRAY spokes and takes the weight of this build option down to from “1445 grams.

Offered With Full Warranty and professional mechanic support in-house.

It's an incredibly fast-moving time for road disc systems at the moment with lots of competing standards for Axle types and frame fitting methods and for rotor fastening.

They are handbuilt to order and are available for the whole wide range of modern axle and rotor fitment systems. Whatever your frame needs we can configure these wheels to your bike. And even if you change your bike - the hubs are all simply convertible to all the other axles standards! We think that's massively important as it future-proofs your wheels! (no one wants to be left with the betamax of hub types and obsolete wheels!)

Or just drop us a line If you don't know what system your bike has (you won't be alone -  many people very understandably don't know, they just want to ride their bike after all!)

AXLES : We can configure your wheel axles to meet your frame requirements. So whether you have standard quick release or the more modern "thru-axle" setup, or whether you have 135mm or 142 mm rear spacing, we can supply them ready-to-roll!
 
HUBS : We use the superbly versatile and lightweight Bitex 6-drive hubs, WE NOW ALSO OFFER Carbon-Ti hubs,  in both Centerlock and 6-Bolt flavours. Weights below for C/Lock. Add approx 100 grams for 6 bolt.

The new generation wide rims are perfectly suited to disc-brake riding. They are very strong, yet very light and very forgiving to ride.
