INTENDED USE: Road, Sportives, TT's and Tri's.  This is our 42mm deep TARMAC / GRAVEL / CYCLOCROSS FOCUSSED deep section alloy road disc wheelset for clincher/tubeless tyres - Super-aero and super tough. 

Now in its 5th year of evolution - this years version is slightly lighter and more Aero than last years - and  we are sure this is still the worlds only fully clincher/tubeless compatible deep-section 700c alloy disc wheelset.  With a superlative 42mm deep rim, designed by Andy Morgan here in the UK and hand-made for us by craftsmen in Italy  -  it now has a stunning matt black hard-carbon anodised finish. Meaning it looks carbon but has the strength and pricepoint you would associate with alloys. So you really can have it all!

It may also be the world's fastest Alloy disc wheelset.... after all it occupies a unique place: a deep section alloy disc wheelset which has been fully aero optimised around 23-35mm tyres.

In short: It looks like carbon, has the same aero-profile as deep-section carbon, weighs very similar to carbon - and rides more like carbon than any alloy wheel weve ever made. It is also tough as they come. It is also the only seriously deep alloy to be tubeless and clincher compatible..... AND .. Its half the price of carbon!

Light and tough enough for the hilliest and roughest of Sportives, And fast-accelerating enough for racing, and of course, aero enough to ensure that you gain every possible watt of drag reduction.

The k1-42TL AeroDisc is built around our class leading  deep aero alloy rim, with it's pure speed profiling and its stunning "Hard-Carbon Anodised" finish.

The rim has an external width of 24mm and an internal width of 18.6mm - making it perfectly optimised  for 25c/28c/32c tyres (and right up to 50c in fact) in terms of both performance and seamless aerodynamics.

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

BUILD VERSIONS (Hub and Spoke Options)

Miche Italian hubs as standard in our all season AEROFLOW build

From only 1765 grams, in the upgraded Bitex SUPERAEROLIGHT build version with Sapim’s  light aero CX-Delta spokes -It is extremely light for a 24mm wide, fully 'deep-section' alloy wheelset. 

Or upgrade to the lightest Bitex hubs and CXRAY spokes (our SUPERAEROLIGHT** build) to save another 25 grams and further enhance the aerodynamics.

In addition to our choice of fantastically light and reliable Taiwanese Bitex hubs .... if you've got to have the best then why not upgrade to DTSwiss 350 - the best engineered hubs in the world!

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.


The K1-42TL AERO DISC's 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!)
Technical details below.

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 quality DTSWISS and Bitex 6-Drive hubs (for both Centerlock and 6-bolt rotor builds). Weights below for c/lock. Add approx 100 grams for 6-bolt.


Hand built in the UK, and utilising top quality build components. We carry spare hubs, bearings, and should you ever need one - spare spokes!
