£300 OFF : 2020 Kinetic-One “K1-42ST AERO" Deep Alloy wheelset



Rated to 150kg -Quite simply... The world’s first and only deep-section Tubeless/clincher alloy wheelset aimed at bigger guys.


INTENDED USE: Sportives, bunch races, time trial and Triathlon (from Sprint to IRONMAN distance.) This is our multi-functional custom built ALLOY aero wheelset. This is a super tough - super aero racing and training wheelset that is equally at home on Summer sportives and TT's, but also tough enough for fast winter commutes!

It’s for riders who want all the aero benefits of carbon - but want to stick with a more robust material and also save a significant sum of money at the same time. Not the lightest wheels we do of course but an enduring best seller ... now with the added benefit of being tubeless ready.

Super aero rims complimented by superb black spokes and hubs. We offer a range of build options - to suit your budget, your weight and depending whether your focus is on ‘all out aero’, or on reducing weight... or on the sheer look of these wheels!

Our standard tough build is the the fabulous AEROFLOW  option - with PSR AERO spokes and MICHE PRIMATO hubs, the lowest drag hubs available anywhere! (More>>) This build is available is 2 spoke options (24/32 or 32/32) and is rated up to a maximum 135kg.

Or for really big guys we have the AEROTOUGH build. Using Sapim Force spokes and the amazing Bitex BX103 hubs - this is a true high performance and reliable wheelset.

It seems inconceivable to us: There was not a single deep-alloy TUBELESS & CLINCHER READY wheelset available anywhere on the planet... yet the benefits and need for them is so self-evident. So, in keeping with our long experience of innovation in wheel design... we came up with our own wheels. 

Fully clincher and tubeless ready they are 23mm wide externally and 17.5 internally. Fully performance optimised for 25c and 28c tyres (will also take a 23mm if you have frame clearance issues ... or if you are old skool!)

The rims are handmade for us in Northern Italy by craftsmen who we’ve worked with for almost 20 years.


Your wheels will be hand built to order here in the UK by Andy Morgan, owner and founder of k1 wheels. Turnaround time is most often 7-11 days. (current build times are shown at checkout).

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