New design of wider 50mm deep, tubeless compatible, carbon wheels for racing, TT or just recreational speed! Fast and aero. Fast enough to win the 2022 UK round of the UCI World Gran Fondo series Handbuilt in the UK by a professional wheelbuilder rather than by a machine. Rims are produced by Carbonal to our spec. 100% Toray carbon fibre incorporating a titanium reinforcing band. Mix of Toray T800 and T700 carbon weaves for improved stiffness and resiliance, Brand new high heat resistant resin/cloth used in brake track area rather than the more common 'basalt' layer. These rims have a brake track resistant to temperatures of 255oC (our standard rims with basalt brake track are 210oC resistant and cheap carbon rims can be as low as 150oC resistance). This is the same technology as used by the top brands costing £2000+. The brake track looks pretty smart as well! 50mm deep 'U' shaped aero section 28mm wide at the brake track and 30mm wide at the mid-point in the section and a 21mm internal width. The increased width gives a bigger contact area for the tyre on the road, improves the aero performance by being the same width as the now commonly used 28mm tyre size and improves ride quality. The rims can be used with tubed tyres or tubeless with the appropriate rim tape and valves. Suitable for road tyres from 25mm - 35mm width and CX clinchers. 20/24 spokes. Max recommended rider weight 85kg with Novatec hubs and 105kg with the stronger optional hubs listed below. These wheels are wider than normal. The buyer must be sure that their bike frame has sufficient clearance. Our demo bike is a 2012 Canyon Aeroad. Loads of clearance for the wheels but the Shimano Durace direct mount brake calipers required a slimmer brake pad (Swisstop Black Prince Evo) to be used. Centre mount calipers open further and should be OK with standard width brake pads. Rim brakes only and a carbon specific brake pad must be used. We recommend the SwissStop yellow or Black Prince brake pads for the best performance. (Mavic yellow brake pads are made by SwissStop and seem to be identical). We use Black Prince.
Carbon clincher rims (of all types from £250-£2500) can suffer from brake track problems if heat is allowed to build up by long periods of gentle 'comfort' braking. Avoid this by braking harder for a shorter period of time. These rims minimise the risk but if you are uncomfortable using this technique we suggest looking at alloy wheel alternatives. Novatec A291SB-SL front hub. Standard road bike dimensions of 100mm wide with QR fitting. 20 spoke holes. These are really light and weigh only 60g. 2 x high quality sealed bearings. Gloss black.
Novatec F482SB-SL rear hub. Standard road bike dimensions of 130mm wide with QR fitting. 24 spoke holes. The lightweight F482SB-SL weighs 228g. 4 x high quality sealed bearings. Gloss black.
The standard freehub is Shimano 11 speed compatible and comes with an alloy spacer to allow use of 8/9/10 speed Shimano or SRAM cassettes. SRAM XDR and Campagnolo 10/11 speed freehub available at no extra cost.
Miche Primato (Shimano or Campag) hubs available for heavier riders at no extra cost
Supplied with lightweight Novatec/Miche QRs
The spokes are super high quality Belgian made silver Sapim CX Ray bladed spokes in silver fastened by silver Sapim 14mm alloy nipples. CX Ray spokes are among the lightest spokes available but have great strength and aero properties. Unfortunately they are also rather expensive! Cheaper wheelsets built in the Far East generally use much cheaper and less efficient spokes. The wheels are built using a radial pattern at the front for lowest weight and better aero performance and 2x/2x at the rear for strength and reliable power transmission. Total wheelset weight is around 1495g. Options: Miche Primato hubs - recommended for heavier riders and winter use - same cost. 145g heavier. Bitex RAF10/RAR9 hubs (15g lighter, higher spec bearings and freehub) +£45 Hope RS4 hubs - recommended for heavier riders and wet use, 100g heavier +£135 DT Swiss 350 hubs - recommended for heavier riders and wet use, 130g heavier +£95 Black CX Ray spokes - as pictured - +£20 Coloured alloy spoke nipples - as pictured - choice of gold, orange, green, red, blue, purple or black +£16 Tubeless set-up with Orange Seal rim tape and tubeless valves +£22 Swisstop Black Prince carbon brake pads +£30 Shimano/SRAM or £34 Campag All our wheels are handbuilt to the same high standards. The wheels are trued to within +or- 0.2mm and spokes uniformly tensioned to within 5% a side. Please look at the other wheelsets and products available in our shop.
