BORG31 Disc brake wheelset

£430.00


The BORG31 Disc is a disc brake only wheelset for what ever and where ever you want to go. Road riding, CX/Gravel use or touring. The rider weight limit is 100kg. Higher spoke counts are possible. This wheelset is built to be robust. 

The wheels can be built for the Cannondale 6mm offset rear used in one of there CX bikes.

24mm wide 31mm deep and tubeless ready . 

The wheelset comes with 8/9/10/11 speed Shimano, 9/10/11 speed Campagnolo or SRAM XD driver, freehub bodies. The wheels have hubs that are convertable between Q/R compatible and 100x12mm or 100x15mm and 142x12mm thru axles. The wheels are tubeless ready too as the come with a tubeless kit. 

The wheels will be supplied 100x12mm and 142x12mm as standard unless you specify Q/R.

The rim used is the Kinlin XR31 RTS OCR (now you know why I rename them). The rim is an offset design and this improves tension balance and therefore extends spoke life. It is 500g in weight and very stiff. The only drilling I use is 24H because that is all any one needs within the weight limit.

Also the offset rim improves spoke tension balance and there spoke life is improved.

The spokes used are Sapim CX Force. These are aero spokes but they are thicker in the blade section than the CX-Ray and they have a 2.2mm diameter at the elbow. Black Sapim self locking alloy nipples are used and Rock n Roll nipple cream acts as a thread locker and corrosion inhibitor. 

The hubs are Miche SWR DX (6 bolt rotor mount), Miche Race DX (centrelock rotor mount), DT Swiss 240 (centrelock rotor mount) or Carbon Ti (6 bolt rotor mount).
