Borg31 Disc rim (kinlin XR31 RTS OCR)


A kinlin made rim. It has no decals and a really catchy name so i call it the BORG31. 

This is an offset drilled disc brake rim. Available in 24H, 28H or 32H drilling. There is no braking surface for rim brake calipers.

The BORG31 is a 490g rim that is 24mm wide (19mm internal width), 31mm deep and is an alloy clincher rim that is also tubeless tyre compatible. It's width make it quite stiff allowing lower spoke counts. Better still it is aysmmetric so wheels get a better tension balance. 

Kinlin use a KLM41 aluminium alloy (niobium is one of the alloying elements) to create a very round and flat rim. It has a thick spoke nipple bed so is fine for any rider. 

The rims is more than suitable for road riding or racing or CX use and those that just want to ride can all use this rim. I am actually struggling to find anything I don't like about. 

I keep a fair few in stock for wheel building. Delivery from the distributor is only one working day so if I am out or my stock allocated then I will simply order more.
