The Velocity A23 rims are a 23mm wide clincher rim designed to open up the tyre and improve handling and comfort by increasing air volume in the tire, as well as improve aerodynamics. Most clincher rims are 19 – 20mm which is narrower than a standard 23mm tyre.
Velocity arn’t the only people trying this wide rim concept: HED have the Ardennes, C-4 have the VT-22 and the new Zipp 303 clincher and tubular are 23mm wide. Stan’s also have a wide, tubeless-ready road and cyclocross rim in the works.
There has been quite a bit of online debate about whether a wide rim will do what is claimed so I wanted to build a pair for myself and for customers to try.
The Velocity rims are both below 430g which is light for such a wide rim.
I used red DT Swiss 240s hubs and laced the front wheel 24×2 using DT Swiss Revolution spokes and alloy nipples. The rear wheel uses DT Swiss competition spokes on the driveside and Revolutions on the non-driveside. As I was unsure about how stiff the rims would be considering their light weight so I opted for the stiffer Competition spokes on the driveside but I was impressed with the stiffness of the rims so in future I know what type of spoke will suit different riders.
The wheels built up really well and at 1467 grams are very light. I’ve managed a few hundred km on them and they feel very nice on the road. Road ‘feel’ is very good but the thing that impressed me the most was how well the wheels turn-in to a corner. Gary had a quick ride and was impressed and the wheels are off to Hamish for a few weeks while I’m away.
