Pace RC127 frame – just in

650b steel hardtail prototype

It’s not yet reached production, but BikeRadar have taken delivery of the RC127, a new mountain bike frame from British firm Pace. The 650b steel hardtail will retail for £499.


The RC127 is made from Reynolds 853 steel, which immediately sets it apart from a lot of its alloy-framed competition, even more so when you notice the steel head tube gussets and slim, loop-bridged rear stays. However, there’s nothing retro about those 650b (27.5in) wheels or the potential capability of the frame.

The head tube is compatible with tapered forks and has been designed around a 140mm travel model. There will be dropper post cable guides and ISCG mounts on the production frame. At the rear, there are adjustable dropouts, and a 142x12mm version is in the pipeline.

Spec-wise, this pre-production model is kitted out with a short stem and wide riser bar, both by Truvativ. The 650b wheels are Stan’s ZTR Arch EX rims with Hope Pro 2 hubs and Schwalbe Nobby Nic tyres.

The rc127 frame is designed around a 140mm fork and 650b (27.5in) wheels, and pace has built this prototype up with a rockshox revelation rct3 fork:

The 140mm fork is a RockShox Revelation RCT3 and the tapered steerer runs into a Hope headset. Power transfer is taken care of by SRAM X7 parts, with speed-scrubbing being handled by a set of Avid Elixir 9 hydraulic stoppers.


There will be a complete review of the Pace RC127 in issue 153 of What Mountain Bike, on sale 24 September, and we expect more information to be available from the Pace website soon.
