Pace RC627 geometry and specification
Time to record my 2022 Pace RC627 geometry details and build specification for future reference.
See also: My full review of the Pace RC627 hardtail.
My Pace RC627 arrived via a convoluted route and was finally built up and out on the trails from early May 2022. It is Midnight Smurf blue officially, but I haven’t seen many Smurfs at midnight so I think of it as a kind of murkier version of a mid century powder blue. I would have preferred a slightly more vibrant colour but it looks good anyhow and the paint quality is excellent.
Incidentally, have you ever wondered how Pace models are named? The RC stands for Racing Carter (Adrian Carter being the impetus behind Pace) and the numbers make sense when you realise the 6 refers to the fork travel and the 27 to the wheel size. You can work out from that what a Pace RC529 offers…

Built up a Pace RC627 with a Lyrik Ultimate at 160mm, DT Swiss EX 511/471 wheels on Pro 4 Hope hubs and a mixed Shimano Deore/SLX/XT drivetrain. Running Maxxis 3C DHF 2.3 up front and an Aggressor 2.3 out back at 20 and 23 psi. Chromag bars, DMR stem, pedals and grips with a WTB Silverado on top. This thing is insanely nimble and just rips. More than capable on descents and chunk and it loves being airborne. Manuals come easy and it feels alive on every trail.

Sounds like a really nice set up Paul. I’ve tuned into my Pace now but it would benefit from a better fork and a few lighter components. If only my pockets were deeper.
