Pace RC627 geometry and specification

Pace RC627 frameset in Midnight Smurf blue
Time to record my 2022 Pace RC627 geometry details and build specification for future reference.

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…

Matt is one of the founding Molefathers of the Muddymoles, and is the designer and main administrator of the website.

Having ridden a 2007 Orange Five for many years then a 2016 YT Industries Jeffsy 29er, he now rocks a Bird Aether 9 and a Pace RC-627.

An early On-One Inbred still lurks in the back of the stable as a reminder of how things have moved on. You can even find him on road bikes - currently a 2019 Cannondale Topstone 105 SE, a much-used 2011 Specialized Secteur and very niche belt drive Trek District 1.

If you've ever wondered how we got into mountain biking and how the MuddyMoles started, well wonder no more.
