The ‘Primer’ is a bike built for 29 or 27.5+ wheels with geometry designed for aggressive all mountain riding. It is handbuilt in Canada by local fabricator Mike Truelove, in small batches that are painted individually for each customer.
The Primer uses what we would describe as our most progressive 29er geometry to date. The shortest stays possible. Lower than ever BB height. A steep seattube with a slack head angle, low stack headtube and long front center. This combination is the best descending 29er we’ve ridden yet but it still climbs as well as anything we’ve built before.
Building a frame with 27.5+ compatibility means that we had to redesign our ‘yokel’ junction to maximize the chainstay layout clearance. Incorporating a BB92 bb shell and boost dropout spacing also accommodates the most room possible for tire widths as wide as 3.0.

Head tube badges
Bikes are special. The headtube badge is the finishing touch so we’ve always made a point of taking the time to do something interesting with it. Our headtube badges have changed over the years and are an indication of the time each bike was made. Whether it’s a cast bronze, or polished stainless steel, water cut aluminum or a 3D CNC carving, each one represents our commitment to detail.
Our ‘Yokel’ design is a small machined junction on the chainstay that helps accommodate both tire clearance and chainring clearance. Our first versions were huge CNC yokes that bridged the entire front end of the chainstays. Over time we refined this to minimize weight by arranging our chainstay layout asymmetrically and reducing the yoke to a minimal size. It’s one of our most unique frame features and has been copied by other frame makers.
Making modern chromoly frames is challenging when most of the tubes available on the market are from an era of mountain biking long past. After several years of frame production we reached the point where we could design and produce our own custom tubing for the majority of our frame tubes. This contributes to the unique look of many of our frames but more importantly allows us to configure our bikes exactly as we want for each design.
