Since the release of Sergio Layos’ signature Sierra frame, we have always wanted to do a more trailsspecific frame. The new Motosierra frame is a Sierra Frame version for the die hard trails riders witha trails specific geometry.It features welded chainstay brake mounts and our new 5mm invest casting dropouts for 10mm axlecassette, that all these pegless riders will love. Something important about this frame, is that weare teaming up with Sergio to donate a % of the sales to a set of trails (To Be Announced) to supportthe hard work and fun being had in this woods! Available in Gloss Dark Red and Gloss Black colors.Other important features are the welded chainstay brake mounts with the cable through the seattube system. This classic system is very popular among trail riders but the available hangers werenot quite designed for it. Until now... We are including our new Manual Nano hanger designed for thisbrake set up without any flex and easy to install.
