Description
Description
The Ridgeline SS is our newest single speed XC focused race frame. Updated to perfection as a modern hardtail, designed for today's most demanding cross-country and endurance events with sliding dropouts for the ability to run single speed.
What sets this model apart from the rest is the precise combination of a diamond shaped 3/2.5 top tube, over-sized HELIX downtube and a lower center of gravity. These key features allow the rider the ability to confidently dive through corners and maintain total control at high speeds, even on the most technical descents. With a longer top tube and slackened head tube, the Ridgeline SS is designed around shorter stem lengths and 120mm-130mm travel suspension forks creating the perfect hardtail that is stiff, strong and race-ready.
All frames are made in Chattanooga, TN USA by Lynskey Performance. All frames come with a LIFETIME WARRANTY.

Shipping
Our unassembled shipping selection will arrive to you with the bottom bracket installed in the frame and the crown race installed on the fork. All other parts will be off of the bike and need to be fully installed and setup.
Our assembled shipping (for US customers) will be built up here at the factory and tested before shipping out to you. This will arrive to you with the front wheel removed from the fork, the handlebars out of the stem and and tucked next to the frame, and the seat/seat post removed from the frame.
Sizing/Geometry
Sizing/Geometry
Please refer to our geometry chart below for detailed sizing specifications.
You can select your preferred size when placing your order, and if you have any questions about fit, don’t hesitate to reach out. We’re happy to walk you through the details and can adjust your order if needed.
If you’re between sizes and seeking a more comfortable, long-distance fit, we typically recommend sizing up. This will give you a taller stack height and a slightly more upright riding position for added comfort.
If you prefer a racier, more performance-oriented fit, opt for the smaller size for a more compact and agile feel.
