About this bike
This bike is best suited for:

Enjoying longer distance rides & granfondos


The Definition is designed to go a long way in comfort. The geometry is designed for stability at speed and when loaded. The slacker, but not too slack, angles work perfectly with disc brakes and perform dependably on a variety of surfaces, on and off road.

Totally happy with my purchase!

Very satisfied with my bicycle. Delivered quickly. Very clean, nothing missing. Very securely packaged; easy to assemble. I had a few questions, and I tried the chat. I was surprised to find a real and very helpful human being at the other end instead of the lame robots that are so common nowadays. Can't think of anything that should be improved!

Beautiful Bike

The bike was beautiful, albeit with a few things for the end user to check before a ride to ensure safety (e.g. brakes). Packaging was excellent. As a side note, the tool that was included in the purchase ended up being better than the one I bought from Park Tool. It’s currently in my main repair kit.
