We'll be riding the 26km. Nope. It is a fixie, set in 1:1 gearing ratio ie: no gearing. What that means for us, is that to brake or slow down, we need to apply backpressure whilst we pedal. I am running a brake on my 29er, but it is used as a drag brake to take some pressure off the knees on the long downhills. I don't use it to stop suddenly, as I would faceplant painfully JReggae doesn't run a brake at all.
