How's that new KOS ride?
It's very smooth - particularly with the Hookworms fitted. The steering is very quick and precise. The new chainwheel is a 44t which makes it harder to start, but easier to maintain a good pace. I like the strength of the chromoly 'everything' and have no hesitation dishing out some hard hits. I spend a lot of time standing up on it. It's a really good fun bike for doing stuff I'm old enough to know better on.
