I'm running the TT 28T. ~500 mi so far.
I really like the way the bike feels with the 28T. Huge improvement over the 30T
Today just put the Avon 200 on.
Will know more after the weekend.
Still running 03 belt (04 was on backorder, it'll be here wed.)
I'm at the end of the adusters and it's a tad on the loose side.
