Enjoying my fixie too. Swapped handlebar, saddle, and seatpost right away to get the fit comfortable. Next bought a couple of different sized cogs and the right tools. Running about 70 gear inches feels about right for the rolling hills here.

Thanks for all the advice I've received, I plan on getting a brake installed when I pick my bike up, I won't use the word Fixie!! and deff. going to get clipless pedals. I was thinking speedplay, or maybe the ones one of you guys recommended (SHIMANO M324 Clipless SPD Platform Pedals) not sure and advice on pedals???

Thanks Bonetti
