i bought my first fixie (kilo tt pro) about three months ago and have not had any problems with the bike. my only problem was letting someone at a bike shop work on it. long story short the mechanic stripped my hub. i have since bought some tools and plan on doing future modifications myself. i am asking for guidence in choosing the brand of hub to replace the stripped one. since i purchase an entry level bike, i would like to upgrade. i would also like a suggestion as to which is a good wheel at a moderate price as it might be easier to replace the wheel than finding someone to lace the spokes. in advance, thanks for your time.
