Remember to do you rear wheel up properly I put some new wheels on on the weekend and they were fine for the last couple of days, until last night when I dropped into a low gear to go slowly up a short hill (slow moving traffic) and BANG I was laying face down on the road. I'd had no problems up till then but and I think shifting onto the small chainring and dropping a few gears at the back, put more leverage on the wheel and out it popped. No damage done to the bike, except for a few scuffs on the levers. I however, have a nice patch of road rash on my left forearm and I ache just below my ribs. I landed more stomach first than face first, probably for the best, as there is more padding there I'll be double checking my wheels before I leave this evening, please do the same.
