I have 2 questions on some wheels I was considering. I was in my LBS the other day and a young guy behind the counter was talking to me about upgrading my Allez groupset from the stock Sora to the 105 group. He told me the rear hub wouldn't be wide enough for the 10 speed cassette and I would need to upgrade wheels with a new hub. Not sure that sounds right though.
Second, I'm concerned about these wheels handling my weight. I'm just south of 300 lbs right now and they are only 20 spoke. The LBS owner says he has had a set for years and at 250 lbs he's never had any issues, I just don't wanna dump the $$ into them if the spokes are gonna aspolde.
Thoughts or suggestions?
