Thaddeus Kosciuszko Posted January 11, 2018 Share #1 Posted January 11, 2018 I took my road bike in to the shop for an overhaul. Long overdue. While taking it to the car I noticed the rear wheel was out of true. Well, truing the wheels was part of the overhaul deal. The mechanic at the shop looked a the wheel and peeled back the decal, thus discovering the real reason for the wobble. No fixing that. I was downcast, as the rims I have on this bike roll like lightning - I don't know why, but they do. (Theoretical physics says the weight of the rider is not a factor, supposedly.) Anyway, the guys I ride with have bikes of much higher caliber than this one, and on the downhills my bike would just roll right past theirs. It's probably time, as the rims are original and I bought the bike in 1994. 1 Link to comment Share on other sites More sharing options...

maddmaxx ★ Posted January 11, 2018 Share #3 Posted January 11, 2018 Doesn't larger mass make the force of air resistance create less negative acceleration.......assuming that more mass does not create enough more area to increase the force of air resistance.

ChrisL Posted January 11, 2018 Share #5 Posted January 11, 2018 I always tell my wife my bike rolls better downhill because I weigh more but I really can't explain it. I know data suggests this isn't so but I just don't know why I coast so much faster than her. She has high end wheels and similar tire/tube set up as I do but I just go faster coasting. I sometimes ride with these guys and we always have a coast down hill challenge on this long straight hill. Well regroup at the top and then all take off together at the same pace and coast. I've never lost that "race". Can't explain it... Link to comment Share on other sites More sharing options...

I replaced the wheels when I saw numerous hairline cracks develop around the eye as I figured what happened here was the next step. Link to comment Share on other sites More sharing options...

Kzoo Posted January 11, 2018 Share #8 Posted January 11, 2018 My gosh what's the issue here? Put the decal back on. It's only the real wheel. Now if it was the front wheel I'd be concerned. 1 Link to comment Share on other sites More sharing options...
Razors Edge ★ Posted January 11, 2018 Share #9 Posted January 11, 2018 Save the hub. That's the part that you actually seem to like. Rim schmim! All about the hub. Tom 1 1 Link to comment Share on other sites More sharing options...
donkpow Posted January 11, 2018 Share #10 Posted January 11, 2018 The problem is the spokes are too strong for the wheel. You need weaker spokes. Problem solved. 3 Link to comment Share on other sites More sharing options...

smudge ★ Posted January 11, 2018 Share #15 Posted January 11, 2018 FULCRUM!! You need Fulcrum wheels! That's what I have on my Roubaix, and I always out coast everyone downhill! Then again I usually have more mass than they do... hmmm. Link to comment Share on other sites More sharing options...

I hadn't thought about that, and checked the repair ticket. Says "Save old parts: No". So I emailed the shop and asked them if they would save the rear wheel for me. 1 hour ago, jsharr said: Thatrimis Kraptasticlyscrewed Link to comment Share on other sites More sharing options...

Parr8hed Posted January 12, 2018 Share #19 Posted January 12, 2018 You are correct. No Fixie. Going to fixie would not help. Probably MORE stress on that wheel. Gears are the way to go. Link to comment Share on other sites More sharing options...
