well if you don't go mtn biking then yeah get slicks, if your off road is gravel trails ect and not realy mtn biking get somthin thats not totally slick and not as skinny, ie somthin like 1.75 wide and with a high number of small "knobs"
Like I said in that second thread, I can fit 700c wheels with 28 mm tires on my C'dale Rush to make it a fast, responsive city bike. Putting knobbies back on is as simple as changing the wheels. Of course, it's hardly an extra expense, because I already had another bike.
Don't want to highjack the thread, but was interested in reading of folks using different wheelsets on one bike.
How does this work out with wear to the drive train? The cassete on one wheel might have different wear to that on another wheel, yet you will be using both with the same chain and rings. Doesn't that give accelerated wear?
as long as you change your chain when it gets worn out shouldn't be a problem, just get a chain checker or take it to a shop from time to time, wear on the cassette doesn't really happen until after .75% stretch, and usually isn't a problem until you get close to 1%, although if you load the pedals crazy hard you can wear the cassette out earlier.
I run 2 wheelsets on my cyclocross bike, and its been really great, i can throw on the set with slicks when i don't wanna be stupid and commute to work on my race bike, and don't wanna ride that far on my ss, the only issue was that the rims had diff width which meant i had to play with the brake barrels a tad but they where close enough it didn't throw off pad alignment, but if you are buying a second wheelset i'd try to make sure you have similar rim widths if you run rim brakes, if you run discs then you could prolly throw some 700c wheels in there
if you had a worn out cassette on one set you would cause fast chain stretch and then wear out the other cassette, so if you run multiple wheels you just have to keep on top of maitanence but you should do that anyway, and i imagine most people on bf know bout that anyway.
