Wheel Upgrade, Need spacers?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Wheel Upgrade, Need spacers?

Hello everyone. I ended up running over my wheels from my starter road bike, and I would like to replace both wheels with this set:

https://bikeisland.com/cgi-bin/BKTK_S...ls&ProdID=1450.

My bike is a 7 speed. On this description it mentions that 7sp will need a spacer. Can I do this myself? Or do I need to take it to my LBS? Thanx for any info.

By the way, this starter bike is the "Wal-Mart" Schwinn Varsity that was out a few years ago. I really don't wanna junk it just yet.

Thanx

It depends on what spacer you need; if you have the tools you can get different spacers and find the one that works for the cassette you are using.

5/6/7sp road bikes used a 126mm spacing rear wheel.
when the road bike business switched over to 8sp, the spacing got wider to 130mm. 9/10sp also use 130mm

yes you need a spacer to use a 7sp cassette on an 8/9/10sp wheel. otherwise it just flops around.

Will the 130mm wheel even fit your dropout?

Good question. If the frame were steel, you could just open the dropouts and jam a 130 in there (I've done it several times with older frames), or you can cold-set (serious cyclist talk for "bend") the frame to accept it. Aluminum doesn't like to bend, and I don't know if 2mm on each side would be enough to compromise the frame.

Man, sounds too much of a hassle. I guess I'll just replace the front wheel, even though it will be a different, but who cares, it's just my commute bike. Thanx for all the info!

I'm pretty sure its 130... Not all 5/6/7 speeds are 126. That being said, you will need a cassette if you have a freewheel (I think a co-worker used to commute on one, and if I remember correctly its freewheel).

Ok, lets say I want to change the wheels out on this bike afterall, what would I need in case I want to change the gears to an 8 speed? Would it even work? Or do I have to change shifters as well? Thanx for any info guys.

You said you had 7 speed, so you would need 8 speed shifters, (the new wheel w/...) an 8 speed cassette.

7 and 8 speed is spaced the same. the hub got wider to accommodate the extra cog.
you can use 7sp shifters on an 8sp cassette but you'll only get 7/8 gears working. doing the opposite, 8sp shifters on 7sp cassette leads to a spare unused index.

that's why you see 7/8sp chains.
