Need help
 

This is probebly them dumbest question, and i know i face ridicule for it, but my bike currently has 27in rims on it, and im looking for a new wheelset witht he deeper rim. the one i want to buy says 700c wheel set, so will this be compatable with my bike?

what frame are we talking about here?

generally speaking yes, this should work OK, but there are a few things to consider, are you considering running brakes? fixed? SS? more details...

The bike it about a 58cm, and the wheel set would be fixed

well at least you answered one out of three questions.

i wont be using brakes,
i dont know what kind of frame it is

If you won't be using brakes, this shouldn't be an issue. The 700c rims are slightly smaller in diameter (8mm) and therefore might require long-reach calipers, but this is all obviously a non-issue with no brakes. The reason your frame is important is to check your dropout spacing, which will determine what sort of hubs will fit. Do you have any info about the frame at all?

Track or road, decade, any of this would be helpful.

Its a road bike, and they have vertical drop outs, im not sure what the spacing is, but i can find out. The bike was a 10 speed, if that means anything

If by "ten speed" you mean it took a ten speed cassette (i.e. modern road spacing), it is 130mm. If it's a "classic" ten speed (2 x 5), it's probably 120mm. Modern track spacing in the back is 120mm, so most fixed wheelsets you come across will use this spacing and therefore fit the classic ten speed just fine out of the box.

What is this mystery frame? What does it say on it? If you don't yet have it, where is it coming from? It won't take much info to get a positive ID on the spacing.

Im going to so scratch around on the brand plate. Who ever had it first spray painted over it.illl get back to you

did have much luck. The only thing i could pull from it was that the logo was primeraly green, and had crome coloers curves going tword the bottom/center of the badge

Did you mean to say horizontal dropouts? Unless you get lucky on your gearing combination you won't be able to achieve correct chain tension using vertical dropouts. You don't want to run a brakeless fixed gear with sloppy chain tension.

Really, it's probably inadvisable for you to run a brakeless fixed gear on the street at all [even if the dropouts are horizontal] but I have a feeling based on the question you posted this thread to ask that looking cool on your bike is more important to you than safety or proper mechanics and bike setup.

I meant horizontal, and i would probeblly use a brake on the front wheel....But the reason i need a new wheelset it because the ones i have are pretty rusty, and really beat to hell.

The answer is yes. A 700c wheelset will work with your frame provided that the hub and rear dropout spacing match.

A properly spaced hub, or cold-setting the frame (only if the frame is steel; read Sheldon Brown) will ensure that.

Your brakes, if any, will need to be longer than usual.

Front brake = good.

Assuming the frame is steel, you don't really need to worry too much about dropout spacing if you are using a modern 'track' hub. Either the bike is already 120mm spaced and the wheel fits or it is 130mm spaced and you have to squeeze the dropouts together a bit to install the wheel. You don't usually have to manually respace the rear triangle unless you are trying to put a larger hub into a frame with a smaller dropout spacing (eg. When I added a 132.5mm spaced IGH hub to my bikesdirect FG with 120mm spacing)

If the frame is old enough to have used 27" wheels then there will be no problem with the rear spacing. Get a 700c wheelset with 120mm wide rear hub.

Brakes might be a problem. I had to go with long reach brakes on my old Raleigh conversion even though I was using 27" wheels. The Tektro R556 is a nice long reach brake that work just fine.

Alright. Thanks guys for the help.
