Wheel Size Questions

[FSSS]

This may be a silly question to the roadies out there, but...

Does anyone run a 700c wheel in a frame that originally had 27" wheels??

According to Sheldon Brown the difference between the two rim diameters is only 8mm. I figure 8mm is a pretty small distance - but is it enough to have problems with brake pad/rim alignment???

My next project is an early-80's Trek road bike and I'm wondering if I can put 700c wheels on it.

Thanks.

...the larger rim/tire combos clear your stays and fork crown you should be able to find canti's and some v-brakes (Avid Tri Align?) that accomodate a really wide range of movement.

This is especially true for MTBs squeezing 700c wheels into 26" frames/forks.

I didn't have any trouble putting 700C wheels on my 80's Schwinn - there's lots of clearance. The brake pads are almost all the way at the bottom of the arms, but they line up nicely...

Thanks Aaron.

It's good to hear it worked for someone in the same situation.

Although the brakes may not be an issue - I might go with a coaster brake :crazy:

Ya dude! I was just looking at that same wheel yesterday. I picked up an old 3sp cruiser bike from the 40's or 50's over the weekend, and it's got these wacky 28" wheels, and no place to mount any kind of brake on either end of the bike. So, coaster it is!

OR, I'm thinking of doing up a fixed gear with a front drum brake - ANT-bike style:

Hey Pete,

You may get the brakes to reach, there are a couple of different sizes - but you may have the best results with an older center pull as they usually have the longer reach. If you want to get techie, there are center post lowering devices that have the offset.

You can always grab a metric tape measure and make a trip to the pedalfile (www.oneonone.com basement). They have boxes of different brakes to choose from.

I've never been down in the basement, and I'm kinda scared to go down there...

I figure I'll never be able to say "no" to a project once I know what is available down there.

I may have to check it out for this project - looooow budget!

That site is awesome! Sweet bikes... especially that 29er.
