Q on brake reach & 27" v. 700C wheels(13 posts)

Q on brake reach & 27" v. 700C wheelsgregario
Nov 21, 2002 7:10 AM
I'm looking at a converted fixed gear on Ebay that has 27" wheels. If I were to put 700C wheels on it would a front brake work on the frame or would I have to keep the 27" wheels or get some super long reach brakes? Thanks and sorry for the possible stupid question, it's been a LONG time since I had a bike with 27" wheels.

If the brakes are older center pulls with long slots they might reach a 700c. You could find some that will work if not. If you're looking at an "around town" beater type fixie, consider keeping the 27's. There are good tires available, they ride plush, and are very durable.

some reach/some dont. Mine reach fine, i interchange 27 and 700 wheels regularly.

Ask the owner how much further the pads can drop.

My guess, being as 'shortreach' is a relatively new concept for the weightweenie world, your 27 incher was build with standardreach, and you'll be fine.

BTW - Whats this 'fg conversion' going for on ebay? Whatever the price, i'm sure you can do a lot better yourself with a garagesale score (not to mention you'll be guarenteed to have proper brake reach)

I wanted to say that as well. If it's one of those crappers sold by "cino59", just do it yourself. If you find a decent donor bike, you can build something comparable for less than the shipping of a bike these days.
So what's wrong with cino59's bikes?gregario

Yes, I have been looking at bikes he's been offering. Frankly, there have been a couple beauties. Why are you calling them "crappers?" By the way, the one I am pondering right now is a Univega, and I think it's offered by someone calling themself "applecart"-something.

I sent an e-mail and the seller said he could not answer the question about reach without unpacking the bike. And this is someone who often has fixed gear conversions for sale so that surprised me a little.

As far as what they are going for I really haven't paying that close attention. I'm figuring around $120-140 for a bike ready to go.

I'm not one to go to garage sales. Not exactly my cup of tea. Plus, I need a fairly large frame, a 62 c-c or so.

I was able to cheat by filing the slot a little to get it to barely work on one bike. On another I ended up needing long reach brakes. I would have had to buy 27" wheels and tires, so the brakes were the cheaper way to go for me with what I had laying around the garage. The good thing about both bikes is that there is plenty of room for fenders.

You can scrounge them off of any number of beater bikes that are commonly found in the garbage. Shimano used to make a dandy single-pivot brake that would work fine. If you are into retro, old Weinemann center pulls come in a long reach size. Shimano is once again making a dual-pivot long-reach brake, if you want to spend the money. A cheaper alternative are a set of new Dia-Comp long reach brakes from www.thethirdhand.com.

The two "frankenbike" 27" to 700c conversions that I've done all required some fiddling with brake calipers. On the current fixie, the frame has a brake arch that is set fairly high for fender clearance (it is a touring frame), so I'm running a caliper that has (I think) a 65mm - 75mm reach.

Like others said, you'll probably be ok with the existing brake. You can also get a "drop-down" brake mounting bolt from your LBS, and use that to mount your brake. They don't cost too much.

Just curious, but is there a reason you don't want 27" wheels?

I got a pair of older super strong box section 27" touring wheels with Record hubs for just a few bucks when I bought my touring frame at a garage sale. I decided to just buy a flip-flop from Harris Cyclery instead of trying to convert the existing rear wheel. I bought some short reach single pivot brake calipers on eBay for almost nothing, and the front one works fine on the 27" wheel. The rear short reach won't work on the rear 700c wheel though. I decided to not even use a rear brake since I'll be running fixed and not S/S almost all of the time.

I've never ridden 36 spoke wheels before and enjoy the bullet proof strength they provide. When you can't bunny hop over potholes on a fixte, its nice to have solid wheels! I'm also enjoying the plush ride the front 27" wheel and tire gives. The tire choices are limited to mosty heavy touring types though. I wouldn't mind putting on a 700c MA3 rimmed wheel on front just to have a better choice of tires. Still, I have no complaints with my current setup.

I did exactly this. I bought an 80's Nishiki on Ebay for $100. Sold the 27" wheels for $58 and replaced them with 700C wheels. The bike had Dia-comp brakes with enough tolerance to accept the 700C wheels. Installing a different front brake wouldn't have been a showstopper, however.
