Hi there

Nashbar has On One single speed wheels, 29inch wheel set for 109.95 marked down from 249.95, which would be great for a cheap single speed. Anyone ever used these? Anyone know if they're good, bad, or ugly?

sorry, here's the addy:

if you could find a cheap 29" frame to go with them. and if you wanted to

Mudhiker

ooh, I'm interested in these since my bike has 135mm spacing...and the threaded part of the hub is already in the right spot for single... but it's not a track hub so I can't just slap a track cog on it? Argh. I don't think I'd trust the locktite trick.

Are they really marked down? Or is it another Nashbar "mark down"?

If you google on mavic a117 it looks like the rims are about $25-27 each, so $109 sounds pretty reasonable for a built up 700c wheelset. Those wheel retaining "nuts" look kind of funky though, they could probably be replaced at an LBS. I'd probably get em if I was looking for a SS wheelset.

dkb

whoops, should have been google on mavic A119...

eddiebrannan

hello? they are TWENTYNINE INCH WHEELS. they need a 29"-specific frameset. you can't just throw these on your current bike

psstt. Eddie, 29er is a 700c. I would be more concerned with the 135 spacing issue.

eddiebrannan

duh. yea they are. oops!

wheel sizing is so screwed anyway. 700cs are smaller than old school 27" rims, which makes 29s smaller than 27s. i had no idea that modern inch size didn't correspond with actual rim diameter measured in inches until i was shipping a 24" wheelset i sold on ebay. was measuring the box dimensions and kept thinking i'd screwed the measuring up because the box was less than 24" square.

The measurements include the tires. It's 29" with the tire on. 700c is 700mm with the tire on. Both are 622mm outside diameter rims. Of course depending on what you put on for tire, that will affect the final wheel size.

That's what the 'C' is all about. A - D specified a standard French tire size which together with the appropriate rim would add up to the number. So a 650C wheel would have a 650C rim designed to take a 650C tire. A 650A wheel would have matched 650A rim and tires. Both wheels then would come out to 650mm even though the 650A rim is quite a bit larger than the 650C.

700C is supposed to take very large balloon tires. (700mm - 622mm = 78mm!)

eddiebrannan

so a 700a rim would be larger than a 700c?

bostontrevor

If you could find one, yeah.

eddiebrannan

so why did 700c become the standard across the range of tire widths?

bostontrevor

Good question. I know it's a popular size with a lot of Northern European utility bikes (the old 28" wheels) which would make for a lot of availability. I'll go a step further and suggest that vintage French bikes probably also took big fat tires and 622mm rims. Maybe road bikes also came with similar wheels, though probably not. At any rate, it probably became easier and useful to start experimenting with smaller tires on the most commonly available wheels. Why are mountain bikes 26"? Because that's what Schwinn put on their cruisers. Sometimes it's just an accident of history.

Just a guess.

bostontrevor

Oh, and I wouldn't mess with those wheels unless you've also got or are willing to get a new bottom bracket to go with the 52mm chainline.

emayex

can i fit the 29 inch wheels on my steamroller?

dkb

when they say 135mm spacing, i guess they mean it. those bearing cups look like they were designed for 135mm spacing, no spacers to fudge with.

On One Inbred hubs

r-dub

find a copy of the last rivendell reader...big article detailing the history of 650a/b/c and 700a/b/c

bostontrevor

Care to summarize?

max-a-mill

i just got that rear hub laced to a delgado rim for my crosscheck commuter (yes those are roadbike diameter).

pretty cool hub very similar to a surly. (same bearings i think)

warnings:
1. if it is like mine the rear is singlesided threaded for freewheel only (no fixed side)
2. the picture of the inbred on the hub body is very frightening (not that you look at the hub too much).

that looks like a good deal though, if you know how to true a wheel and they aren't built too poorly. i payed over 50 just for the rear hub.

All of the wheels were built to have the same overall wheel size (inflated tire diameter). Skinny tires used larger rims and fatter tires used small rims to achieve this. Different rims sizes for different width tires (A, B, C) that all yielded the same size inflated tire.

bostontrevor

Umm.. right. That's sort of exactly what I said right here: https://www.bikeforums.net/showpost.p...0&postcount=11

I was referring to r-dub's post right before mine that mentioned some history of the different sizes.

riderx

HaHaHaHa! Sorry, I missed your earlier post.

Anyway, as far as history goes, it was "back in the day" that they used to do things that way. I don't think they mentioned any other history in the article except for how there were different rim sizes and what the a, b, c designation stood for.

oldskoolboarder

Seems to be only single sided. Is that right?
