I'm building a fixed gear that's going to be a polo specific bike. I'm halfway through and have run into a problem. I'm using a mountain bike frame but changing the fork, stem, bars, and obviously wheels. Since I changed out the fork, it was easy to throw on a road front wheel, but the frame is to wide to put a flip flop on there that I want. I've tried to research this but haven't come up with anything but people who have to narrow frames (the oppisite problem). If anyone knows about any kind of spacers or anything, then that would be great. I'd rather not have to deal with trying to fit a new hub into a flip flop wheel. Thanks for the help.

Keep it cool, y'all, and avoid escalating arguments beyond the topic at hand.

Word, thank you, Hairnet.

OP, Google 135mm flip flop hub.

Scrodzilla

Go back and read the last sentence of the original post.

As long as your axle is long enough, all you have to do is add some spacers to match the width of the frame. You could even use some cheap washers...just stack them on the axle on the outside of the locknut. If your axle is too short, things could get more complicated. What sort of hub are you using?

Steev

I'm not quite sure what the OP is asking for, but if it's a flip-flop hub with 135mm OLD spacing, then what about using an MTB disk hub, spacer kit and cog on the cassette side for freewheel and a bolt on cog on the disk mounts for fixed.

Scrodzilla

Really???

Just crank down on the bolts and bend the frame into the hub. Booyah.

^If it's a steel frame, just crank those nuts down and be done with it.

135 frame squished down to 160mm could get a little ugly even in steel.

Seriously, this whole thread is ****ed.

LesterOfPuppets

Hahaha. Phone corrected my number. 120mm is a pretty big squeeze. Dropouts not even close to parallel.

Spacers/washers outside locknuts idea above will suck if horizontal dropouts cuz axle slippage.

Oh man I was literally laughing so hard reading this thread. Seems all the basics are covered and doesn't look like the OP is coming back.

LesterOfPuppets

He might be back. Hopefully with pics or at least make/model/year specs.

RaleighSport

True, and it might be a very dope polo bike.

bones_mcbones

I'm pretty sure my axle spacing is at least 15mm less than the frame spacing.

hairnet

Just because you can doesn't mean you should.

Take the wheel out of the frame, lay the frame down on the side, stomp on the upper dropout. Did it move? Check against your wheel. If not, stomp harder, longer. Keep adjusting until the wheel fits. You are trying to fit a 120 width into a 135 width dropout, which is a significant width to squish to where you need it to be. Steel is also springy, so you can't use the wheel or hub to arrest the squeeze. And if you apply too much force, you can bend the frame in ways you will be unhappy with. Stomp, check, stomp, check, stomp, check. And hopefully not stomp, check, "Oh, fu..."

I've used washers on the outside of the locknut on many occasions for a quick fix....slippage wasn't a problem.

LesterOfPuppets

I have also. Success rate about 75% on horiz. dropout MTB frames. I've been more successful with serrated washers than smooth. Low success rate (to my way of thinking) and PITA wheel reinsertion keeps me from suggesting anyone do so on a bike they're gonna use much.

mihlbach

I thought it would be a quick and easy solution for the op.

bones_mcbones

you crank down those nuts yet?

Scrodzilla

It would have been much quicker than making sense of this thread.
