Fitting Ss/track Flip Flop 120mm To Std Geared Bike?

Postby slumdog on Tue 9/Jul/13 9:25am

Is it possible? What is required? .

I am aware of requiring the perfect right chain length on a vertical drop frame, but thinking a little sag isn't going to cause an issue if it is run as SS.

for my commuter, current rims are shithouse, and attracted to low price and low maintenance. Chur.

Pulling your frame in from 130 or 135mm to 120mm (I presume? 100mm is a front hub width) isn't good for the life of your seat and/or chainstays - it will stress them badly.

Put a longer axle in it and space the hub out? Or is that poop for the hub somehow?

Not if you have the right axle...chainline will be a bit suss though.

yeah thats do-able but will have issues with chainline. If you really want good ss/fuxienuss on a vert drop bike get a one industries eno hub (not cheap but)

Could use a standard disc hub, put a SS conversion kit on the freehub side, and a 6 bolt cog (tommycog?) on the disc side.

Doesn't solve the tension issue though. And don't run too much sag if you're going fixxed, or you will be :-D

Thanks heaps guys! Yeah sorry 120mm. Is it likely the axle on my current wheelset, the rest of which will get binned, would be a transferrable donor?

Looking at this pic:

If the threads are the same, with added spacers on the old 130mm axle, I should be able to take out the 120mm solid axle, and thread the 130mm through the new cones, space it up with additional nuts on either side of the axle so the chainline is mint, and roll?

I'm not above ghettoing and leaving the derailleur on to hold the chain in place...

Opinions appreciated.

you'll never get the chainline even remotely right - better to get a conventional cassette hub and use a conversion kit with adjustable chainline (surly or a clone)

I have this setup on my singlespeed, standard freehub with singlespeed cog.

And for added ghettoness, I discovered a while ago that spacers made from 40mm electrical conduit fits nicely on a shimano freehub :D

Should be easy as.
Get a 130mm axle and some spacers.
You should be able to get the chainline perfect by playing with what spacers are on on what side of hub.
If you end up moving the hub left or right of it's original centreline you will need to re-dish the rim a bit. I've done a couple of commuter wheels like that.
