feasibility of fixed-gear to "regular" road bike conversion?

Yo, I have a Pista like everyone else in the world, and the fixed-gear novelty is wearing off a bit. aka I want to look in to converting it to a derailler-equipped freewheel double-braked affair. Will I run in to problems due to the frame's construction viz. the track fork ends, etc?

Sorry btw if this is in the wrong forum.

Sell your fixed and buy another bike. The next poster is going to call you names.

you could probably run an internally geared hub. shimano made some mountain bike hub that the derauiller attached directly too, but i heard they are ****e.

There may be a bolt-on derailleur hanger. But it seems a bit kludgy to me. You could probably find an internal gear hub, maybe a 3 or 5 speed. But by the time you bought that and had the wheel built you'd probably be better off just buying an inexpensive road bike.

Internally geared hub. SRAM makes 7- or 8-speedhubs without coaster brakes, if I remember correctly. You may run into some trouble with cable routing, but it's nothing some zip ties can't fix.

What 5 letter word do you all keep typing that gets censored that ends in e? s-h-i-t-e? It would seem that adjectives used in this part of a phrase generally end in y.

OP- internally geared hubs are cool, but if you just want a road bike get a road bike. IGH are best used for commuters or touring bikes- derailleurs were invented for a reason.

There are some very nice looking derailleur hangers made for track frames by a gentleman in Japan. I'm trying to find a link for you...stay tuned. Running an internal gear hub is another good option.

Converting a geared bike to fixed works because you are removing the parts that you don't want.

Going the other way isn't going to work as well. You're going to need some kind of derailleur hanger, cable housing guides or stops, and maybe someplace to hang brakes. If you have those bits welded or brazed onto the frame, it's going to cost a lot. If you kludge it together with a bolt-on derailleur hanger and zip tie the cable housings to the frame, it's going to be ugly.

Either way, what's the point?

This is incorrect. Keep your Pista and buy another bike. Eventually, the novelty of gears will wear off and you'll want your fixie back. Later, you'll be happy to have both and use them each for the rides they're appropriate for but want a touring/cyclocross/utility/road/mountain/folding bike.

The number of bikes required to be happy is n+1, where n is the number of bikes you actually own.

All the other problems aside,getting a 126 or 130 spaced geared hub into a 120 spaced frame might suck a little...

If he views fixed gear as a novelty, he should sell. Maybe get a lowered Civic...

A Shimano Nexus 3 speed would do the job nicely AND look esthetically well on a track bike (people won't even know you have a geared hub if they don't see the shifter cable or if you don't install it); plus they're quite reliable, keep it lubed well and it can do without a rebuild for a long, long time.

It also doubles as a coaster brake.

I've got a geared, fixed, and freewheeled SS bike. I get bored when i'm only riding one of them for more than a few days.

I really want a cross bike now. its a dangerous cycle.

I've done this same conversion on my Pompino. Aesthetics aside, it's a great idea. The worst thing is going to be spreading the rear triangle. If you don't mind just running a 5 or 6 spd freewheel, you can just find a pre-1970 or so wheel with 120 spacing. You can either run an old school derailleur adaptor claw or you can buy a dropout set for a Santa Cruz Chameleon. I think DMR also sells a set of chain tugs with a hanger on one. Just run full housing zip-tied to the frame. I suspect more people will be doing this as the fixie fad wanes. It seems you can buy a nice steel track frame for alot less than any steel road frame anymore, so it doesn't seem worth it to try to sell and buy another frame.

It is not drilled for a rear brake, but it's not too hard to get around that. Probably less of a hassle than the issues already discussed.

if you ride a geared pista anyone on a fixed gear will make fun of you for being a dropout (pun intended) and roadies will make fun of you for having a worthless setup. they will both be right.

Don't bet on it. Everything is harder to do than you think it's going to be.

Most modern road caliper brakes use a recessed nut. That means that the hole nearest the seat tube needs to be a larger diameter than on the outside. There's not enough clearance to get a regular power drill in there.

To the OP,
I would recommend (like others) to watch your local craigslist for a good fitting road bike from between the late 1970's to the late 1990's. Depending upon your local market you should be able to find something, overhaul it at home, freshen up the tires, brake pads, bar wrap, cables and housings and end up with a decent bike for probably less than the hassle and cost of converting your track bike into a road bike.

But if you're stuck (or stubborn)(or just because you want to do it) then go for it. You could go with an internal geared rear wheel with a coaster brake which would address the rear brake hole issue someone above mentioned about your bike.
Keep in mind what sort of shifters you'll use, brifters, downtube mount, stem mount, bar ends, MTB style twist or thumb shifters, or 3-speed twiddle stick shifters like the old Sturmey-Archer setups.
Lots of options, but the easiest and probably most economical is to find a road bike and store or sell your track bike.

Good luck with whatever you decide.
