If I get a track frame can I put parts from a hybrid on it?

monkeydan

Sup,

I don't know much about bikes but I know what I like, and that is single speed bikes. I miss mine and am thinking about trying to put one together.

At the moment I have an old Trek 7.3FX. If I buy a new frameset, what parts from my Trek would I be able to use on the new frame? I have spent literally minutes searching for answers but pretty much everything I can find is about converting an old bike in its entirety to a fixie / SS, not about sticking old parts on a new frame.

This has made me very confused so I'm trying to figure out what bits I would need to get a decent bike together?

I'm looking at the Surly Steamroller or Genesis Flyer framesets, could I use the wheels, brakes, seatpost, etc. from my Trek? I would be looking at getting drop handlebars so would need new brake levers.

Bear in mind I am probably the least practical person in the world so this may not be a good idea but any advice would be much appreciated.

Cheers

Dan

Wheels: Probably not, as the rear hub would be too wide, the front would fit.
Brakes: Nope, they look like v-brakes, roadie brakes would be required.
Seatpost: Depends on the thickness, but possibly.

This will likely be most people's response when reading this.



I know I've done it before, but it's still funny

I think you're right - the Trek is 130mm and it looks like the Surly frame is 120mm. If I got a new hub could I still use the same rim? What about spokes?

They are v-brakes on the Trek, roadie brakes are caliper brakes?

Rick, thanks, I'm at work so will watch the link later. I appreciate you guys taking the time to help me out.

I think you will find this a nightmare:

rear wheel needs rebuilding with a new hub - probably new spokes, more than likely.
Buy caliper brakes
Also, there is the faff of stripping down your crankset and getting chainring bolts - always looks messy.

In all honesty, allot of work, pain and probably money spent on parts to convert.

What I would do is:

take gears off trek, get a singlespeed tensioner kit and convert the rear hub - remove derailleur, add tensioner, strip down chainset to single ring.

Cost is just the SS kit.

I suspect the trek would have 135mm spacing, that's the MTB standard. The road frames would have 130mm. It's not a massive difference, some people just bend a steel frame a little to accommodate, an old bike of mine had that done, the wheel was never central.

If the hub you got was the same-ish flange height, you *may* get away with re-using the spokes, depending on length. If you're happy to rebuild a wheel, then a new hub would probably sort it. Your rims probably wouldn't be right for skinny tyres, though, so there may be problems with fork clearance.

V-brakes have a different pull to road brakes, so road levers wouldn't pull them enough, they probably wouldn't fit to your frame either, as road frames only have drillings for caliper brakes.

Assuming the current rear wheel is built on a dished hub, those spokes might not be much use on a symmetrical one.

The Trek is a hybrid so I think it's 130mm, it takes 700 x 32C wheels / tyres / whatever the hell that measurement is.

I don't really want to keep the Trek frame though... y'know, steel is real and all that. Plus (sad as it sounds) I don't like the look of chain tensioners. I've also heard they are not very reliable if you decide to go fixed (which I might once I have lost enough weight to get into some skinny jeans).

I might just say f*** it and buy a new bike. Decisions, decisions...

Your best bet would be to tell the other half that the wise bods on here have told you that a new bike would be best, new bikes are always the answer, no matter what the question!
