Revamping an old trek

fearnsy

Hi all, I have an old trek 930 singletrack (rigid), it has shimano stx gearing which runs very smooth, however I was just wondering would it be possible to transfer the majority of the bike (except forks and frame) over to a new frame, possibly an on-one scandal? I was just wondering as I was gonna stick some slicks on it and use it for some longer distance rides.

Your main issue will probably be that the headset, stem, seatpost and bottom bracket will need to be replaced.

I'm guessing that your old Trek has an old-style threaded headset and it's unlikely that the seatpost and bottom bracket would be of the exact same size. It's also my experience that a really old headset and BB would disintegrate on dismantling them anyway!

The rest will almost certainly transfer. A good new set of cables, grips, brake blocks and tyres would make the world of difference.

So in summary, you'd need:

- Aheadset (£15)
- Ahead stem (£15)
- Bottom bracket (£15)
- Seatpost (£15)
- Plus optional grips, brake blocks, cables, tyres etc (£50+)

You're probably looking at least £110 plus the new frame...

Ah right, thanks very much for the reply, so all the gearing would be fine?

Yep, although you can add to that list a new front mech, I don't know the seat tube diameter of the ScandAl, but I suspect it's 31.8 or 34.9. IIRC the Treks are 28.6.

Cable pull may be different too.

Why not just pick up some bargains for a new drivetrain on here? Even if the parts still run efficiently would be nice having new kit on a new frame.

also scandals are disc only.

My Carbon Genius started life as a Marin Palisades trail from the early 90's!

Yeah thanks,
Think this will become my ongoing build for the next 6 months or so (I'm only 16).
Getting a vengeance ultimate next week and blinging it up, then might go for a scandal frame with carbon forks and trust try and make it light and quick really.
