This may seem a little strange, but I was wondering, how I could build up a cheap TT and Tri bike. I started thinking about cheap aluminum frames, so to ebay I went and found these, its a track frame, but can road wheels with normal skewers be put on the rear dropouts, as they are nothing like my current road bikes drop outs?

secondly, with having a 10 speed road wheel on a single speed bike, is this possible? can i just have a 10 speed chain on this bike, and just make sure the chain is sittin in the sprocket i want when putting the wheel into this frame?

Track frames don't have derailleur hangers, shift cable bosses, brake cable guides, brake mounts , fd mount etc ...

The rear dropouts will be spaced for a track hub (120mm) and not a road hub (130mm). That's a big gap to stretch, even for a steel frame. Definitely wouldn't suggest it.

I was thinking of running it single speed, but have the option of just using my road wheels, so i cud select a gear to put the chain around, if you's know what i mean, but since the rear drop outs arent going to work, i may put this idea to rest :/
thanks for the input all the same

The front wheel ought to work fine, but you may want to get a rear hub with 120mm spacing to fit the frame. I don't know of any 120mm OLD hubs designed for cassettes, so you'll likely need to run a freewheel (single or multi-cog, up to 6 cogs with "Ultra" spacing), fixed gear, or internal hub gear.

ridiculously overbuilt.That seems like put togheter for 500lb rider

take a look at Ribble they have a cheap TT frame. https://www.ribblecycles.co.uk/sp/roa...me/RIBBFRAT600

You could probably ride a TT on a single speed track bike.

But you will discover soon enough building a cheap bike can be more expensive on the long run than buyin the correct bike. I did, built, painted, an old bike that looked really nice, spent around 600 on a 300 bike. I did learn a lot but $$$ wise its not worth in most cases

this may be the best option, and could save alot of hassel compared to a track frame , thanks for the input

Or this...
