So, I found a frame near one of the charity clothes containers. It's from a Focus Black Raider LTD size M. I'm not sure about the year tho.

How to find out the size of the wheels only from the frame ?

I googled this bike model, and found 99% 26" wheels, but when I put the 'new' 26" back wheel, the brake mounting points are too low, almost on the level of the rim.

The parts I bought 2nd hand pretty cheap.
26" alu. back wheel, it was used with the original bike. With Shimano 14-34 Thread-on 7-speed Freewheel (I think).

Also, is the Shimano Tourney Megarange back derailleur any good ? The front one is Shimano Deore, the shifters are Shimano REVO, altho I don't like them very much. Might change them for the stock Shimano XT/LT at some point.

I bought some ZOOM front fork, but it's sadly only for 26" bikes. I might sell it, and some of the other unused parts, or barter them, or install what I can on my/my wife's 26" 90's rigid MTB.

The pedals fit on the cranks. The seat almost fits on the seat tube's clamp, but I'll leave that for last.

Also, any other recomendations for cheap new/used parts I'd want to look for.

I can assemble everything myself, just not sure about the compatiability between everything. The other thing I'm contemplating is going 1x10 or 1x7. I barely use the front derailleur.


Thanks,
G
