Been entered for his DofE and apparently taking bike out is a thing (or somethibg like that). Allen used it with 29er guise but...
Needed
Wheels: prefer some 650B but will accept 29er rims aswell
Front fork: prefer a boost (tapered obviously

Rubber: I think I got some 650b semi fat tyres but if it turns out to be 29er then I might need what you got..
Bars and Stem: I might have or might not. Need it pretty short and economical (prefer not to have OnOne but dont wanna spend an arm
Gearing: cassette (though I'll probs get this new with a chain); cranks; shifters; rear mech (hopefullywe will get some 1+ system going on there. Prefer Shimano please
Saddle and post
