So, I'm building up an FF29 for general fun and also to use on the upcoming Corrieyairack challenge, which is a mix of road and off road sections. You are allowed to switch wheels (or just tyres) before the 38 mile road section, which seems like an eminently sensibly idea, but I only have one set of 29er wheels. Actually I have no sets at the moment, due to a problem with delivery of my Hope/Arch 29er hoops, which CRC seem to be taking an age to sort. But that's a different story.
So, what to do? Buying a new set of wheels for one event would be crazy even for me. Buying a second hand set then flogging them afterwards would be fine, but I'd need to find a 20mm front and QR rear, which isn't too common.
Alternatively I could just ride the road section on 26" wheels. I have a set of 26" Hope hoops and some 26" slick tyres. It looks as though the BB height would drop to around 12", which is low but probably manageable for a one off ride.
Finally, for the cost of some spokes and a lot of faffing around I could take the 26" Flow rims off my 26" Hope hoops and stick on some Open Pro rims (that I have laying around), then run those with proper road tyres.
Or, is there some other option I haven't considered?
