Have now ordered two cranksets for this build
White Industries, which has a 94bcd
Shimano XTR FC M900, which hopefully has a 110bcd, which means I should be able to buy a 44t narrow wide for it.
White industries will probably go into the "spare parts" bin.
Other parts ordered for the build from the bay of dreams
Ritchey trail stem + seatpost
Deore Hydros
Halo T2 rims (new tho)
Also obtained a pair of 26er wheels with hope hubs. Will get these dismantled and built up with the T2 rims. Hopefully.
Currently doing my head working out an SS gearing that will require the least outlay to turn into a geared...gearing when the time comes. The small wheels mean that you can get low gears very easily, the tricky part is speccing a big enough chainring that you get a decent top gear.
Assuming the smallest cassette I'm going to find starts at 11? So a 44t chainring will get me 74.7 gear inches. Which seems pretty low? But maybe it's fine for small wheels? According to sheldon thats 20mph at 90rpm, which seems...fine? I should maybe go up to 46t.
Though of course having a massive ring on the front, whilst making it easier to run with gears when the time comes, makes it harder to run SS. What's the largest rear cog I'll be able to find that'll fit on what I assume is a 10 speed shimano freehub? I guess if I can find a 16 that'll put me at 54 gear inches, which seems acceptable for a single speed
