SickBiker, December 15, 2017 in cranksets, bottom brackets
Deput post - Hello!!
Thanks for the video - I watched with interest but length is a factor nobody seems to commit to - perhaps a good video topic I am sure several struggle with this!
I am building an XC bike for my 11yo girl from new and as-new re-purposed parts, and my plans are for
TWITTER frame (26 or 27.5 compatible), bottom bracket width is 68mm, threaded
MANITOU R7 fork
SLX 1x11 (11-42) / SLX shifter and mech
26" Shimano M15 wheels (for now) Ardent/Ikon
Shimano M395 brakes
Basic velo saddle
all above fixed
Variables are the crank (choice here) and bottom bracket (yet to buy);
Shimano Octolink (3x stripped and given a 34t or 36t ali single ring) - this needs an octolink BB
Truvative 1x (steel 38t removed, 34tor 36t ali single ring) - this needs a square taper BB
Finding the balance in theory for the correct BB lengths has me concerned - as real low gears are likely to be rarely used but irritating if slipping off back-pedaling, high gears more likely to be used (9/10/11) on trips. Use for the bike would be cycle paths, gentle trails, some climbs, much flat as I am trying to build my youngest daughter's interest in cycling!
Personally tending towards octo/113mm, but inexperienced with 1x. Any experienced tips welcome!
Hopeful - Graz
btw - this will replace a small frame GT Avalanche 2 (14kg), sweet child bike but heavy...

I would start with the chainrings, Graz. I've been riding the 32T chainrings with 10-50T cassette so far. Are you sure 1x drivetrain with 34 or 36T will be OK for you daughter? Otherwise, the Octalink should be a bit lighter and just more up-to-date BB.
