But I did build her a fatbike in my "spare" time (ie, burning the midnight oil) and it's going to be fun, I hope. We live in a place with a LOT of fatbike opportunities... might as well take advantage!
|You could put a Bluto on, but you'd have to accessorize with a DT protector!|
-63.5cm front center/70 HTA/90mm trail
-57cm ETT (curved down for a little extra room when her foot postholes)
-30.5cm/12" BB height
-41.5cm/16.3" (yup) chainstays
-170mm/QR in the rear and 135/QR on the fork
-Clearance for any 4" tire and some 4.5s (115mm of space @345mm from the axle), but not Bud/Lou type stuff
-Single ring only, and max 28t. You pay a price for that short stay/big clearance combo.
-100mm shell/66mm chainline. I intended to do 83mm but we decided she'd be ok on the wider Q factor and went for the shorter stays/more clearance options available with 100mm.
-Frame can take an 80/100mm Bluto, but doesn't have enough clearance for the adjuster knobs (so I'd add some kind of DT protector if Sarah ever wanted to go that route)
In essence, I wanted Sarah to have a fatbike that rode a lot like her XC bike and didn't feel like a big heavy slug on the trails. We won't be riding down frozen riverbeds or through the deep woods off trail (and Sarah doesn't weigh that much, so she'll get plenty of float from 4" tires), so 170mm spacing and all the limitations that come with that are ok. It'll initially be built up with Nates or Knards on some new Hugo rims (if they ever show up!) Should be a blast on the 100+ miles of fatbikeable trails here in PC.
