Customer review of this product:

StarStarStarStarStar Great Value for Fat Bike-specific parts

Product: Origin8 100x137.5mm Square Taper Bottom Bracket
Ownership: a few months
Tech Knowledge: somewhat high


This a first-rate assembly as far as I can see with well-formed threads on both bearing holders while the bearings themselves seem to be excellent quality



Other Thoughts

Fat tire bikes naturally have a big "Q-factor", the spacing between the pedals. My OEM bottom bracket set had a huge "Q". I tried the Origin8 164mm assembly and it worked OK but there seemed to be enough overhang that the 137mm might work. Luckily the pricepoint is low enough that I took a chance. after assemble with a 2.5mm spacer on the drive side I had a hair of clearance between the crank and the bearing cup on the non-drive side, and half-a-hair between the chain and tire in bottom gear, so I've got the least "Q" possible with standard MTB cranks
