I can confirm this fits with T47 internal BB (Trek)

The instructions call for 2mm spacer on either side, based on a BB width of 91.5mm. My BB measured 90.5mm, so added an extra 0.5mm spacer each side. Q factor seems quite wide, I could probably remove or reduce the thickness of some of the spacers, especially on the non-drive side. PM is very close to the BB shell frame though.

Easy to fit, no issues with pedal threads as reported by others.

Weight 498g for 165mm length (crank and PM only, excl. chainrings, chainring bolts etc).

Maiden voyage to come this evening...
