What’s wrong with this BB and/or crank?
Picked up a Trek Alpha 1.5 beater bike to use with my Cycleops trainer. Bike pedals fine. Was lubing my spd pedals and noticed the gap between the crank arm and bottom bracket. Is the arm just not tightened down enough…or is there a collar or something missing?
I just ordered a crank puller and bottom bracket tool. Crank is an FSA Vero square crank.

If the crank isn't loose, don't do anything. It's normal to see a gap with square-taper cranks. Old-school square-taper cranks showed a lot of spindle.

it’s def not loose. Tried to get crank loose, but zero luck…that’s why I ordered a crank puller. So dirt etc getting in that gap won’t affect BB bearings?

That’s good news. Well, now I’ll have tools to service/replace the BB cartridge if/when it’s necessary. Is a cartridge setup serviceable(regreasing etc)….or do you just replace them when they start to fail?
