Advice Needed, Bb/crank/freewheel Issue

[lego]

Bike monty 221, std BB 124mm x 68mm, Zoo cranks, Zoo Bash, ACS freewheel.

The ACS catches the crank cup on the drive side with the teeth thats used to screw the ACS onto the crank arm.

A.) Will a different freewheel like a tensile solve this?

B.) Go for the 128mm x 68mm BB

C.) Do both the ACS is shit.

Thanks for looking

Just change the freewheel, I'm not sure about a tensile, but a try-all/monty should do the trick.

The shorter the BB the better because the chain line will be better, which is always a good thing. Most mods use 110mm hubs and 128mm BBs, which leads to a terrible chain line to say the least.

However, it'll give him 2mm more clearance (potentially) with his freewheel, which is all good. However, I'd reckon going for both options would be a good idea - Tensiles are really nice freewheels, and with a 128mm BB it definitely won't rub. Tensiles are a mm or 2 narrower than ACS's, so it may work with the current BB, so you could always get that then add the BB in as well if it's still too short

Thanks for the replies guys, I`ll let you know what works

Tensile sorted it no more rubbing and using the STD BB.
