Can you buy an axle to bolt two square taper crank arms on to so that they can be used in an external bottom bracket. Is it a Stupid idea?
No.
thanks for the giggle tho.
BB cups and cranks woudl foul.
eh? I'm trying to picture this? Basically welding a square axel to to chainset, then filling out the space left where a round one would go?
Why in gods name would you want to?
Is it a Stupid idea?
Yes 🙂
It's an original stupid idea, if that helps at all.
Like an middleburn x-type but with bolts on either ends
Why would you want an external BB? There are some advantages but arguably more to square taper.
Why not just buy a Shimano un54?
In all honesty I cannot tell the difference other than that my pedals do not spin freely with the external BB and they wear out much sooner. On the plus side they're a bit lighter.
+1 gingerss. Shimano UN54 will often outlast the frames on which they're used and cost beer money to replace if they fail.
