Is this the correct place to ask this Mods?
A mate of mine had a crank break the other day. This used to be a thing a long time ago and went away but it seems breakages are more common again from what I've been hearing. Indeed crank sets have been recalled by Shimano et al. What surprised me was that this was becoming a thing again and that my mate says that looking at his breakage there are two pieces of alloy glued/bonded together. So my question is - Why would engineers/manufacturers wish to go down a bonding parts together route, especially in such a stressed part of the machine. AFAIK it's a Shimano crank set and so far no pictures.
