What you don't see is that you have no problem with your modification, (the bb spacer), but anybody else's is encouraging the abuse of their equippment.
Just remember, I said up front DON'T do it!! But, a BB spacer,if he insists is a cheap,simple and acceptable way way to do it.It's the answer when short stays cause chainring rub when in the small ring and small cogs other than the smallest. So you have to make a minor FD adjustment.Big deal. I have yet to see a FD that didn't have enough travel to handle the additional throw required by a 1 or possibly 2mm spacer. But as already stated:Best answer is DON'T do it.There is absolutely no need.
