I recently converted my mountain bike from a 2x10 to a 1x10. I have a Shimano XT Hollowtech ii crankset and I like it a lot, but its traditionally a 2 speed crankset. When I'm in my 1st gear on the rear, there is some cross chaining going on and no matter how well I adjust my rear derailleur, if I back pedal a little bit, such as to get my pedals in a good position to get on the bike and take off, the chain will drop into the 2nd gear cog. To remedy this, I have found two potential solutions.
Buy a new 1x10 speed crankset such as the Shimano Zee. This obviously is a more expensive option.
Get some longer chain ring bolts and some chain ring spacers.
My question is will option #2 be sufficient for mountain biking? I wasn't sure if adding spacers may somehow cause some sort of vulnerability in the crankset by possibly not allowing as much force or tension on the pedals? Or am I delusional and it does nothing to cause any additional weakness or vulnerability to the crankset? If spacers are completely safe for my application, this would be the best option.
