using a 9 speed crankset on a 7 speed setup
I have a Raleigh M50 mountain bike and the rear derailleur cratered. I purchased a new rear derailleur and while I'm changing this I am thinking about changing the front crankset and deraillleur. I was thinking about upgrading to a Shimano Deore M532 crankset. My bike is a 7 speed, the current BB is a 68x116. I'd also like to replace my front derailleur with a Deore. Later on I would like to replace my rear wheel and cartridge. I was wondering if the M532 would work with my current setup, would it be safe to use a Deore FD? Thanks for any advise..
