I'm a little confuse. If T-Bolt's frame can only fit in Deore LX's front derailleur, does it mean that I can only change to Shimano groupset regardless of what model (for example: Deore, XTR, or Saint)? Also in between these Shimano components, it can be mix and match right? (for example: Shimano XTR with Saint cranks)

Any good LBS recommended for buying new groupset?
