hi new to all this and as you may tell i have a giant boulder 1995. its in reasonable good condition but would like to replace a few bits where is the best place to go for derailluers and cranks that are original to the bike
If yours is steel, it would be this spec.
I know that at some point there was an aluminium version of the Boulder too. I owned one of those in the late 90s.
As for where to get the parts, that would be either in the "For Sale" section here or on eBay.
