Live 2 Ride
So bear with me on this post, I know it's not quite mountain bike related, but it's related to mountain biking gear. Picked up an old 2001 BikeE the other week. It came with the old GripShift 3.0 shifters and SRAM ESP rear derailleur. The shifters are 20 years old, no life left in them, and SRAM doesn't make the parts for them anymore. Same story with the RD. So I put some modern 3X7 GripShift shifters on the bike due to a cramped cockpit along with a Shimano Altus RD. Now it refuses to shift. The only thing I didn't change was the housing, the 7 speed cassette, and the chain. The bike has low miles so I didn't think it would be an issue. Is there such a thing as a bike that really needs SRAM RD in order to shift right? I've been wrenching on bikes for years and even worked at a bike shop when I was younger and this one has me stumped.
