hi everyone,
i got a retro raliegh r100 this afternoon and i thought id change the wheels over with another retro raleigh which has 105 hubs and mavic rims (a little worn lol). anyhow when i put the mavics on the rear wheels makes the drivetrain stiffen up if i change up into a smaller cog. the strange thing is when i spin the drivetrain i cannot locate where it is stiffening up. thought it was the chain, then the bottom bracket. maybe its the axle and spacers? of which i tried a few combinations to little effect. i return the original wheel to the r100 and the drivetrain returns to functioning normally.
any help much appreciated in advance.
