Hi, first post here.
After looking for something to take up some winter free time, I decided to rehab my old road bike, an old Panasonic DX4000 with all Shimano 600EX (6207) components, right down to the headset and pedals. I hunted down a complete new lot of parts on eBay and at a few local shops, had the rear wheels rebuilt on new hubs, with new spokes and two new old stock Araya 20A rims, and installed the new BB, new crankset, and new Shimano 600EX freewheel, and a new silver Shimano UG chain, which matches the UG type rear cogs.
The bike rode ok before but was badly worn, it had thousands of hard miles, but the chain ran quiet. The current set up is the same other than the chain, the old chain was made by Sedis, and the old freewheel was Suntour 888, it was the chain and freewheel the shop use when it was last upgraded back in the early 90's. The chainline hasn't changed, both freewheels have the same cogs, both are 14-24 freewheels, and all other parts are number for number, exactly as it was before. Now I get a chain noise that sounds like it's dragging between shifts in all gears. It's worse in the highest range. Even on the middle cogs, where the chain is dead straight it makes noise, almost as if the chain don't match the teeth right.
I opted for the Shimano chain since I figured it would be the best match for their twisted tooth style freewheel.
I've never run a Shimano freewheel or UG chain, do these maybe get better with use?
It don't skip and it changes gears fine on the road. It just sounds bad. It sounds as if the chain is hitting on the side or something. The chain has flared inner links, and its noticeably wider than the old chain. This is a 12 speed bike, with a 6 speed freewheel, the rear hubs are 126mm spaced, and the crank axle is 116mm and came with the crankset. It's identical to what it had. I tried the old chain but its stretched bad and skips under load on the new freewheel. The old freewheel had several cogs worn too bad to use as well. The frame is also in perfect alignment, a local bike shop checked that first off but couldn't find why the chain makes so much noise.
Did old UG chain run noisy?
Should I hunt down a different freewheel and chain?
