Sunrace RD-M10 Rear Derailleur Friction Long w/Hgr

The rear long-cage SIMPLEX derailleur on our old Peugeot road bike snapped at the tab that holds the cable. I looked everywhere for information on replacement and came-up empty. SIMPLEX doesn't appear to exist any more though some short-cage derailleurs are still around but expensive. Looked at possible Shimano options but they didn't seem right and not a particular good visual match to the SIMPLEX. This SUNRACE mimics the original Simplex in appearance and is a good match. It bolted into the Peugeot frame identically to the SIMPLEX like it was made for it. The Simplex only had one retainer. To avoid taking the chain apart to fit it in the cage (under the retainer) I removed the cog which is mounted a screw to get the chain out. The Sunrace has 2 retainers so I had to take out both cogs to route the chain through the cage (this takes one side off the end arm but doesn't release any springs). I then reset the cogs for the chain to run the proper way. Its a bit fiddly feeding the bolts through the cogs but I didn't have a chain tool and I'm not sure this took any longer than it would have to take the chain apart etc. The bolts seemed to be metric. After I put it in and reconnected the old cable taut it was a pleasant and unexpected surprise to find that it required no adjustment out of the bag. It's as good or better than the one it replaced. Fit like a charm. Will have to see how it goes but it appears well-made.;

Great producing. Usually I only buy from prime sellers but this time I bought it from this seller and have to say fast shipping (1day) and great rear derailleur for your older or new bike.;

If you have a really old bicycle with an old friction shifter system where you need an inexpensive rear derailleur you should consider this one. It shifts to 28 teeth cog it's designed to shift up to 7 speeds and works pretty well for the price of 3 cups of coffee with delivery. Installed it on 1970s bicycle that have this part missing and went to town. Delivery was a bit delayed due to a severe weather but Amazon and seller made communication very clear and it arrived pretty fast.;

It did fit my son's bike.;

Affordable and functional. Works well with a friction shifter;
