I needed the best idlers for my streamliner if I'm going to break the 78.1 mph American speed record.

My old idler started making noise so after replacing the bearing with no effect I purchased a new one, but it makes the same noise.

Work of art really, spins smooth and quiet, and thats with the ABEC 7 bearings ... ceramic would be overkill for out timing chain tensioner.

I've been using Terracycle idlers for about 8 years now. Never had one fail and they have lasted much longer then the OEM idlers they replaced. The chain lasts longer too.

The item was really nice, but it did not work for my needs so I had to return it and order another part specific for my bicycle

Works as advertised. Didn’t realize the tortured shipping route it took from the USA.

Adding the new Sport return idler really benefited in silencing the ride.. Along with the new chain tubes and floating tube holder, all I hear now are the wheels riding over the leaves left behind by our winter.. No more mechanical or chain noises.. Thank you Aaron and Pat for all your help and suggestions..

Old power idler was 8 years old. New one much more quiet and spun more freely.
