13 reviews
SKU: IDL037.1
  • Made from Delrin
  • Rubber O-Ring keeps chain centered
  • Bearing with 6mm ID
  • 1.75in (44.5mm) outer diameter

This is the idler we use on our chain tensioners. They are handy in other return side applications too. For example, older Vision bikes used something close to this for return chain management and these idlers can be used as a replacement.

Nice Inexpensive part.

I bought several T cycle idlers for a chain guide project on a 1500W cross chained E bike. I stuck an 8mm bearing in it. So no warranty from the start. It's a nice design, well built but not what was needed for this experiment. The project was a total success with some of their stronger parts. Maybe they could offer an 8mm bearing version so it will fit some of their other mounts.

Fit perfectly, better than original.

Replaced 2 chain idler roller guides on my venerable old Vision R50. The replacements fit nicely and we're easy to install. Design and materials look to be better than the originals.

Delrin idler for my Volae

Superb. The quality of the idler wheel and bearings is top notch and noticeably superior to the original.

Perfect Fit For A Vision VR54

I have a VR54 with the instant adjust chain tensioner with 2 idlers and an additional idler under the seat. I purchased 3 idlers to replace them all. Going into this blind I figured for sure I would need additional hardware. Surprisingly nothing was needed hardware wise on the instant adjust. For the underseat idler I set aside the nylon spacer that was OEM and went with a slightly smaller (length) nylon spacer that I had on hand. I would like to commend and say thanks to T-Cycle for the quick turnaround. I had these items in my hands 48hrs after ordering all the way from the west coast to here in Va Beach.
