With a CNC-machined 7075 aluminum cog and bearing carrier, fiberglass reinforced nylon 6/6 sideplates, and high performance ABEC-7 bearings, the SportPlus Power Idlers from T-Cycle are the sleek, beautiful, light and quiet must-have upgrade for your chainline.
Only 20° change of direction. Very noisy maybe increase chain tension?
Great technical support in helping me find this idler pulley for a customers Catrike. We will definitely be using T-Cycles services again for our recumbent parts needs.
the Sport Plus 15 Tooth Power Idler is a perfect fit for my electric trike. I had to make a couple of custom spacers to make it wider to be compatible with 410 chain. The bearing is rated at 3500 rpm and if tensile strength of the 7075 alloy sprocket is UN-tempered it is 40,000 psi which is more than enough to handle my 72v 3000w motor. the sport plus should be very durable for my application https://en.wikipedia.org/wiki/7075_aluminium_alloy
