    Idler pulley

    I have installed the sports +15 tooth idler pulley and it has smoothed out the entire drive. It’s wonderful.

    T-Cycle SportPlus 15 Tooth Power Idler Review

    Nothing else worked.

    My experiment has nothing to do with trikes, or normal chain management. I have an E bike that puts a reverse load onto the chain under coasting conditions. It takes a moment for the derailer to pull the slack out. Probably because I zip tied my cassette to the hub to use the freewheel in the mid drive motor. Everything else I tried vibrated from running on the outside of the chain. Any friction there made things worse. This allows me to run it on the chain full time and guide the chain onto the chain ring at any angle, vertical or lateral. The 2 bearing design, and their 5 hole adjustable bracket got this working with my 50t chain ring. I don't have the equipment to build stuff like this. These guys have done it already. In my case I also needed the offset clamp of the 5 hole bracket to clear a torque arm on my seat post. That is a very versatile bracket. Since I mentioned the zip tie mod I must warn anyone who might try this to use 1 or 2 of the smallest zip ties. Any chain suck event will break them and the bike will return to normal operation. It allows you to shift a derailer w/o pedaling. Shimano actually offered this many years ago with the freewheel in the cranks. It can still be found aftermarket. A chain guide is always needed.

    I was becoming annoyed with the chainline noise my trike was making. Nothing terrible but annoying after a few minutes of riding. I changed the stock idler to the SportPlus and the chain tubes to new flared tubes. What a difference! Much quieter. The SportPlus idler and flared tubes make trike riding much more enjoyable.

    Pulley upgrade

    Product selection, online store and quality of products were excellent. Very responsive to my questions and honest communication about the delay on one of the pulleys. Very much appreciated. I will definitely be back!

    A saga that ended well

    To cut a long story short I replaced the existing idler on my ICE Adventure that was noisy and rough with this superior item. The difference can be measured in decibels and smoothness. A tad expensive when shipped to Canada but hey, it's only money.
