Please help! I've recently changed my jockey wheels to tacx 10 tooth appropriate for shimano 8 speed cassettes and derailure. Seems to be running smooth upto 14-16 where it becomes noisy and feels sluggish when pedalling. I think this is because the jockey wheels that where on was 11 tooth shimano. Will removing a chain link remedy this? Or do I just get the 11 tooth version of the jockey wheel? Your insights will be greatly appreciated!
