The ICE Over/Under Idler Kit replaces the existing idler on your ICE T and lets you remove all of the chaintube. By holding the Over/Under Idler in place with a Clamp-On Idler Mount, the chain makes it past the pivot point avoiding any undue contact. And routing the return side chain up and over keeps it controlled and quiet.
Note: The chain rerouting done by this kit reduces the ground clearance of the trike by about 50mm (2"). If this is a concern to you, we recommend you get our ICE Power Idler Kit, which mounts to the original idler mount.
Since the vertical position of the power side chainline changes with this kit, you have to be aware of potential effects on the suspension. To reduce "pogo," or pedaling induced suspension bobbing, it's important the power side of the chain is nearly in line with the rear suspension pivot. If the chain goes too high or too low, pedalling will pull the rear swingarm in and make the trike bob up and down. Since the vertical position of the chain relative to the pivot depends on a number of factors, we want to be sure that people understand how to know if the chainline is right or not.
Basically, the Clamp-On Idler Mount moves the power side chainline down. This means that you need to be able to adjust your suspension so that the rear swingarm swings up more, moving the pivot down to meet the chainline. The amount of pivot movement required, assuming you already have the suspension adjusted correctly, is about 1" to 1.5". To check your suspension adjustment, shift into the middle cog in back. Sit on the trike, put gentle pressure on the cranks, and have someone sight horizontally into the pivot. The chain should ideally be within 1/2" up or down from the pivot. If you can then adjust the suspension so the chain is 1" to 1.5" too high, you can use our idler kit without any pogo. If you have any questions, please send us an email. We'll be happy to walk through the whole process with you.
