RANS Rocket/VRex Rear Idler Kit

13 reviews
SKU: IDK176.1
£66.00

The RANS Rocket/VRex Rear Idler Kit is a serious upgrade to your stock system. With custom idler brackets and a Power Idler, you won't believe how much smoother and quieter your bike will be until you ride with this kit. Easy to install, easier to enjoy! Works well with the RANS Rocket/VRex Rear Idler Kit.

Note: On older bikes with the square seat channel, you may need to trim the excess length from the right side seat clamp L bracket. Since our idlers are larger for greater efficiency, this raises the chainline and may produce rubbing of the chain on the right side L bracket unless it is shortened. Rad-Loc seat clamp bikes are OK.

20 year old VRex

The old idler was worn through. This was an easy repair and looks great.

Easy to install

It was pretty easy to install and came with all the hardware needed. I think I gained 1mph using this vs the stock chain idler (a rubber roller).

Rans Rocket / v Rex Rear Idler kit.

The new Idler center wheel is much larger than the one it replaces and this caused the chain to rub against the bolt that holds the seat in places. We fixed this problem by adding 6 or 7 washers that pushed the Idler centre wheel that supports the chain away from the bike frame. And the chain no longer is in contact with seat lock bolt. This solution could help other Rocket owners. The new Idler is a little noisier than the old one but not too much of as issue.

V-Rex Rear Idler Kit - Replacement for missing stock idler wheel.

This was a simple installation for my earlier V-Rex. Possible interference with the seat retainer, mentioned on the TerraCycle website, was not a problem. This assembly was a replacement for the missing stock RANS idler wheel. I decided to spring for the Idler Kit because I believe if will improve rear derailleur shifting. The stock idler wheel is of much smaller diameter and does not have any teeth.
