    Description

    Simply fit this sprocket to your existing 10 speedd cassette, using the clear instructions provided, and say goodbye to your front shift setup. See the compatibility chart here Click here to enlarge Q: Can I use the 40t expander cog with a 36t cassette A: We don't recommend using the 40t expander cog with a 36t cassette. Shift performance will be compromised as the timing will not be correct. Q: Can I use the 42t expander cog on my 34t cassette? A: The 42t expander cog WILL NOT work with 34t max cassettes. A 6 tooth jump is the maximum for good shifts. Q: I have a short cage dérailleur on my bike. Will that work? A: We recommend a medium or long cage dérailleur Q: Why do you only have a 42t expander cog for SRAM cassettes A: The 40t is available only for Shimano as SRAM is not offering a 34t cassette. Q: Is it hard to setup the expander cog? A: It's really not too hard, but you are working at the extreme limits of your rear dérailleur. If you have specific questions about the setup and adjustment, we recommend heading to your local bike shop. Q: I have a really worn drivetrain. Will the expander cog work ok on my bike? A: Old drivetrain components could cause poor shifting performance. We recommend a new chain and a new or well-cared for cassette.

    Rated 4 out of 5 by DDS25 from Good quality for the product Good quality product especially for the price and easy to install. Just could have been packaged a little better to protect it in transit.

    Rated 5 out of 5 by Barns from It's a handy piece of kit but it's a little pricey I like the range that it gives me. I've also used a one-up and it's similarly good. Nothing beats having the full shimano cassette which has the same range now.

    Q & A

    Is the 42t cog compatible with all sram cassetes ?

    Asked by: xico95
    Please refer to the compatibility chart in the product description.

    Can this Expander be used to replace a worn 1st gear on a SRAM XX1 set up

    As the 1st gear on a SRAM XX1 (1x11) cassette is replaceable (SRAM won't let you into this secret as they want you to pay a small fortune for a new cassette. The 1st gear cog on the XX1 cassette is made from a softer Alloy than the other 10 cogs) Can this expander cog be used as a direct replacement "al a Wolf tooth". Will it attach onto the locating lugs on the 2nd gear cog?

    Will this work with a 11t to 36t cassette and also with a triple chainset?

    Asked by: yamyam10
    So long as it's listed in the compatible cassettes: http://s.wiggle.co.uk/images/Extended-Range-Cog-Compatibility_C.jpg It will not work with the 40t well, we advise 42t only with a 36t. You may exceed the derailleurs capacity with a triple set up and this.

    SRAM compatibility

    There are 2 Shimano options and a SRAM XD option. I have a 10 speed SRAM GX mech and 1030 cassette which uses the same driver as Shimano (not XD) so I would assume I'd go for the Shimano option, but will this be compatible with SRAM cassettes as far as shift ramps and things are concerned? Basically will the 42t Shimano option work with SRAM GX?
    Asked by: Peterjq27
    We can confirm the Shimano will be a suitable option We hope this helps!

    Will 42t Shimano cog with SRAM cassette

    I've bought the Shimano 42t but meant to buy the 42 SRAM. I've fitted it to the bike but only just noticed it's the Shimano not the SRAM version. I have not not used it on the bike but have fitted it to the wheel and it looks fine with the spacing etc with the SRAM cassette and fits tight but don't want to ride the bike in case it won't shift properly (and I have to return it). Will it work? Thanks
    Asked by: Brooksymike
    This should work with your set up with no issues at all. I hope this helps.

    Hi would this cassette expander cog work with a 9 speed derailleur (it is 11-36t)

    In theory i would take the 11t cog off and put the 42t one at the back in place of it.
    Asked by: TomBish
    This will not be compatible with the 9 speed set up.
