    Shimano m988 lever not compatible with I-spec

    Shimano m988 lever not compatible with I-spec-image.jpg

    I bought the shimano m988 lever left and right. The left lever is fully compatible with my xtr m980 shifter I-spec, while the right lever shown above is not compatible with I-spec.

    I checked shimano website, both left and right must be fully compatible with I-spec. Is this a manufacturing error?

    Did you buy it off one off those no name cheap Ebay sellers where the chance of it being a copy are pretty high?

    lol m988 lever copy that would be one hell of a fake to attempt.

    more likely you got some OEM part...?

    I've seen a lot more complicated fakes than a Shimano brake lever.

    I believe CRC sells a lot of OEM parts. Sometimes they are a little vague on their description.

    I've been searching in google if there is difference between oem and non-oem m988. Both states are fully compatible with I-spec. In Crc website they described that this is compatible with I-spec as well. It's just weird both lever arrive and the left lever is compatible with I-spec while the right it isn't... This annoying.... If i return this to tome I need to wait 6 weeks before I could get the new one. So meaning 6 weeks without riding my mountain bike... I won't able to do that because 3 to 4 time a week I ride my bike.

    Seems odd. My stock TBc levers which you'd think are OEM if Shimano has an OEM version are ISpec compatible.

    The lever shown above is the new I-spec type B, for 2014. Not compatible with the earlier version.

    I just installed a set of 2014 XT's BR-M785 I-spec type B - looks exactly the same.

    Do they offer any more or less adjustment than the original type?

    The shifter is still in a fixed position on the brake lever clamp. You can not rotate it to adjust it to your comfort. Standard was pretty good for me though

    Can you please post a photo of your lever.

    I got the xtr m980 shifter 2012. It should be compatible with I-spec even with the new ones?

    He is trying to tell you no, it's not backwards compatible.

    The image in the link above shows all :

    These combinations will work :

    - Old levers with old shifters
    - Old levers with new shifters
    - New levers with new shifters

    This combination won't work :
    - New levers with old shifters

    As the image shows, with the new type B brakes there are two type of 'nuts' included for fitting the b-type shifters.
