Will this Shimano Ultegra R8000 11-34 Cassette fit Shimano 105?

[r04DiE]

Hello all,

I have Shimano 105 and I would like to buy this rather large casette. Can anybody tell me if there would be any issues in fitting it to my Giant Defy 1 Disc road bike, with Shimano 105?

Happy to elaborate if needs be!

Thanks

It will fit on your wheel, however if the rear mech will accommodate it is down to a number of factors. Have a look at the link below:

Thanks - that looks like exactly the info I needed. I will take a read later. Looks like I have the SGS (long) cage at 86mm centres on the jockey wheel axles.

If your bike has a 11-32 cass currently then it has a long cage and will most likely work with no issues or a B screw adjustment.
