Can I replace the internals of a new hub into the shell of an old one?
21 Feb 2023
I have an old Alfine 11 hub (~2012) that I fear has seen better days. To avoid needing to get a wheel re-built, is it possible to simply replace the internals?
It is possible, Shimano do sell the internals separately, provided the internals are compatible with the shell that will work. SK 21/02/23
I have an Nexus 8 speed hub with disk brake

Can I exchange/fit it with a Shimano Alfine SG-S7001 11 Speed Disc Hub.
Yes, however new shifters, and cassette joint unit is required.

Is this Di2 compatible, and does it have a specific motor unit which is recommended for use with it?
12 Sep 2020
Hello, not for the Di2 hub you MUST use the Di2 hub unit- sjsc code: 37566H36
How low is the lowest gear
04 Jul 2020
Assuming the recommended pedal ring for this hub, how would it's lowest gear compare to a 22 front and 32 back on a MTB?
Please take a look at this website for further info about the Alfine 11 gear ratios

Hope this helps!
Are your pictures right?
27 May 2020
You list four SG S7001 products. 8 and 11 speed. Black and silver. All disk. The pictures show two tapered housings and two stepped. But the shape is not associated with number of speeds, nor even colour. Perhaps one shape is an older model?
Hi, thank you for pointing out our mistake. The black 11 and 8 are reversed. We will correct this. Thanks
