Questions & Answers (6)

Can this internal gear system support the weight of a 273kg vehicle and function properly?

By Pablo

08 Aug 2024

I need an internal gear hub system that can support between 273kg-300kg without fear of it breaking or not working properly, the hub must have between 3 and 6 gears.

SJS Customer Service:

Sadly we cannot confirm this hub will be compatible with your needs as such systems have never been attempted before, it might be worth looking at the Shimano Nexus system which is quite durable. 08/08/24 SK

Could you let me know which is the right part to add to a wheel build to achieve 135mm OLN?

By Chris

SJS Customer Service:

Altering this hub to a 135old is not advised as the axle will be too short. SK 22/02/24

Complete part list to install

By Héctor

I would like to know if this part number contains all the needed components to install the hub. I mean speed shifter, sprocket and others... If not, please, could you specify the complete list of components (part number) to install this hub?

SJS Customer Service:

Hi, all the parts you have mentioned are included with this item, please see additional images and the product description and linked documents.

Can this be adjusted to fit 120mm?

SJS Customer Service:

Yes you can, as you can simply remove one of the washers to space it down to 120 OLD.

Hi,

The only suitable twist shifter for the S-RF3 hub is the TSS34. This is available on our website and is SJSC part 34810.

Thanks.
