Why haven't Shimano or SRAM internal hubs had as many gears (or as much range) as Rohloff?

There are a couple of likely reasons IMO. First, Shimano don't make anything like a Rolhoff and that's intentional. Shimano market strategy is all about mass sales to bike manufacturers, and ...

Why haven't Shimano or SRAM internal hubs had as many gears (or as much range) as Rohloff?

Making an internally geared hub with 14 speeds that is reliable is prohibitively expensive. A Rohloff hub alone costs than most people's bicycle. It is a hard sell to most people except for a few, ...

Cadence: Belt drives + Nexus 11 hubs

A Gates drive belt uses an 11mm pitch between teeth. A conventional bike chain is 1/2 inch or about 12.7mm. The upshot is that for the same tooth count, a drive belt component will be slightly ...

Can I fit a modern internally geared hub on an old bike ?

While you probably could cold set it, the Sturmey-Archer XRF-8 is available in a version with 120mm OLN dimension. (And you almost certainly can fit a modern bottom bracket. Worst case, have the ...

How to prevent Alfine 8 from "skipping"/"slipping under load?

I have an Alfine 11 (so very similar) and I had the hub replaced 2 times on warranty because of this skipping problem. The third one is fine so far (~15000km on it). So based on my experience: Have ...

Anti-rotation washers (non-turn) washers in non-parallel dropouts?

The torque that the axle sees relative to the frame can happen in both directions as gears change. For example in the classic Sturmey Archer 3 speed, it's the second gear that is neutral and does not ...

Wear on an IGH by pre-selecting gear under power

Shimano IGH use springs to move cogs away from the cable pull, and what's happening is that lateral friction between the engaged cogs inside the hub is too great for the spring to overcome. This is ...

Lubricating an alfine 11 IGH hub

As far as I've discovered, the alfine oil is the same stuff in both the small and large jars. So the large jar makes sense for high-mileage gearboxes, but you don't "break even" till you're doing ...

Anti-rotation washers (non-turn) washers in non-parallel dropouts?

I think you need to ask your frame manufacturer if the dropout can handle the torque with only anti-rotation washers or if you need a torque arm. Below I derive the formula for the torque (verified, ...

Alfine crank 1x9 setup, spacer issue

I think the problem is that you have a crank with a 'mountain' length spindle, but a 'road' Hollowtech external bottom bracket. Hollowtech 'road' BBs only fit a 68mm shell. 'Mountain' BBs fit both 68 ...

Internal friction in new Alfine 11 S7001-11

Shimano Alfine 8, properly adjusted, doesn't downshift from 5 to 4

I had the same issue after a few years. The teeth inside the shifter were worn out and i had to buy a new one. Grease doesn’t really help since it’s only one spot.

Cadence: Belt drives + Nexus 11 hubs

A gear ratio is a gear ratio. It doesn’t matter if the gears are connected by a chain, a belt, meshing with one another or anything else. All that matters is the ratio of the number of teeth.
