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

Why can't the Schlumpf Mountain Drive be used along with the 14-speed Rohloff?

If you use the Rohloff Speedhub, then you should use the Schlumpf Speed Drive (not the Schlumpf Mountain Drive). According to the Manual-Schlumpf-Mountain-Drive.pdf Please note, that Rohloff only ...

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, ...

What's the deal with Rohloff and Gates Carbon Drive?

Rampant Guess: Given how much Rohloff likely values their reputation (the hubs are hailed for their longevity under poor conditions) they are likely being extra cautious as the set up might produce ...

Gates Belt Drive+Rohloff - What rear sprocket do I need to help me get up hills and mountains better?

With the existing 50T chainring and 19T cog your gearing ranges from 19.8 gear inches to 104.2 gear inches (assuming 622 wheels) So you're essentially loosing about a gear at the top end and gaining a ...

Is there a more sophisticated tool than Rohloff HG-Check

I bought one too - on the same idea of having a better way to check for chain/cassette wear. Its pretty useless to be honest. The best tool for knowing how much mileage is on a chain/cassette is a ...

Why are IGH minimum gears expressed as ratios not contigent on wheel size?

What propels you forward is force not torque. A small wheel requires little torque to generate a given force, whereas a large wheel requires more torque to generate a given force. Thus, on a small ...

The bicycle is being propelled from the drivetrain, not from the rim. Assume the worst case scenario: the wheel is frozen in place and the rider is pushing on the pedals. The chain tension force here ...

Using Rohloff with a thicker chain

You could use a wider chain, even with narrower sprockets. As long as it's got a matching pitch (1/2") and it doesn't rub anywhere on the bike when fitted.

I've broken a spoke on a well-built wheel simply from hitting a bump in the road a little too hard. And on a generic wheel, I've seen that when one spoke breaks, the spokes at 90° intervals from it ...

Rohloff gear can only shift between 3 and 4, even when gear disconnected from hub

Check the cables. Rohloff classifies the gear shifter cables as a consumable. They may wear out and need replacement over the years. Check the gear shifter cables carefully for any damage; they ...

The answer turns out to be no. Need to rotate the shifter all the way to the stops, beyond 1st and 14th gears: "make sure the cable is taut before cutting" around 1:12.
