Reise & Muller Supercharger 2 GT Rohloff: Specifications & Mods

Riese & Mueller Superchager GT Rohloff Silver Matt MY 23

When purchasing and getting prepared for the arrival of my Reise & Muller Supercharger 2 GT Rohloff, I found it hard to get details on the bike’s specifications beyond the minimal information provided by Reise & Muller. Hence, this post details the specifications and, where possible, provides more specific details about my modifications and additions to the bike.

Update 17 May 2024: After waiting over three months, my Reise and Muller Supercharger 2 GT Rohloff (MY23) in Warm Silver Matt has arrived and is now home. My initial ride on it this morning from the LBS (Sparque in West Perth) to home was 20.22 km.

I hope that you find it useful. If you find this post helpful or you can add more details or suggest modifications, please leave a comment below.

Cane Creek Thudbuster with

The previous weekend, I swapped out the Cane Creek New Thudbuster ST Evo (Gen 4) for a Thompson Masterpiece 16mm setback seatpost that I had, as I was not convinced that the Thudbuster really made a difference. The Thompson lasted a week, and the Thudbuster is back on the bike. It is married to the Selle Anatomica H-Series saddle that I had on hand.

EBB Rohloff eShift Under-Bar Mount

EBB Rohloff eShift Under-Bar Mount and Mirracycle mirror

I have now fitted the EBB Rohloff eShift Under-Bar Mount. It mounts to the Magura brake lever and drops the eShift control underneath the handlebar. Initially, I thought this was not a great modification, but after two hours of riding, it felt natural. I am glad I made the change.

Mirrcycle Bicycle Mirror

I fitted a Mirrcycle Bicycle Mirror on the right-hand side. It sits below the handlebars inbound from the end of the bars. It works well in this position for me, and I am actually quite impressed with Mirrcycle. Much better than the Busch and Muller mirrors I have used in the past.

Water Bottle Cage and Pump Mount

PRO Right Side Alloy Bottle Cage Black and Lezyne Micro Floor Drive HVG pump

As a temporary install, I have fitted a PRO Right Side Alloy Bottle Cage Black within the triangle and a Lezyne Micro Drive HVG pump I had on hand. The cage and pump will be removed once I receive my frame bag from Bike Bag Dude. I will then mount a water bottle at the rear of the top tube, and the pump will likely go into the frame bag.
