Hi guys,
here is the first bike in Indonesia with the brand new Hammerschmidt dirve train installed.
The conversion from a traditional crank to Hammerschmidt is pretty straight forward. You need a couple of special tools to prepare the BB (you need to face the BB and the ISCG mount) before mounting the crank, but besides that it's pretty simple.
The Hammerschmidt can only be installed on frames with ISCG mount!
The installation took around 1 hour to setup the BB and to make sure the ISCG mount is even, once the ISCG and the BB is done it's easy.
The Banshee Scythe setup is following:
-Hammerschmidt FR with 36/22T ratio (you can also choose 38/24T ratio)
-SRAM X.9 trigger rear with the matching X.9 Hammerschmidt trigger
-SRAM X.9 Super Short Cage with 11/34T cassette
-SRAM PC-991 chain
Saturday morning the initial testing was done on flat ground before it's being put through the paces on Sunday/Monday at our house track in Bedugul.
The shifts (even under load) are instant, you can shift while cruising and even paddling backwards or standing.
On a normal 24/36T crank you have around 1/4 to 1/2 rotation of the crank delay when shifting - here the shifting is with a blink of an eye, no rattling - very precise.
Improved ground clearance (you are basically running a 22T chainring).
No chain slack - with a super short cage no chain noise - shorter chain less weight - less slack.
After the conversation the bike gained a mere 350 grams of weight, than before (single chainring 36T/Gamut chainguide set-up).
Well let's see what the real world testing will bring in the next couple of days.
