Riding the HammerSchmidt
SRAM setup an ideal testing ground for us in Pemberton, B.C. that highlighted just how well the HammerSchmidt would work in a very diverse area. From tight quick climbs to steep and rocky descents, the HammerSchmidt was put to the test for a few days.
Initial thoughts on the HammerSchmidt was quite positive throughout the test rides and after more and more time was spent on the system it was clear that the HammerSchmidt has clear advantages over a front derailleur system.
Installation was a breeze. It took no time to bolt up the system on the bikes SRAM selected. The system requires some specific ISCG tabs (03/05) and no you can’t use an ISCG adapter to circumvent this. The tabs require a good bit of strength to handle the torque generated so flimsy ISCG tabs might not suffice.
Another nice feature is that there is no more hassling front derailleur setup at any point whether it be in the shop, on a ride, or race. In a muddy race or tough climb situation, mud or grime won’t have you scared to shift into the lower gear. You’ll have reliable front shifting that will make you gain more confidence every time you ride it.
Overall the HammerSchmidt was durable, offered tons of clearance, and did not miss shift during the ride. There are tons of ideas for where these cranks can have a huge benefit for the rider and as more and more people install them, even more benefits will become apparent. I’ve outlined a few of the major benefits I felt with the HammerSchmidt below.
The HammerSchmidt was a piece of cake to setup with the given bikes. While it won’t work with every bike (requires ISCG (03/05) tabs and in a particular orientation), it is easier to setup than a front derailleur given comparable ideal setups. ISCG 03 is often also referred to as ISCG-OLD and sometimes just plain ISCG. ISCG 05 is also often called ISCG2005. To measure which tabs you have, you can refer to this chart as well. Regardless, the HammerSchmidt comes with both 03/05 plates as well as a template to make sure it will fit properly.
The HammerSchmidt installs in a few easy steps as illustrated below in some abbreviated steps. You can see the full set of installation steps and a video at MagicMechanics.com
