- While I can’t speak on behalf of maintenance, the system itself is one that doesn’t need much according to Truvativ. Essentially it will be a lube your chain and you’re ready to go with some routine maintenance to make sure the HammerSchmidt continues to flourish.
- To shift into an easier gear, you need to pull cable (push the big thumb lever). This is the reverse of what is normally done but it is less of an issue as there is only two ways to shift, and if you do make a mistake it is a quick shift to recover since HammerSchmidt shifts so quickly and requires no pedaling.
- I would’ve personally liked to see a two piece style crankset and external bottom bracket setup personally but the test setup proved to be issue free.
- There is currently only one mounting setup to install the HammerSchmidt shift cable. Top pull derailleur frames and even some bottom pull frames will have to rework how to get the shift cable to the HammerSchmidt. In addition, the position of the HammerSchmidt cable entry while I didn’t experience any problems with could potentially be less than ideal in the event of an ill placed obstacle.
- While in the lower gear (22t/24t) the bike pedals like a normal crankset without any feel of drag. Once the shifter is pressed and overdrive is engaged I did feel some drag in the system that didn’t feel quite as effortless as a non HammerSchmidt setup. The system we rode was a pre-production version and brand new so some of this smoothness could be alleviated once the system breaks in.
- The overall system weight of the HammerSchmidt will come down over time but currently it is a bit portly when compared to lighter setups.
- The HammerSchmidt is built around 22t/24t setup and as such means that your suspension will react similarly to riding in the granny ring. If more bikes are designed around the granny ring this will be a mute point but currently there are some designs out there that don’t pedal ideally in the granny ring and the HammerSchmidt will suffer in those designs.
