Torno SRAM Flattop Chainring by 3T - Optimum power transfer


The Torno chainring for Torno cranks by 3T is ideal for gravel racers with SRAM Flattop. Since the screw threads have been recessed, the 3T Spider is inserted into the chainring, so to speak, and can thus act directly on it. This means that the force is not only transmitted via screws, but also through the shape. The special 1-speed chainring was equipped with a Drop Stop tooth profile for the best performance. It is compatible with all 11-speed chains, the 12-speed SRAM Eagle chains, the 12-speed SRAM Flattop chains of the SRAM Force AXS and the RED AXS groupsets.

Technology:

Drop-Stop:
Wolf Tooth has invested countless hours in the design, prototyping and testing of their Wide-Narrow chainrings and has developed a highly innovative tooth profile. Test riders around the world have confirmed that this design brings unparalleled performance.
The right side of the chainring tooth has a different shape than the left side. The right side transmits the power to the chain and the left side opens a free space for cleaning off mud and dirt. Since the two sides have completely different functions, it makes sense to design them true to the motto: extra reinforcement where you need it, less material where you don't.
The right side of the Drop-Stop tooth is as wide as possible to distribute the load over a larger area, which also minimises wear. The left side of the Drop-Stop tooth helps to guide the chain, but it does not transmit any load. Therefore the left side is narrower than the chain roller. Wear is not an issue on this side, so Wolf Tooth was able to save material and create a better mud clearance channel. More free space means less friction and less change of the chain being dropped due to mud.
