DMR STS Chain Tensioner

No, the DMR STS is specifically engineered for frames with vertical dropouts. If you have horizontal dropouts, you can usually tension your chain by sliding the wheel back in the dropouts, making a tensioner unnecessary.

While it is built with the durability required for dirt jumping and street park, it functions perfectly well for general single-speed mountain biking. The stainless steel construction is robust enough to handle trail debris and varied riding conditions.

The pulley features sealed bearings, which are designed to keep dirt and moisture out, minimizing the need for regular maintenance. You should only need to clean and lightly lubricate it occasionally to keep it running smoothly.

The unit features an adjustable pitch, which allows you to fine-tune the alignment of the pulley with your chainring and sprocket. This adjustability is key to ensuring your chain runs straight and doesn't drop under load.

Yes, the STS is compatible with standard single-speed chains, including 1/8" and 3/32" widths. It is designed to accommodate the typical chain lines found on most single-speed conversions.
