Chain Tensioner
NC-17 DH/4 Cross chain tensioner: As long as frame manufacturers fail to integrate chain guides with their DH frames, we will continue to develop NC-17 chain tensioners. There are many systems out there now, but only one winner.
The NC-17 Tensioner uses two guides to keep the chain running true- using sealed cartridge bearings and specially formulated rubber to keep the rolling resistance and noise to a minimum. The body of the Tensioner is made from 7075- T6 aluminium to keep the weight down but is supplemented at high stress areas with high grade steel.
The Tensioner is attached by fitting behind the BB-Shell and then securing against rotation with small grub screws (apart from the ISCG version).
The Tensioner is available for standard, compact drive, 4 arm cranks and in ISCG.
The Stinger 1 arm Tensioner represents a minimalist alternative using the same
7075 T6 alloy, sealed cartridge bearings and special compund rubber to keep things light and running smoothly.
If you want a seriously cool look then you can go for a Lexan disk rather than the standard Aluminium disk. For cost reasons we only produce the Lexan disk in one size (4 bolt, 104mm). The Stinger 1 arm Tensioner represents a reasonable alternative. Our Tensioner is standardized
