Wolf Tooth Components Drop-Stop B chainring
If you’re planning on converting your double chainset to a single setup, or simply replacing your worn-out 1x chainring, the Wolf Tooth Components Drop-Stop B is a great option. It has worked flawlessly for thousands of miles, with no dropped chain, and it's quiet too. The deep valley between the teeth also securely accommodates the large rollers of SRAM's flattop chain.
This chainring uses Wolf Tooth’s patented Drop-Stop technology to prevent chain derailment and increase longevity.
Wolf Tooth says, ‘The wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.’
The introduction of what it calls Drop-Stop B is a slight change to the chainring tooth profile that means it can be run with SRAM AXS 12-speed groupsets, which use the proprietary flattop chain that matches the new profile chainrings. It's also compatible with almost every other 9, 10, 11 or 12-speed chain. The chainring is available in various fitments for different chainsets.
We used the chainring with a SRAM AXS Force Wide groupset in a 1x road configuration, including a 12-speed AXS chain, and the performance was perfect. It has been tested over thousands of miles, in all conditions and has given flawless chain retention, even on bumpier roads and lanes in the smallest 10-tooth sprocket.
The amount of wear showing is also very small with just a little anodising coming off on the extremes, so we have confidence it will last for a very long time.
