câu hỏi:
Will this work on Suntour Honor derailleur?
trả lời: I believe all the B-screws are the same. -
câu hỏi:
Shimano Ultegra 6800 compatible?
trả lời: Worked in my Shimano setup. -
câu hỏi:
Will this work on a pure fix frame?
trả lời: This is a b limit screw designed to allow you to adjust the rear derailleur jockey wheel further away from the cogs to accommodate a larger cog. It may not be suitable for your application. -
câu hỏi:
What width or size is this M4? Thread type and length.

WolfTooth Front Derailleurs Editorial Review
If you're looking for a replacement or upgrade to your derailleur's B-screw, the Wolf Tooth Components 25mm B-Screw is a compatible option for many Shimano and SRAM derailleurs. This M4 screw is longer than the standard ones to allow for better adjustment of the cage to the low cog angle, preventing contact between the guide pulley teeth and the low-speed cog. Customers have been satisfied with their purchases of the Wolf Tooth Components 25mm B-Screw, praising its perfect fit and well-made Construction. It is worth noting that some of the reviews seem to be about a completely different product (front floor mats for a BMW), so make sure to double-check that you're purchasing the correct item.
