何か質問はありますか？ チャットでお問い合わせください

お客様の質問と回答

  • 質問: Is this screw compatible with all Shimano derailleurs?

    回答: It is compatible with most Shimano mountain bike derailleurs.
  • 質問: Is it easy to install?

    回答: Yes, it replaces the stock B-limit screw on Shimano MTB derailleurs.
  • 質問: How durable is the stainless steel screw?

    回答: It is made of high-quality stainless steel, ensuring durability and reliable performance.
  • 質問: Is this product compatible with Shimano Derailleurs (specifically a 105 10sp)?

    回答: It fit on a circa 2001 LX.
  • 質問: Is this considered a Dropout screw for adjusting tire between stays?

    回答: No it is for adjusting the rear derailleur jockey wheel further from the cog.
  • 質問: Will this work on Suntour Honor derailleur?

    回答: I believe all the B-screws are the same.
  • 質問: Shimano Ultegra 6800 compatible?

    回答: Worked in my Shimano setup.
  • 質問: Will this work on a pure fix frame?

    回答: 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.
  • 質問: What width or size is this M4? Thread type and length.

    回答: Take the old one to the hardware store and match the threads and size. They are metric. 25mm is long enough to adjust body angle of derailleur for clearance between biggest cassette cog and upper jockey wheel when in lowest gear.

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.
