In this article I will review the BSCTools Chain Breaker Tool, a high quality workshop-grade Chain Tool that is cleverly build with the BSCTools Screwdriver SDH-1 handle as the foundation. The BSCTools Chain Breaker Tool works with all Shimano, SRAM and Campagnolo chains (you can get an extra breaker pin for that).
TABLE OF CONTENTS
Key design features BSCTools Chain Breaker Tool
On the product page for the BSCTools Chain Breaker Tool you can read the following description:
For all speeds of chain plus Campagnolo Peening.
Works with SRAM flat top chains – have the flat at the top.
Detachable handle is also a 1/4”screwdriver.
Now can be used as a pivot press with the included M8x1 stainless steel flange nut.Steel body, stainless steel shaft, handles and screwdriver connector, aluminium handle. Hardened steel pin (spare pin included).
2mm allen key included for detaching the screwdriver handle, when not in use the allen key fits inside the handle.
Despite the Shimano Quick Link (or alternative from SRAM) and a the BBB LinkFix BTL-77 pliers you cannot be a home mechanic without a proper chain breaker in your toolbox. At minimum you need a chain tool to adjust a Shimano HG chain to the correct length for the chainring cassette combination of your choice.
Modular design with BSCTools Screwdriver SDH-1
The orange handle of the BSCTools Chain Breaker Tool is actually the BSCTools Screwdriver SDH-1. You can call it modular design or two-tools-in-one, but this clever design and one of the coolest things I have seen in any Chain Breaker Tool design.
The BSCTools Screwdriver SDH-1 is a proven robust and very versatile tool. With the 2 mm allen key bolt, there is a solid mechanism in place to lock the handle and chain tool.
Another advantage would be that you don’t need to take an extra screwdriver/bitholder with you on a short cycling holiday. So super clever design work from Dave.
Pivot Press – Hidden tool in the BSCtools Chain breaker
The first and foremost important option of this tool is being a chain breaker for SRAM, Shimano and Campagnolo chains.
Second tool option included is the BSCTools Screwdriver SDH-1, which is the handle of the Chain Tool allows you to work on your bike when you have a box with quality bits like the PB Swiss Tools box of precision bits.
A third and hidden tool option is a pivot press for rear suspension pivots (given the length of the threaded handle). So if you have a fully suspension cross country racing machine you are covered with this 3-in-1 Chain Tool from BSCTools. Simply remove the threaded handle, remove the pin, use some drifts with 8 mm holes in them and the flange nut.
This is by my knowledge the only chain tool that can be used as a press for rear suspension pivots. So a cool and unique feature from this BSCTools quality product.
Concluding thoughts and wrap-up
The price point of the BSCTools Chain Tool is £ 64,00 or € 72,82 (of which £ 16,66 is for the Screwdriver SDH-1 handle). It is not cheap, but compared to the Abbey Bike Tools Decade Tool for € 222,00 it is a bargain. 🙂
I’m amazed by the quality and well thought-out engineering of the BSCTools products that I’ve reviewed so far. It are workshop grade tools, sometimes with big improvements over respectable cycling tool brands. So if you are looking for a bomb-proof chain breaker tool, than you can’t go wrong with the BSCTools Chain Tool. Reviewed by Dave Rome and benchmarked against other brands.

About BSCTools
BSCTools originally started the business servicing bikes and slowly made more of our own tools as the need arose for use in the workshop. We started selling these hand made tools on eBay and before long we struggled to keep up with demand, so we started to get the tools manufactured.
Gradually we sold more and more tools, expanded our range during lockdown and are now purely focused on producing quality bicycle tools. BSCTools likes to make high quality, precision tools that make the job of the mechanic that much easier – the right tool for the job!
BSCTools is always developing new tools – please get in touch if you have any tool ideas or suggested improvements to our current tools!
