this is a serious tool. I own several bikes, with Shimano and Campagnolo drivetrains. This tool works great on both. It's solidly built. It holds the chain rock steady as you push out the old and push in the new. If you like to change your own chains, or remove them for cleaning as I do, it's totally worth the investment. Highly recommended.
The tool seems well designed, but be sure to order extra pins with your order. The pin on my tool broke with the first usage. It could have been lack of finnese on my part, but nonetheless I'll need to order replacements before my next usage.
Thanks for your review! I asked our customer service department to get in touch with you about the broken pin -- we usually find these tools to be quite reliable and trustworthy, so we'd like to help you out. If you have any questions, you can always get in touch with us at [email protected]
