Bought to remove a worn bike chain in order to refit a replacement. Very handy and relatively easy to use, once I had viewed an instructional YouTube video first! Initially I was confused as to how the ‘sliding cradle’ part works! Well made, portable, robust tool. Essential tool to carry and very effective in either breaking an existing chain or removing links to shorten a replacement chain!

I replace 5-10 chains a week and had a tool that ‘did the job’.But eventually it wore out the threads, so I replaced it with a much more ‘expensive’ one……Have to say, I have been mightily unimpressed by the replacement, so I bought the Park Tool CT 3.3 to replace it.WOW!What A difference!I appreciate that for the average cyclist this is a very expensive tool, but if like mine, it’s going to be used ‘regularly’, it is well worth the investment.The CT3.3 is 3 times the price of my previous tool, but as you can see from the pics, it’s also far more robust and frankly, far better designed.Very happy with my purchase.

Fantastic quality and did the job my (cheaper) chain tool failed to do. Should have just bought this in the first place and not tried to get away with cheaper items.

Purchased after previous chain tool broke.It’s more expensive, however you get what you pay for. Excellent tool well made, work every time.
