Lezyne Chain Drive chain breaker – Revised Review


  • spoke nipple tool
  • smooth action
  • comes with a spare pin.
  • good ergonomics fits nicely and securely in my hands.


  • Flawed handle design, the rubber ends pop off, you need them so the rod does not slide off, and be shoot off somewhere like out your window. to fix this, by replacing the the ends with Gorilla Tape or similar

Like so:

Lezyne SV10 Multi Tool Long-term review

I had this multi-tool for several years.

A few years ago I managed to bend the Allen key, I don’t remember how, maybe I dropped it.
I actually had to bend it back as it was so bent it was not possible to tuck it in.I had to buy a multi-tool, and this was the easiest solution, but it does have all the tools I need, for example, the Allen key used for reach adjustment on Shimano brakes.

But the size makes this multi-tool fit into tight places well, for example adjusting pads on mechanical brakes. It served me well the few times I had to use it for my own bikes, but I also used it many times on other peoples bikes, So it got a lot of use combined, but I need more tools than this tool has.

I have dropped it many times on hard ground like rock surface and asphalt.


  • chain tool spins smoothly.
  • Robust and smooth, you can easily rotate the tools out, and they don’t wobble, htere is no play, if you notice play, the bolt just needs to be tightened.


  • not enough leverage for very tight bolts.
  • The stitching for on the sleeve wore out fast, so it was too slack, but that’s easy to fix.
