I think I have a Top Peak one, it has every thing I think you’d need even tyre levers. It’s currently in my saddle bag and hasn’t seen light of day for sometime fortunately.
But I’ve probably just jinxed that.😳
I’ve got the same, even has a chain splitting tool, like yours never been used!
That’s a hard question. Most tools fit in a pocket but some are more comfortable carried there than others.
I seem to have accumulated a small collection over the years. In the main I have a leaning towards Lezyne. I like the quality and the choice. My son swears by his Crank Brothers tool (he’s a mountain biker). It’s sturdy, has good leverage and quality seems good. However I think it’s a little bit heavy for the number of functions.
There is a sweet spot in size. I have one Lezyne that has a lot of tools on it and I realise I rarely take it out. Too much for a local ride and if I’m on a long distance ride I’m more likely to take a collection of different tools to complement a smaller multi tool.
