Park chainring tool

Darius_Jedburgh

Looking for the lost chord.
You "can" manage without one. Most of the time you can simply jiggle a screwdriver and hold the back of the bolt while you turn an Allen key at the front.
But....there is always one that is stuck fast. Try as you might it will not come free and it's usually the last one.
For the price these are well worth having in your tool box.

There is the added benefit that if you buy one of these your bolts will always come free without you needing to use it.

Or if you don't have a screwdriver with a wide head, a butter knife or paint scraper.

I bought one years ago thinking it would get well used. It's still in my tool box without ever seeing the light of day. It's a tool that never needed inventing as there are a multitude of other bits and pieces that do the job just as well. Usually you stick the hex key in the chainring bolt, it comes undone, you remove it, change the chain ring, replace it. Even the pressure of your finger on the back of the bolt is enough to stop the nut swivelling round. I'd be VERY excited if Park were selling a useful tool for under a fiver though 🥳

Mines had a lot of use over the years.

According to some, you are clearly doing this wrong then!

Classic internet thread:
Q."Please recommend good tyre levers!"
A."You shouldn't need them."
A."you have crap technique."
A."Are you man or mouse??"
A."I don't understand why anyone needs tyre levers ... "
That sounds about right. :laugh: I've had mine about 20-25 years, they're a lot easier than trying to hold it with a finger, it doesn't always always work, looking for a flat bladed screwdriver that fits, I can never find one when I want one and it wastes a lot of time looking for it, other house hold items that might fit, same rules that apply to screwdriver apply to assorted household item.

I don't understand why people use screwdrivers when suitable tools can easily be improvised from common items at zero cost. Do they have money to burn??

You fool, you have been duped into buying the dream pushed by the slick marketing of Big Tyre Lever. Stop reading Tyre Lever Weekly and stop believing the hype.

Sorry we've gone way off topic.

I've never used one (hence my ignorance and my enquiry here!); from the pictures, the advantage over the "perfect plain screwdriver" appears to be that you're holding it like another allen wrench (while turning an allen wrench on the other side) i.e. your hands can be quite close together, and both get good leverage.
So there's a plus.
The likely cons would seem to be how well it fits, will it slip, etc.
And of course unknown unknowns. (such as looking like a total newb on cyclechat - what price can we put on THAT??)
