15mm wrench

Does anyone carry a 15mm wrench in their repair kit in case a pedal comes lose?

My pedals don't "come loose."

I carry a 15mm wrench when on my single speed but it's for wheel removal.

I do have a portable chain breaker tool that is also an adjustable wrench that might open to 15mm that I carry, but not for the pedals.

The last pedal I had "come loose" the whole pedal slid right off the spindle, never had a pedal actually fall out of a crank. I keep a 15 in the portable tool box due to the number of cheap or track bikes I give quick tunes to. my standard 15 also doesn't fit a lot of pedals, there's a reason for the thickness of the average pedal wrench. But the one I do keep in the repair box is also one of the best ratcheting combination wrenches you can buy, one of the few sizes I think is worth investing good money on since its also the most used sizes for hard work.

If you are losing a pedal you have not tightened them properly more than likely. I haven't had a pedal come loose ever on any bike. Once had a crank arm that started going loose but I went home reinstalled it and used a better torque wrench and no issues since (and I have checked it). Most of the quality pedals have a 6 or 8mm anyway so if something does happen I have something on my multi tool.

I carry a 6mm hex wrench for other reasons but that would work on my pedals. Can’t recall that happening though.

Carrying a stubby 15mm wrench would be a friendly gesture, in case someone with bolt on wheels needs to change a flat or make some other repair. I should probably get one, but my remaining, functional seat bag is small and about full at this point. So, that would probably need replacement as well.

This would be a better choice if you regularly need to install/remove pedals during your ride. Sometimes regular wrenches are too wide and the extra leverage of the longer handle is useful.

I carry a stubby 15mm wrench on one of my bikes, but not for the pedals (never had one come loose in the last 50 years!). It is for removing axle nuts so that I can fix a flat.

The threads on pedals are designed so that they do not come loose while riding.

Torque them down properly and don't worry about it.

Yes all the time but for wheels. I even have a number of 14mm/15mm double open end wrench for the bikes with 14mm up front and 15mm in the rear. 4, 5, &6mm allen wrenches, and a piece of 8mm hex for some crank bolts. The 8mm piece fits in an 8mm box end.

I've had pedals fall off from a combination of the bearings failing and not so tight installation. Lesson - check bearings. I don't carry pedal wrenches unless I"m doing a very long unsupported tour (and probably not in this lifetime).

The fact that the pedal unscrewed is rather reassuring for this fix gear rider. (It happened onmy road bike so it was a complete non-issue other than getting myself home.) If a fix gear pedal's bearings froze and the rider's foot was securely clipped in and the pedal didn't unscrew, that could be rather bad. (Let's spin this rider clockwise by his foot!)

In 30+ years of riding, I've never had a pedal come loose. Pedals self-tighten and I just snug them up securely with anti-seize compound when installing. I have learned the hard way that over-tightened pedals can seize onto crank arms easily.

If your pedals are coming loose, somethings wrong. I don't even tighten mine to specified torques. Loose pedals have never been an issue on any of my bikes.

As for what I carry in my saddle bag.... a couple hex keys, small screwdriver with changeable points, a tube and a CO2 inflator. Oh... a house key and maybe some stuff I've long forgotten. Other than using the house key, everything else has been unused and just extra weight.

I carry a Park RW-1; fits 15mm pedals and fixed-gear axle nuts, and 32mm threaded headsets, and is small enough to go in an under-saddle bag or can be mounted under a frame-mounted bottle cage.

Only reason pedals would come loose is if you setup a left side chain set with the chainring, fixed cog and everything on the left side. It can be done but takes special left hand parts.

And if you're actually losing it, then you might want to tighten down your prosthetic foot as well. I'm here to help.

The 15mm wrench is for nutted axle wheel changes (i.e., fixed gear or single speed).

Picked up a 15mm stubby to throw in the saddle bag. Seems like an unlikely event, but I'm prepared at least.

Thanks fo the replies.

Some pedals have only hex or only flats for a pedal wrench - I won't use those. I want to install with a pedal wrench and have the hex option in case of an issue out on the road, which has never, ever happened.
