Less efficient than a long handled pedal spanner, the SS-15’s rigidity compensated, and even stubborn examples released without herculean effort, or resorting to penetrant sprays. Same story with the track nuts-I’ve tackled these both with the designated socket and the open “pedal” end to similar effect, the latter being used where the socket would foul carrier frames. Again, there’s sufficient torque to snug everything down without going OTT. It's also very accurately machined, so slippage, or rounding won’t be attributable to the tool.

 

I had my fixed gear winter/trainer’s chain jam while tackling a greasy S bend. I was able to remain composed, coast to a halt and slacken the rear track nuts, releasing the chain cleanly and efficiently, albeit needing to release the chain tugs with a 3mm Allen key, first. 

 

Back on the road within seven minutes, track nuts snugged dependably tight. The rest of the 20-mile loop done at a decent lick with a quick onceover having reached home.  The bottle opener is also very effective, if you’re into a mid-fettle tipple. I’m not too taken with steel tyre levers. 

 

Describing the SS-15’s as an afterthought would be a little harsh, but very much a get you out of a jam, rather than first resort-I’d definitely pack a couple of composite levers along for the ride. Leverage isn’t the issue here, there’s oodles of that, rather caution’s needed with alloy rims and indeed, to avoid pinching tubes. While I can see the reasoning behind it, I’d rather something like an 8, or 10mm spanner for tackling things like barrel adjuster, or mudguard hardware.
