The Lifeline Performance 2 in 1 crank remover is a workshop staple for pulling square taper and splined cranks off their axles. Or it would be, if our sample hadn't broken.
It bears more than a passing resemblance to similar tools from household names. It's an integrated design, complete with floating tip for precise alignment with ISIS types, which run to slighter closer tolerances.
The standard of machining is pleasing and more than good enough for occasional use, though it benefitted from a quick drop of wet lube to achieve the flushest possible fit.
Unlike more expensive crank removers, there's no 14mm socket or 8mm Allen key here to remove the crank bolt, so you'll need a standalone tool for that.
To remove a square taper crank you then unscrew the tool head and its tip before engaging with the crank arm. Turn carefully until you're satisfied everything's correctly aligned, and back up and start again if in any doubt.
I was able to get the extractor to work with some cranks that had partially striped threads, indicating that the fit is very good. There are spanner flats on the head so you can snug the tool into the threads.
Two complete revolutions of the 190mm handle were enough to free even the most weathered examples, although a quick shot of maintenance spray certainly helped. For ISIS systems, only the floating pin must be engaged.
I was beginning to bond with our sample quite nicely when, on the fifth run, its floating pin sheared without warning under surprisingly little force.
Chances are this was a fluke and easily addressed under warrantee. Nonetheless, I'd be inclined to spend a little extra and invest in a premium model.
Too fragile, if our test sample is indicative, but worked well till it failed.
