The crank set I purchased is the new 2013 Shimano Zee crank set which has been designed for downhill racing and general MTB single speed applications where you need a good solid crank set in 104 BCD but do not require the added cost of a higher grade such as Shimano Saint etc. It uses the same system as the higher grade with a more basic finish. And is available for 68mm & 73mm BB shell diameters . The Shimano Zee crankset that I have recently fitted to my Kona unit is the same as the crank set pictured below
Of course I was considering changing the BB to a trad square taper and fitting either an older Shimano or Race face crank set or going nuts and ordering a nice made in the USA - White Industries or Paul Components crank set , but as I am not racing this bike I could not justify the added expense of a made in the USA crank set when the above Shimano crank set will do the job perfectly for a reasonable price.
I did receive some tech advice from the manufacturer of my old crank set , but putting a bit of loctite on the offending alloy bolt is not the best solution when that particular model crank set has been widely causing problems now for several years and is still fitted to some complete bicycles.
So what brand of crank set did I recently throw into my rubbish bin at work along with all the rusty chains, clusters and old tyres - here is a clue to the manufacturers name !
