      Comments about Surly MR Whirly Singlespeed Crankset:

      I shopped around and decisively settled on my Surly Mr. Whirly SS Crankset for my 2012 Trek Sawyer (a fully rigid retro 29r). Although I'm a very mediocre (self trained and still learning) bike mechanic I had minimal difficulty installing Mr. Whirly and replacing the rear 10x cassette with a Surly SS Cog and spacers (Thanks to Surly's Simple Man Instructions). I must have done alright because I've been enjoying my ride ever since (well beyond 1000 miles), and have experienced no problems with Surly's outstanding components. If I had to downgrade this product in any area it would have to be the expense. But, when you consider the R&D, materials, manufacturing, workmanship, labor, distribution, shipping, handling, etc., I just can't go there (and no, it's not because money comes easy - it doesn't). It's just a great product and to me the value shines through all the muck involved in making and keeping a buck. As an added bonus (and most important bonus) the value also shines through all the trail dust, muck, etc., as evidenced by the shed eating grin on my face every time I turn the cranks. And, NO I don't work for Surly - they're thousands of my away, someplace back East.

        The Mr. Whirly crankset is still going strong after 4 years of abuse. Coupled with a Rohloff speedhub on a Big Dummy, this thing should last many more years. I do wish it came in a 170mm version for my short legs but I make do with the 175mm.

          Nicely designed product adaptable to many different set-ups. Converted a vintage MTB frame to single speed. Love the different spider options to put any BCD ring on. Highly recommended and would purchase again.
