Frank, it’s a Revolution…

Todays post is just for my ‘virtual Buddy’ Frank who lives in Canada and is a lover of vintage Canadian bike components, as is yours truly!!

I owe him some information and am famously slow at performing tasks like this so I figured, surprise Frank and also do a little piece on these, my most favourite of vintage MTB cranks. The Revolution Crank first showed it’s face in the 1991 Pro-Series Component Group (as far as I can remember) and it stayed around for several years with Syncros eventually making Road and Compact Drive versions. Material wise the early Revs were made from tubular Columbus Nivacrom and weighed 400g, which at the time was pretty damn light. Later on they were constructed from Tru Temper OX4 and tipped the scales at 410g.

The cranks were cold forged at 125 ton pressure which was supposed to make the metal even harder and stronger.

Syncros Cranks are either loved or hated, after all they are rather bland and boring looking when compared to something bright and garish like Kooka trash or Grafton etc, but they do the business and are very strong. They don’t look good on every bike but are a good match for any early Rocky Mountain, Brodie, Offroad Toad etc and they also look kind a neat on my EWR

For some unknown reason the value of these has gone sky high in the last year or so and its not uncommon for these to change hands on eBay for insane money, in fact a NOS set sold in Germany with the elusive Crank ‘o’ Matic crank bolts for nearly £400 just after Christmas 2009.

I am lucky to have three pairs of these, well in fact when I started typing this post I only had two pairs but I’ve just received news on closing a deal for a third pair so I now have two pairs in Standard Drive (110bcd) and one pair in Compact Drive (94bcd)

So, Frank….to get back to you, here are some pix for you, take note of the inner chainring bolt pix. The bolt is 14mm long by the way, let me know via RetroBike if you need any more info

  1. mmmm Syncros!

  2. Neill, need the inner gear spacer length! 😉

  3. I'll sort it tonight when I get home :-/
