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

Honey, will you pass the lube?

Call me old fashioned or maybe even call me wrong but I've been using GT85 to lube my bike chains since the early 90's, somebody back then must have told me it was a good idea...Anyway it seems things have moved on in the lube world quite a lot since then so its time to get with the times.
One of my riding buddies (Chris) talks highly of Rock 'n' Roll lubes, specifically Extreme Chain Lube which is some strange, gloopy blue stuff so I thought I'd give it a go so the Rohloff SLT-99 has had a nice bath in the stuff and tomorrow i'm off to some really shitty (mudwise...) forest down in Suffolk that has some nasty gritty sandy soil that really gets into the chain and mechs so this will be a good test!Man sized, Extreme lubrication So, once the chain had a birthday I gave the whole bike a check over and paid some attention to something that many people leave untouched....the saddle clamp.
If you think about it this is an important piece of kit, you have your ass sat on it for long periods of time but it gets blasted with crap off the trail and probably doesn't get cleaned real well. So I stripped mine down, coated all the threads and brass inserts with Anti-Seize Compound, put a big bunch more on the rail clamps and put it all back together again....nice smooth bolts and no more creaking Ti rails Cleaned and greased Syncros clamp As the Flite Ti was taken off the bike to clean up the saddle clamp I figured I'd swap in the SDG Kevlar Ti Comp that I got from the USA, I've been curious about these (as mentioned in a previous post on here). To be honest the profile doesn't look much different from a Flite but its gonna stay on for two big forest rides tomorrow so I'll report back later...Nice rails  So the bike is more or less ready for tomorrow, just gotta get some air in the tyres.....watch this space for a ride report over the next few days
