Sunn Urge Comp 99

tufty

Retro Guru
So, I got me an addiction to french* steel.

I came across an ad for some bits on the french equivalent of fleabay, with the tantalising comment "I've got a lad of other Sunn stuff to get rid of, for example an Urge Comp 99 frame in L". A few emails back and forth, a quick trip to Lyon and an exchange of 50 euros, and I had me a slightly tatty Urge. Well, a tatty frame with decent enough stickers, a blocked bottom bracket, and half a headset, at least. Plus a few extras - a fairly heavy seatpost, some pedals, a crankset (not the one in the photo below), and so on.

I flogged my existing Xircuit frame for the same price I paid for the Urge. In under 24 hours. Perhaps I misjudged its value, but it went to a guy I know, and it will be loved.



It was fairly obvious it was going to have to be resprayed. No major frame damage or rust, but the paintwork had definitely seen better days. So full strip down, and let's get busy.

The bottom bracket proved to be a sticking point, quite literally. No way was it coming out (and yes, I do know which way to turn, forwards to get it off, and then "back on"). Big socket set with a 1.5m cheater bar, big vice, rattle gun, and even after massively brutalising the poor thing (ripping out the axle and bearings and smashing the cartridge in an effort to reduce the stickage) it wouldn't budge. The splines eventually gave way on both cups, and I had to resort to a caustic soda bath to get it out. Not pretty, but no frame damage incurred.



Stripping the paint off took 2 days.




Shot it with some white primer...



… some rather disappointing "pearl white" and then a clearcoat



A new FD-M750 goes on, along with a Ritchey logic headset and a Tange bottom bracket. The latter was a steal, less than the going price for a BP-UN55, from the highly recommended http://hubjub.co.uk, and weighs a mere 230g. New cable kits from jagwire, some mounting, and it looks like this. I also repainted my old FC-M510 crank arms, because they were tatty. I'll probably end up re-anodising them at some point, but white enamel works for the moment.



Waiting for a Woodman seatpost in black and clamp in red, find a way of resticking the un-re-do-able stickers, and it's done...

*actually very few of the Sunn bikes were actually made in France, only the real top of the range stuff was actually welded in St Gaudens, the rest was welded, like everybody else's stuff, in Taiwan. But I digress.

Good work, my friend! 8)

Nice tip about the bracket, are they a lot lighter than Shimano ones?
What are the forks? Can make them out on my little phone screen! :oops:
Also, what did you use to strip the paint?

Hey Mike.

Forks are XC700s, not as light as the Obsys carbons but a nicer ride. The only downside apart from unbtainium seals is the adjuster at the bottom of the fork leg meaning you have to stop to go from lockout to suspension, but you stop at the top of a climb anyway, right?

The Tange 7922 BB is 10g heavier than the Shimano XTR BB-UN91, but that's discontinued and you end up paying the XTR name as well as NOS R@RE!!!!. About 20g lighter than the BB-UN71 (XT, also discontinued), and 70g lighter than the BB-UN55, which is the highest spec square taper BB Shimano sell these days. Going lighter means paying C@RBON TITANIUM R@RE!!!!

For stripping, I went with a mixture of nasty aerosol crap from work and some "Strips anything fast" stripper, plus a wire brush and a stanley knife blade for the "picky" bits.
 
So, bastarding clearcoat never hardened as it should have, So, back to bare metal again, and then a monocoat industrial paintjob. In a "totally" catalogue-spec colour, RAL 6018 "Yellow Green".
