The old marins were licensed from doug bradbury to use his rear shock system off his own manitou fs frames.
Marin actually had one of the first bikes with front suspension way before anyone else....they used a browning fork that had suspension inside the steerer but it was never released.The flex stems were awesome to ride until they started squeaking...they had so little travel that they couldn't dive...they just removed buzz.
It was the allsop frankenstem that the ritchey team used that could pitch you over the bars as it had way more travel.
That was the one - that Ritchey frame was amazing...
-
It was built back when MTB's didn't have suspension options beyond flex stems....people were experimenting with ways to soften the ride, save weight. For me personally, that was the most exciting time in MTB history....the ideas and innovation going on was far more interesting than the cad designed suspension frames that appear today.
Re. the back brake...there weren't exactly many brake options back then apart from cantis or u-brakes.Second this - some of the designs were nuts back then. I used to own a ProFlex which I guess was about the time that rear suspension frames started to standardise a bit more. I was flicking through an old MBUK magazine which had coverage of a trade show from the early 90's... there were some really different ideas knocking around.
The old Marins looked like they just used to mount Manitou forks on the back of the bike as their effective seatstay I seem to remember! Others had odd shaped elastomers or huge rubber donuts at various places on the frame...
And that Girvin stem was a shocker wasn't it? I never actually rode one, but I seem to remember hearing that if you went through a transition from a steep downhill to flat, it would compress and try to throw you over the bars :)

lo pro anyone?
dammit I wish I hadn't seen that... I've wanted an Aende for ages, and that looks cheap, just got no money at the minute!

So it's ok to take the piss out of someone's bike, as long as they aren't a member?
It's obviously perfectly acceptable to take the piss out of non members bikes :)
Personally I wouldn't post someones bike who had tried to show it off in the projects page (or anywhere else), seems like good manners if nothing else.

Found something like I'm aiming for with the Klein:
http://www.oldklein.com/kleinit/AttitudeShiny.htm
I have carbon forks and seatpost, should I sprinkle it with anodised bits headset, seatpost clamp etc?
Always wanted a Klein, those Attitudes were serious bikes. Can't tell the vintage of yours (it's not one of the old 1 1/4" headsets is it?!) but looks great. Surely for period looks on a polished frame, it should be covered with as much purple anodising as you can get your hands on ;)
If you're going to refinish it, how about this?

I 'be-leaf' I will take the chainset/pedals if you're willing to post?
(seriously, I will take the chainset, this isn't just an opportunity to pun shamelessly...)

aah - pretty cool

i know it's crazy isn't it? apparently all replica aeroplanes of that era are made at 90%. it's something to do with insurance i believe. i really don't know too much about it. stranger still, once it's built it will be the only functioning spitfire in england (apparently)! there are several in museums but no working replicas. that to me is unbelievable.
That's interesting... what about the one that the RAF have (with the huricane and Lanc) that they roll out whenever one of our ruling classes has a significant birthday?

from my experience with downhill bikes and the forces put through discs the strength is no way a issue, i was running 200mm rotors at one point and had no problems at all and other times running a few bolts less and again still had no problems. if i had a disc mount cog set up i would bet my life that it would never break.
I'd agree with this - and add that I'd imagine the chain would break long before the sproket bolts go. The end result would obviously be the same, no brake or drive and not great, but just saying that those bolt on cogs look bomber.

Yup you're right.
Welded differently, but definately not fillet brazed. :)"And now a word about Cannondale's hallmark smooth weld bead. It's a common misconception that said weld bead requires sanding to achieve its smooth finish. In fact, the weld bead is smooth, right out of the weld booth. The smooth finish is created by a two-pass, puddle welding technique that Cannondale employs. Cannondale points out that their welding technique produces better penetration than welds that exhibit the typical "stack of dimes" appearance. Better penetration results in a stronger joint. Furthermore, the high and low spots on stack of dimes weld beads may act as stress risers—a potential compromise of weld durability."
aah yes, the good old 'two pass puddle' technique :)
-
Welded and filed smooth.
I seem to recall that 'Dale didn't used to file their welds - they welded them differently, something to do with heating the weld up more (or after it was completed) so that the material all sort of flowed into each other... I'm sure that description isn't quite right, but remember it was quite interesting at the time.

Looking for some cheapish brakes to put on my new project.
Pretty relaxed about makes / model, if anyone has anything they want to sell, then do give a shout.
Cheers

do you guys actually think that yellow low-pro is an orlowski???
:S
No idea, thought it was not pretty though; and kids bike or not, its not :D
-
new orlowski model
I was going to ask why that headtube was so big... but then I started looking at all the other bits... not pretty...
-
Not particularly helpful but also keep an eye out for an old Azonic dual slalom frame on ebay - horizontal dropouts and very cheap - I picked one up for £30 - looks great after a trip to the powder coaters...

Hi Timmy,
Not sure if you got my message from earlier, just joined the forum to try to post to you! I've just noticed that I might not be able to PM peple yet, so you may not have got it...
I'll take the frame and forks at the price you state above if they're still available.
Cheers,
C

I think those shimano ^^ hubs from Velosolo are a great idea... It's possible to polish up the silver one a lot (saw this on a website somewhere, possibly velosolo) using the old oven cleaner / autosol method...
