Proflex 855 coffee cruiser build in progress!

Hello all;

I just joined up in BF. Here's the URL to my introduction with pics of my current bikes;

http://www.bikeforums.net/showthread...=1#post4753081

I felt compelled to share a little build I'm in the process of. It's an old school full suspension mountain bike as is mentioned in the title. I've dubbed it project RATROD, though it will have little to do with the Electra Ratrod cruiser.

It was already a frankenbike when I bought it, in that it was still a MB, though it had different components. Here it is as it looked when acquiring it with a kitty cat option;


Joking about the cat, of course!

I got any and all drivetrain components overhauled or replaced. I stuck on a flatbar with dept store barends, 8spd Gripshifters, Selle Royale Shark Gel saddle and that took care of the riding comfort and reliabilty issues.

I'm going for a custom look of sorts, leaning towards Brit bikes of old as opposed to a long low Harley style. The rear is a 24" with a 2.5" Hookworm, {I wanted 3" Fatty-O-Tires, but they'd rub on the rear strut stays.**, and the front, a normal 26" with 1.25" Specialized Fatboy slick.



The brake bosses on the rear swingarm are positioned for a 26" wheel, so going to a 24" meant going without rear brakes. I compensated for its absence by going to a dual front brake system consisting of a V-Brake and a Magura Gustav with a 190mm rotor. Can you say stoppie?


My next endeavour was to jerry rig a set of chrome ducktail cruiserbike fenders, {Thanks Ebay!**, to a dual suspension MB.

The rear wasn't that difficult as there was rack eyelets, {???!??!??!??!?**, to attach the support arms. A bit of trimming was required so it would fit between the swingarm by the main pivots. Then it was anchored in that area by bolting it to the brake bracket that was already in place.




The front took a little bit of brainstorming, but the method to which it was done seems to be working fine. Since a MB sus fork doesn't have any eyelets of any sort for anchoring the support arms, I chose to use basic Home Depot 1 1/2" hose clamps. I measured and then cut the support arms to length, then cut slots on the ends. The front arms attach to the front dropouts and the rears are attached to the hose clamp set screw. Since the support arms are anchored at two different points as opposed to a shared point, {like on a rigid fork with rack eyelets**, It stays pretty stable so an anchor wasn't required at the top underneath the shock crown.


The rear suspension elastomers are pretty well sacked. There's some give, but the old elastomers are collapsed and have hardened up. However, because of that the rear end is lower and contributes to its lower stance appearance. Just what one wants for a cruiserbike, right?


I'm looking to lower it a tad more, but not much otherwise the swingarm by the main pivots will hit the frame. Perhaps I'll remove one of those elastomers and see. I've got some ideas for the rear sus fix, but that'll be another time.

For now all it needs is the black paint job and a few small details here and there to give it some bling. That's happening soon.

Well all. Let me know what you think about my project RATROD. Good, bad, brilliant, obtuse, inspiring, moronic.......lemme know. I'd like to hear from you!
Cheers.
G.

I love those fat slicks, but the ones I tried were ****in heavy. I used them on one 15 mile ride and ditched 'em.

I gotta admit, I think its pretty cool! I had one of those as my first duelie, my friend bought it originally and we've passed it back and forth a few. Maybe its my turn to get it back! I have the original fork (that would polish up nicely think it's a Noleen?) original wheels (cracked eyelets don't know why I still have them) and a few other bits. Those bikes were pretty popular when I started MBing.

Nice nostalgia, good times.

I'm a Proflex enthusiast, but I gotta say - I love the fenders! You can get replacement elastomers for that rear shock from a place called Rapid Descent Scotland, and Risse makes a nice air shock replacement. There are also ways to adapt cheap-on-eBay used Fox shocks to work on the rear as well. Check out some of the info on this forum for more information:

Hope this helps...nice ride!

I'm not sure if it was from those Rapid Descent Scotland folks, but I ordered a spring replacement kit for the elastomer for a customer's 855. It was fantastic, and he didn't have to worry about his elastomer turning into a gooey mess in ten years.

Very nice! A rat rod in the truest sense. I've always thought that full squoosh bikes had a "moto" look to them and have wanted to involve one in some kind of project.
