Hi there folks
About a month a go I decided that my 1994 Proflex 754 (that I have owned since 2000) was getting a bit difficult to get spares for ie elastomers it was also a medium size frame approx 16" not ideal as I am 6ft 2" so a bit hunched up and massive seat post (I am also getting a bit older) couldn't alter stem on front Girvin 1 as it was fixed to the shock mount,
she was nice ride with lots of interest from other cyclists.
so after some research a decision was made to keep the faith but look for something a bit newer and larger.
So after some searching I sourced from the bay a 1997 857 expert series large size frame and rear triangle complete with NR2 rear shock
all seems in good condition for £70
I also bought at the same time a small framed 13" Gary Fisher bike that has donated for its groupset wheels and Manitou forks to the cause
857 spec now
1997 857 expert series large size frame (red)
with carbon fibre rear swinging arm and NR2 shock
2004 Manitou Axel elite (100mm travel) forks
2004 LX Deore mechs and shifters Mega 9
2004 Deore disc hubs 32hole no discs fitted at moment Mega 9 34/11 cassette
1997 Avid 1.9 levers and 2.0 V brakes (EX specialized FSR)
2004 Bontrager select crankset 170mm
2010 ISIS bottom bracket
2010 Cane creek S3 headset
1997 Specialized team control 2.0 tyre front/ Specialized team master 1.9 rear
2004 Bontrager 60mm 10+/- stem
2004 Bontrager riser bars
1992 Control tech seat post
1991 titanium flite saddle
Okay that's the bike introduced
I used ride more in the early nineties but got married kids the usual stuff to stop the big bike spends but am getting back into things and have been wanting to get back up to speed with MTBing whilst still enjoying the RETRO look
looking for more info on rear shock updates rear disc mounts (cant see drawings on this site) and have found both retro bike and IDriders a good source of info.
wiil post some pics soon of bikes in gallery

Welcome Pete97857 ,
Nice to see another proflex spring back to life.
Quite a few people have mounted disc tabs to their carbon swingarms. Same with shocks.
Somewhere hiden in the archives is a drawing for a disc mount. One gent even welded one to his carbon swingarm(Simon).
There is also greasing and parts info available, so ask away. ;D

You've done well, I approve. Now you just need to save up for a camera. ;)
-
Got the camera just a bit of a ludite when it comes to uploading photos,
will try again tomorrow didn't want to waste to sunshine so took the bike for a 2hour test ride along local cliff paths overlooking the sunny northsea Allen keys spanners screwdriver etc etc in backpack.
As you may have guessed brakes and steering worked well,still need to fiddle with riding position need 100+mm stem+10 and think that solid cable runs to rear brakes and rear mech is the way to go this will also fill the large cable mounts that came without spacer ferrules currently using bmx bike brake adjusters as intended to get spacers made up in alloy.
Back to rain again today that's Aberdeen folks

Comgratulations on the new/old ride! :) The 857 is still a pretty lightweight and capable bike, even for a "Retro" bike. Sounds like you have a decent enough setup already, but as you already have disc hubs then maybe fitting disc tabs is the next logical step forward? It's certainly the way I intend to go as even the Maguras are just not the same as a well sorted hydraulic disc setup.
-
shovelon can weld disc tabs for you. ;D He did mine:

...oops...how'd that last one get in there? ???
;D

I wonder................... Is she Schrader or Presta?

I wonder................... Is she Schrader or Presta?
Hmmmm,
Based on the fingerless gloves, I would think road, which would lead me to presta. :D :D
-
With a 23t cog?
-
Who uses Schrader anymore? All my tubes are Presta.
Maybe the 23t was her low gear, and she's so elite now that she doesn't need it for riding?
EDIT: Wait a minute...you COUNTED the teeth??
-
the clue is in the little bit of writing you can see on the dress just below, well, :-[ anyway, you can see it says Kenda 28 x 1 3/8 (I think). Roadie surely.

Hi guys sorry to be offline and unable to post pics of my proflex 857 but the day after taking photos and getting them up loaded I was involved in a sixty foot fall leaving me badly injured both feet smashed lots of bone damage to legs broken pelvis spinal fracture two broken wrists one smashed elbow and some broken ribs,
Good news folks I wasn't on my bike at the time of accident now after 6 months in hospital slowly getting better and now having Internet access (some hospital equipment affected by signals) here is the photos.
I will keep surfing for more information about the super proflex brand and try to spread the word should be back in the saddle in about one year.
Heres the link

Thanks for all the replys so far

Ouch!!! Yes, my first thought was.... "How is the bike?" During my years as a roadie-racer and mtb'er and EMT-fire medic the first words were always, "How is my bike..." though spleen was hanging out the nostril and feet didn't point in the same direction, the foremost worry was the machine.
I expect that had the bike been involved, you would have gotten much more air from which to plummet earthwards.
Wow, that is an impressive bunch of trauma! I won't soon be comparing scars with the likes of you. Not riding for that period of time will surely suck. I hope that your recovery can remain interesting and therapy brings a full recovery of your physical aspects.
-
Jezz Pete.
Hope you get out and about real soon.

was that 60 foot horizontal or vertical or combination? I had a horizontal one like that back in May but yours sounds a lot worse...
-
Holy crappola Pete :o how the hell did that happen?
Sounds like you're going to have plenty of time on your hands (I know what its like having a long time off the bike), so you've no excuse not to do your research and get your bike tip-top for that day when you can at last go for a ride in the countryside ;D
Best of luck :)
-
That sounds serious and it sounds like you were very lucky! Get well soon

Hi guys
Such interest in injurys typical bikes fall was caused by bad balance and to much lack of fear whilst out with some mates for a few drinks tried to walk along bridge parapet iv done it before and got away with it but not this time.
The facts sixty foot bridge I'm 86kg and landed on feet one a bit before the other left leg hit first I think(i don't remember the fall or next day or four) one of my mates who is good with numbers says impact 20+ mph not that fast but enough over a small suffice area.
Lessons learned the NHS is the best in the world and falling sixty feet HURTS you and your family big time.
So guys live life on the edge but make sure it's not to high.
Ok back to Pro-flex theme been surfing the net and picking up some NOS Pro-flex stuff seals / bearings rear dropout hangers black red and polished alloy
Slowly getting nice XT 739 mechs and other bits to have if I want to return to stock not sure if I want full retro or updated so if i have both all the better still looking for drawings for rear disc mounting not to keen on getting alloy part of swinging arm welded so it's bolt on plate ori have seen alloy arm yellow as stock but not sure if that would fit frame mounts(pivot point)etc but should be easy to make and get plate made and welded.
PS if you want to stop smoking get put in hospital for six months getting fed morphine it works.
-
Not sure if it would work for you but there may ba a chance of getting some rear disc mounts made.

It lists the 1000 model in the instructions which I think is the same frame as the 857 so it should fit.
