For a newly acquired Yakota Grizzly Peak Tandem to ride with my kid. It is 7 speed shimano (below DX/LX) with push pull index integrated shifters/levers, cantis up front, U brake in back. It is ridable but I may want to upgrade a little. The flexstem is cool but I could use some new rubber bumpers for it. Threaded stem/headset. Are there any places to buy newer versions of these parts or upgrade them to Deore DX/LX??

For Flexstem parts try contacting Chuck at Pacific Coast Cycles in Oceanside, CA. He has those on a lot of the classic bikes in his shop, so I assume he has parts for them stashed away.

Hey, jimmy......I have a few replacement Flexstem elastomers laying around my tool room SOMEwhere......If you have no luck locating any, lemme know - I'm sure I could eventually find them - heck, I'll let ya have 'em for free (I think I may only have a few "hard" ones and possibly one "medium" left - can't remember, it's been so long. ) Back in the day, when it became hard to find replacement elastomers for sale, I'd e-mail the company and they'd send me 4 or 5 at a time, at no charge - did this a couple of times, so I had more than I'd ever use (and, of course, the Flexstem has been "retired" since I put a susp fork on the old beater).

 

[jimmy]

yes, could you?

I can send you a PM with my address, etc. This is my vintage tandem project. I am going to stick with the flexstem for now. Will ride trails, roads, dirt roads, etc with my 7 yr old in CO. Nothing too technical but we could ride in many of the good locations in CO.

Yeah I agree.

I saw a stash in his display on Saturday, I'm sure he can help you.

I called Pacific Coast Cycles. They said they had the other- Alsop- stem parts, not the Girven Flexstem. I have the Girven Flexstem. So, thanks for the help.

[Eastcoaster]

Shirk's in EastEarl, PA. They used to sell EVERYTHING Girvin, Pro-Flex and then K2. Luke Shirk may be able to help.
Shop Phone: 717-445-5731

Girvy's

Have a load of Flexstems...new, of course...name your price

 

[olds_cool]

cheap fix...

bushings from skateboard trucks. come in all durometers, too. we used them to stiffen up the travel for cross bikes back in the day.

 

[rutteger]

If the original poster (or anyone else for that matter) needs any flexstem spares one of my local second hand shops has a box full of NOS (but battered) 1 1/4" alu flexstems for peanuts. Give me a shout and I'm sure we can come to an arrangement.

HELLO, YOU SOUND LIKE YOU MAY KNOW A THING OR TWO ABOUT FLEX STEMS.
I PURCHASED ONE OFF EBAY A MONTH OR SO AGO, I WAS GOING TO PUT IT ON AN OLD KHS HYBRID, IT HAS THE RED ELASTOMER ON IT.
I PUT IT ON THE FLOOR AND PUT PRETTY MUCH ALL MY WEIGHT ON IT, IT DID'NT BUDGE. SHOULD IT HAVE???
I'M WONDERING IF THE ELASTOMERS DRIED OUT OR IF ITS A REALLY STIFF ONE , EITHER WAY, I'D LIKE 1 OR 2 REPLACEMENT ONES IF YOU'D LIKE TO SELL THEM TO ME. THANKS

 

[purdyboy]

I have a mint flexstem that I used for a while (actually, its back in its ORIGINAL BOX). The suggestion of skateboard bushings is a good one, I never tried it but new of others who fiddled with the rubbers.

Did you remove the pivot bolts and check the condition of the pivot? You may need to polish the 'bush' that the stem pivots on. From memory the bush was alum and would score if not maintained well. Polish, lube and reassemble - taking care to tension the pivot bolts so that the quill doesn't wiggle laterally but is still loose enough to pivot down smoothly. Play around until you get a feel for the right tension then pull out the pivot bolts (again) and reassemble with locktight on the (clean) threads.

I'll post piccies of the flexstem in its box one day for all you vintage bike pornophiles.

 

[TraumaARNP]

Have new flexstems

who wants them?
