    Action Tec singlespeed

    Got a few days off from work last week and decided to convert my old bike. It still needs cog spacers but it was a nice day so I took a few pics. I tried to weigh it without pedals but it was so light it wouldn't even register on the scale...

    Also need a half link to get a better gear ratio now that I think about it.

    duuuuude.
    weight?
    I'm no weight weenie but IIRC those things were like 21 pounds back in the early 90's, fully geared.
    what's it sitting at?
    If steel is real then aluminium is supercallafragiliniun!

    Awesome vintage single speed! Lots of cool old parts. Stem could be a foot and a half shorter though.

    Nice Ringle' suite, there.

    My first SS was a converted Action Tec Curtlo with Grafton parts on it. Good bikes. That fork was ahead of its time. Too bad it never stayed more current tech wise.

    has anyone actually seen one of these? They do not have a picture other than some stamped or lasered cog sets for a geared bike.

    Hey everyone, I forgot about this thread so sorry I didn't reply sooner...

    The way it is pictured it weighed a little under 21 lbs if it had it's peddles. I weighed it on my super accurate $5 ebay luggage scale as it sits here and I know what the peddles I use weigh so I used a complex mathematical formula to derive the actual weight. I don't know if those tires are light or not - they're wire bead (stolen from my wife's bike but she knows about it now and she's ok with it since it saved us a few bucks).

    It was 23-something pounds when it was new with the gears, bar ends etc.

    I don't know what is up with that stem either. I don't know how many miles I have on this thing (there's a BUNCH) but I couldn't even ride it to the mail box with that stem now...I felt like I was leaning over a wheel barrel while wearing stilts or something. Weird.

    I tore into it a little recently, as you'll see below, and found a few things needing attention.

    Unfortunately the cranks are done in terms of being used on a bike. This is the third pair I've had of these that have done this. And I always use a torque wrench and follow the manufacturer rec's. Probably just used them up?



    Yeah, they used to be blue when they used to be new (and they used to be clean). But they weren't "turquoise" blue which offended my sensibilities at the time.

    Better get around to fixing this while I'm at it...



    Won' need this (or the tape but I forgot about the tape.



    These are not single speed grips, but I like the irony.



    Comparison of the old to what I'm going to try next.



    This was all a warm up for the real meat of the maintenance. Not sure if I should be doing this...



    Hey Sparty, if you read this I was wondering if you would give me a pass if I was to call this fork a shock?



    Yeah, I spent about half an hour looking for bearings on the floor. My son was nice enough to offer to help though. His price? $5.00 per bearing. This motivated me to look harder.



    This is right about the time I probably voided the warranty. I knew the "hydraulic" fluid in this thing had to be looking a little rough and I just couldn't put it together knowing this so...I tried to be analytical about it.



    Yeah pretty rough:



    I don't know what Russ puts in these things but since I probably wasn't supposed to poking around in these internals I figured I was on my own. I do my own MX forks and had a little Maxima fork oil laying around.



    It was taking forever to pick out all the bearings from the solvent so I accidentally thought of this.



    All cleaned and greased.



    Now for the test ride...

    Okay, it's a shock. All is forgiven.

    I have a blue ano'd Kooka crank (180mm) in case you're interested... cheap.

    Nice photo journalism.

    I have 2 of those pro-shocks, but I have not serviced them yet, and one has been in use for 8 years(!). It's about time though, thanks for the preview.

    sParty, it's a fork - unicrown even! The shock unit is removable (if you have a press...)

    Another update

    There pics at the bottom if you want to skip the boring dialog...

    I've been trying to get this bike set up again and it's been fun, but a little frustrating. Maybe somebody will have some insight...

    Using the parts bin I began to experiment with the bars and stem. As noted in the OP, the 130mm, -10 degree stem the bike was designed for no longer works for me. I don't know what changed with my body but I can't seem to ride it that way. Maybe I need more time on it because I'm just used to newer modern geometry???

    Anyhow, first day was a 100mm, +5 degree with a flat bar: too low and short. Numb hands, felt like bars were in my lap.

    Next day, added a 120mm, +5 degree, same flat bar: Still felt low, like a lot of pressure on my hands, this stem also strangely felt a bit long.

    So I then tried both combos with a low rise bars. Much better, but still couldn't get along with either stem length so figured a 110mm would do the trick.

    Today's ride with the 110mm, + 5 degree: Really weird. It felt like the bars were really high, the front end would try to over steer and wash out. The best way to describe it is like it wouldn't respond to steering input until you "broke it over" and then it steered too much.

    I rode for about an hour, doing 3 laps of the same circuit. I noticed the bars were rotated quite a bit forward. The more I think about it the more I think this caused a large part of my problem. The bend was more or less pointing back at my face rather than back at my shoulders or wherever they're probably supposed to point.

    So I changed that and I will try the stem with the -5 degree config.

    This is how it was set up for today:






    Remember when I said I was having trouble with the handling? Here's a little sand wash...I didn't pose this pic. And I know how to ride a bike. Something is wrong here.



    Thanks to Sparty for the hook up. I remember my Cooks cranks weren't exactly stiff; these flexed like they were designed to be suspension cranks.



    If you have any input or polite comments regarding the handling please let me know your thoughts. Thanks!

    How does it handle on pavement? If it's balanced and managable on the smooth stuff, the handling problem might be suspension issues. As you move the bars up and back you are unloading the fork...maybe it's oversprung now?
    Anywhoo start off by using a tire combo that you know and like so that doesn't play while you dial in the handling. peace K.

    IIRC your other builds (or at least the raw rockhopper) don't have as much disparity in saddle/bar height. Maybe try a stem/bars with more rise?

    good point, i definitely can't ride with the bars that low.

    Thanks for the input, rode it again yesterday and things are getting better...but there's something going on with the old school geometry. I actually lowered the bar by flipping the stem but also was able to lower the seat due to the 180 cranks. The front wheel didn't want to "flop over" like it was, and I think I needed to sort of re-learn to ride a 26er. The 29er seems to steer more with the front while I found that the 26er is more rear steering. Instead of weighting the front so much I focused on putting a bit more weight on the rear and placing the tire where it needed to be rather than steering where it needed to be. May not make much sense but it is sort of like riding a 2-stroke MX versus a 4-stroke MX.

    I'm finally starting to get this thing dialed and I'm pretty stoked.

    Old school geometry... Remember when all the magazines described this bike or that as being "NORBA" proven race geometry. I rode a racey trek back in the day and can't imagine how I ever made it work.
