    All things Koski

    I know there was some discussion on the other threads about starting this so lets see what info we have as a collective. I personally would love to see more pictures of the Pro Cruisers, Steel Trailmasters and possibly a complete photo of a Ti TM ().

    An interesting article to start










    Matts bike from Rim



    #19002 (19" #2) from the recent SF show and the info that went along with it (thank Hollister for that photo)

    Mark, great thread, I hope it generates more pics of those elusive Trailmasters. Loved seeing your bike at SFO. Only thing I own Koski is his fork. It's currently at the platers, so no pics. I do have a pic courtesy of JB.

    A 1982 article in Bicycling discusses the Koski contribution and includes a photo of Gary Fisher and Erik Koski riding together. This link is to a scan on the OldMountainBikes site run by Laffeaux.

    All in Due Time.

    Thanks for starting this...I posted some on Donny and the Pro-Cruiser on the Pro-Cruiser serial # thread because the discussion on the Vintage Swap got a little out of control and went down the wrong path a couple of times so it was closed. DK is at the center of this group.
    Thanks

    All Things Koski?

    I love bicycles but Donny has been making something even more fun since the early 70's.
    These are very easy to ride...Heck, your grandma could ride one.

    Good article CK, thanks for that, it's interesting to read what he has to say about all the bikes. Im surprised no solid photo of the trailmaster....there has to be some good ones out there.

    Here is the write up on the TM. I didn't realize they were that much, $1500 was a lot in '82

    "The Trailmaster uses Aluminum handlebars; these bars absorb more road shock than steel bars"

    I always thought Aluminum transmitted more road shock than steel? <<< generally speaking...

    Whats the story on the skip tooth drive train? Did they grind off the teeth? Was there a specific reason why they went with that? Strength of the chain maybe?

    no, that's bike shop myth. Aluminum, size for size, is softer/less stiff than steel. It's when you get to the large tubing like Cannondale and Klein that things get stiffer.

    That said, I actually really liked the feel of the Klein Attitude fork. They're stiffer than your standard 1" to 1/2" tapered steel fork, but compared to a Type II or Yeti fork I'd say they were similar which means they steer and brake well when ridden hard.

    Cool thread, MJ. I've always loved the Koski fork and the Trailmaster. You want Pro Cruiser pics?

    Two Koski forks from Sonoma County builders

    Nice thread Stan Lee. Here are two Koski forks from Salsa and Ibis. I believe these were fabricated by the respective builders, but I am not sure.

    Straight-bladed from Salsa (with PCC sticker on steerer), late 80s


    Curve-bladed from Ibis, late 80s

    Absolutely right, NSR. Wow, thanks so much for remembering that thread. I love that the OP posted up all those pictures too. His "gave up SS in 75" was a cool treat too.

    i like the duratrac fork quite a lot and think it's especially nice on the retro, for many reasons.

    Info and pic from the DKG site.
    DKG-Musem Page



    Koski Trailmaster bicycle - 1979 -1980
    The Trailmaster was certainly one of the first purpose-built production mountain bikes, after the Breezer, Ritchey-built Mountain Bikes and the Pro-Cruiser. The photo is of frame #1 taken at the Mint 400 near Las Vegas.

    One of the reasons I started DKG was to build this frame. Don Koski was a longtime motorcycling friend from high school and was one of the people I would go 'bombing' with on Mt. Tamalpais. His family owned Viking Ventures bike shop and Don and Erik were putting together the first mountain bike parts catalog. They wanted their own product line as well, and commissioned DKG to make the Trailmaster frames. We built the frame, fork and sub-assembly fixtures and only about 100 frame sets before politics ended the relationship.

    These frames featured internally butted head tubes and bottom bracket shells, 4130 tubing, TIG welded construction, an original rear dropout design that has been much copied since.

    The 'Koski' fork was based on a design I had done during the Trailmaster period, but didn't have the capital to produce.

    Curved and tapered forks on a Retrotec Classic is the only look that works for me.

    All in Due Time.

    If one notices through out the articles spanning decades the Koski's don't go around saying stuff like I did this, we did that or even speak out to correct things. They just stay out of it.

    To Stan Lee...The picture of the Traimasters in the moonlight was from a recent Derby and I did post it...The cool skip toothed Trailmaster was not my posting but the bike is owned by one of Donny's friends and we had it at the Biketoberfest booth last year.


    Here is a early photo of Donny on one of his bikes in around '76. Check the Moto-x Fox shox and the Redline double clamp stem!

    Are you sure about that being 76". The only reason I question that is the snowboarder in the background.

    Marc had 2

    Marc had a ranch in Castle Valley before moving to Moab. His Trailmaster (seen here) ended up in the SFO Airport Display.
    Here are two:

    Very cool photo Howley, did you take that? Do you have other pictures from that trip? From what I understood Norstad re-welded the headtube as a preventative because a few of the frames had cracked in that area (Matt's being one) and then Potts covered the work with Paint- is that true? Thanks for posting...

    Shots were taken with a Pentax SLR. I used B&W film developed with standard color processing that created a great effect. Marc and I switched off on ownership of that camera over a 10 year span. Not sure where the camera went.

    That makes sense. Interesting picture. It gives me the impression of wanting to zoom out and see so much more of what's in the picture....

    hey sandy, i don't have one, so apologies for the reply. BUT, i was wondering, (and again, sorry for the stray off topic) what is the cool bike just to the left of the trailmaster? it looks like it has a cam style front brake, and then some sort of scorcher style bars.

    i'll keep my eyes peeled for trailmaster decals.

    mark's bike just came back from the SFO show to our shop, and they (joe breeze) put one trailmaster decal on the drive side.

    How dare you speak off topic!! See you in hell NW.

    The bike you're asking about in the pic...I think its the Ham that everyone urged him not to restore so that patina could be preserved. But was restored anyway.

    I had a conversation today with Dave Garoutte. He told me that he personally completed 60-70 bikes, and there were a few frames that he sent directly to the Koskis for assembly. From the nature of the conversation, 100 total bikes seems like the upper limit, and even that might be a little high.

    After a Breezer, the TrailMaster is probably the most collectible off-road bike of its era, since Ritchey MountainBikes and even ProCruisers are far more numerous. In the draft for my book, I point out that the TrailMaster was a superior design to the Ritchey MountainBike, with a larger diameter tube set and a stouter fork. If those guys could have solved their production problems, one of them would be composing this post.

    upwardly mobilehome.

    sorry rumpfy, the bike you are referring to was probably #C which i wet sanded, waxed and sold to the shark two years ago. my cunnningham is in the process of being repainted, #7. the bike next to my trailmaster is my cook bros. which is the first bike i bought from neil murdoch. it had a ta triple, new winner 13-32, atom drum brakes,magura bars and levers and a b-72. it has a cunningham type two with roller cam and hi-e hubs. ti seat post, and cruiser bars that i got from jack widmer at vegas in 2001. see this in the cruiser thread. and i am sorry #C had to go. he loves it, which is some consolation. i am in a quandry, as i'm not that fond of the color my #7 was painted in. would it be offensive to you if i were to paint it a different color? this means a lot to me ( sorry to speak off topic). i just can't see red snakes on a purple bike.

    Hey Sandy- As Nate said, Joe put a decal on the Witz bike that he got from Erik which means I have an extra. If Erik doesn't want one back I'm happy to send it your way.

    From what I understand sometimes they made it to the tt and sometimes they ended up on the dt depending on the day/customer.

    Inch-Pitch Trailmaster?

    Hey Sandmangts,



    The Trailmaster with the inch pitch set up was built by a kid from Bolinas California. A lot of kids that grew up riding dirt on Mount Tam were hooked on the pre-war drive trains.. (Skip-tooth Morrow and such). This guy had the coolest idea of how to stay with skip tooth and keep it light! He used an old set of aluminium Campy track cranks. I think guys raced skip-tooth on track bikes into the 60's....with block chain to boot! The skip tooth sprockets are 3/16" thick. That is one trick Trailmaster.

    You definitely document everything pretty good...if you have the serial number from yours, we can tell for sure...thought based on what I know, pretty sure its not a stolen one.

    Naugh...the last time I saw a sus fork like that it used bungee cords.
    DK had a telescoping moto fork sorted out for the frame...Probably off a Hodaka ACE 100 or something.

    I used to know a guy in NYC in the early 90's with an American Breezer with those decals. He was the original owner, the frame was hard anodized and had a custom American drop bar stem for a WTB bar.

    I believe that he also knew JB somehow, but I always thought those decals were "as shipped".
    Don't call it a gooseneck.

    It looks like that add is from the late 90's early 2000's. Rim brakes, Hayes disc mounts option, no mention of 700c or 650b wheels ect. It would be cool if it was 2013.
