    Koski DKG Trailmaster #20

    This one came to me as a frame + fork that looked like it hadn't seen much usage over it's lifetime.

    I've tried to build it up as I imagine it might have looked rolling out the door of Cove Bike Shop some 30+ years ago.

    Here are some odds and ends from the 1980 Trailmaster catalog that influenced the build:

    The 1980 Trailmaster catalog lists Breezer, Pro-Cruiser, Laguna, Cook Bros, and Champion frames, but not the Trailmaster frame (huh???) I didn't even know the Trailmaster/DKG frames existed until hiawatharider started this thread 30 years riding the same mountain bike several years ago.

    Magura Ergo grips with turned down flanges, Magura Shorty levers, Suntour thumbies:

    Headset seal - the one on this TM was originally on an early Ritchey built up at Cove. And yes I would agree with the "special formulation rubber" description, the seal was exposed to grease and grime for 30+ years and still feels pretty fresh.

    Cinelli 1A stem. I'll have to tell my son to try and remember not to launch any 50 ft jumps when he borrows the bike.

    Suntour VX derailleur modified for oversize 1.25" seattube. Apparently Koski would reform the FD clamp halves by beating them over an 1.25" mandrel:

    For this modification, the industrious E. Koski only charged an additional $3! Considering all the time I spent screwing around with the front derailleur modification, I would have gladly paid the extra three bucks!

    very nice bike! i know most trailmasters were supplied with the decal on the top tube, but i, too, like the look on the downtube. i wish mine wasn't 2,000 miles away. i'd ride it tomorrow. cheers

    I saw my first Trailmaster at a group ride in Houston this weekend. It was lab led as a 1979. Stunning bikes to say the least!

    Very nice! I too have messed around with that front derailleur mod in the past, and it is tricky to get right.

    Hey E- Still a bit of a mystery to me whether the frameset has been repainted or not. I am not expert enough to know just by inspecting it. I don't think I'd even be able to tell the difference between powdercoat and wet paint.

    My first impression upon seeing the frame was that it was repainted. It was the first TM I had seen with the newer-style split cable housing stops, and plastic cable guide screwed on under the BB. So I assumed that the stops were re-brazed when it was re-painted.

    But now I'm not so sure ... the split stops started appearing on early Ritcheys around mid '82. And EK was still marketing the TMs during this period as he was still posting ads in Fat Tire Flyer during '82.

    But you probably have seen the actual frameset and likely know more about its history than I do.

    I did get the bike out on the dirt for the first time yesterday. A bit doggish on the climbs but super-fun on the downhills. The wheelbase is 1-1/2" longer than the early Ritcheys, but most of the difference is front-center as the stays are about the same length. And the head angle is a bit steeper on the TM. Feels very sure-footed and predictable on the descents, although some of the difference may be the small block 8 tires, first time riding the dirt with those as well.

    It's not mine... The wife and I were out on a group ride on our vintage rides, neither as cool as this one or yours... What caught my eye were the wood balls on the tip on the bar ends and of course the TR bars.
