So, a couple weeks ago when this stunning Sky Blue 85 Mountain Klein showed up on eBay I decided to go for it. The bike looked stunning, a perfect time capsule. I was very excited to have won it, and for a rather reasonable price. I think the rack and the jacked up stem shown in the eBay listing helped keep the bike under the radar.
A couple minutes in the stand and the real bike emerged!
The build is as follows
85 Mountain Klein frame with matching fork (medium)
Suntour XC Stem
Specialized Aluminum rise bar
American Classic 27.4 seatpost
Avocet Touring 2 saddle
Shimano FC-6206 cranks
Shimano M700 rear derailleur
Suntour XC shifters
Suntour XC front derailleur
Shimano Dura Ace hubs and quick releases
Suntour Roller Cam brakes
Shimano M700 brake levers
Specialized Ground Control tires
Cunningham designed stem. Interestingly, Gary used Charlie's early stems on a few of his early road bikes, so it's nice to see he chose the licensed version of the stem for his early mountain bikes
Double down tube internal cable routing for the rear derailleur and chainstay mounted roller cam rear brake. The very early MK prototypes had a beautifully sculpted cable entry for the rear derailleur. Although very nicely executed on this bike, it's crude compared to Gary's first MK.
This is the only MK I've seen with a front roller cam brakes. Although not many are accounted for in my registry 100% have cantilevers in the front. Even the prototypes and MK001 have cantilevers in the front. In fact Gary's prototype has cantilevers front and rear. The RCs on this bike are the early design with drilled out arms, as opposed to the later dimpled versions. No expense was spared to build this bike back in the day.
Dura ace hubs were commonly used on mountain bikes of that era, but were not common on MKs. I've only seen one other MK in my registry that came with DA hubs from the factory.
6-spd rear cluster was the pinnacle of technology at the time.
The sovereign blue color is simply stunning. The welds just disappear into the paintwork, this bike may be rapidly becoming one of the favorite Kleins in my collection.
The Biopace chainrings on this bike are a bit new (date coded verify 03/86 production) so the bike received some cutting edge parts when it was built.
One of the more recognizable traits of a Mountain Klein are the square chainstays with internal cable routing for the rear derailleur. Gary started out with running the rear derailleur cable on his first prototype for the Mountain Klein and continued that design for the first two years of production. Sometime around late 86 early 87 he switched to an external cable stop and and a more conventional routing on the outside of the chainstay.
The junction between the BB and the chainstays is definitely overbuilt. It makes for a very stiff braking platform and provides some nice shielding for the roller cam brake. Unlike the prototype the welds here are clearly visible, although still very nicely done. Tire clearance is tight and I think you'd have a hard time getting anything over a 2.1 tire in there. Crank arm clearance on the other hand is pretty good and there is no discernible flex under hard pedaling.
Beautiful welds were something not seen on any sort of production mountain bike before the Mountain Klein came along. The welders at Klein were true craftsmen and produced some of the most beautiful and well riding machines on the market.
More beautiful welds.
Shimano 600ex headset fits this bike perfectly and looks amazing coupled with the polished Suntour stem.
