1986 Fat Chance Titanium, Monday, April 22, 2013

One of the highlights of this past weekend was getting to spend some time working on and ultimately riding this wonderful 1986 (built in 1985) Fat Chance (I use the name loosely here) Titanium. For the record Chris Chance will tell you this is not a Fat Chance, but rather Gary Helfrich's first Titanium mountain bike. It just so happens that Gary was working for Fat City at the time he built the bike and so it shares its basic geometry with the Team Comp.

This bike represents a major turning point in the fabrication and material choice and fabrication techniques used in mountain bikes. Although it's tough to prove this statement, those in the know feel that this is more than likely the first ever Titanium mountain bike. Merlin is largely credited with being the first company to manufacture Titanium mountain bikes. Gary Helfrich was one of the three founders of Merlin (along with Gwyn Jones and Mike Augspurger), so logically if he built this bike before starting Merlin it would be the first.

The frame is constructed from straight gauge tubing with a wall thickness of 0.041"for the main triangle and 0.032" for the stays. Head tube and seat tube angles are both 72 degrees. Since Titanium has to be welded at very high temperatures and bathed in an inert gas to prevent it reacting with Oxygen Gary had to employ Plasma Arc Welding, a relatively complex and complicated process for the application. The welds on this bike are much more crude than even on a late 80s Merlin. It seems that Gary and the team at Merlin quickly mastered the process.

The best way to describe the ride characteristics of this bike would be to call it compliant. It's very pleasant during the climb, feels planted and efficient. It tracks well and is easy to handle and change direction. Although I'm used to lighter bikes, at just over 24 lbs it must have been a breath of fresh air to the riders at the time. Chris Igleheart raced the bike for a part of the season and commented that he loved the effortless way it climbed, but was definitely afraid of it on the descents. I'm sure the noodly box crown fork (which he welded!!) didn't help. This fork doesn't have the reinforcing gussets joining the legs to the box crown as the alter forks had. Although I didn't have a chance to take the bike out on any real trails, I definitely feel that it could get a little squirrely on some seriously technical terrain.

Rather unique and uncommon for a Fat rear entry drop outs. Whether due to user error or for other reason, the rear kept slipping under heavy load resulting in the tire rubbing against the seat stays.

Not a lot of tire clearance here!!

Very pleasant cockpit. I loved the early Magura motorcycle levers!!! Fun fact about early Magura levers. Maybe some of you with old bikes noticed you seems to have two left hand levers on your bike, i.e. the Magura logo is upside down on the right lever. Turns out that early one Magura only used long reach levers for clutches and short levers for brake applications. So bike builders had to buy two clutch levers and flip one upside down to get long reach levers for mountain bikes. Hence most early vintage mountain bikes have two left levers with one being upside down.

Detail of headtube which was stretched to accomodate the headset. Evidently tubeset selection was very slim back in the day, so both the bottom bracket shell and headtube had to be stretched to fit the application.

Notice the lack of inside gussets on the box crown fork. The yellow fork combination was later repeated in one of the merlin catalogs, a tribute perhaps??

1986 Fat Chance Titanium, Tuesday, February 5, 2013

Every now and then I have the pleasure of working on something really special. At the moment I'm assisting a friend with some minor restoration work on this beautiful 1986 Fat Chance Titanium. This is the first ever Fat Ti bike welded by Gary Helfrich before he left Fat Chance to start Merlin. Arguably, this is the first ever Titanium mountain bike, who knows. The geometry is identical to the Team Comp right down to the box crown fork. Gary built the bike to showcase what he could do in Titanium and when Chris said it wasn't something he was ready to do Gary left and started Merlin. The rest as they say is history.

Since the bike is in such good shape I'm merely assisting with some build details and component selection. As I mentioned the frame was welded up in 86, but the bike was assembled in 87. So, the parts are a bit of a mixed bag of M730 XT and some other bits. Planned changes include Specialized yellow label Ground Control tires, M730 XT front brakes, older Turbo or Avocet Racing seat, maybe black M730 cranks (doubt it though), some adjustment to housing lengths and a general tune up.
