1991 Yeti ARC - Johnny O'Mara (O'Show)

Well, it seems that being the runner up remains the story of my vintage mountain bike collecting career. First it was the (supposedly) Tinker backup Storm Adroit and now the O'Show test/training or backup race bike Yeti ARC. Well, might as well own it..

I came across this frame on a German mountain bike forum and while everyone else was hotly debating its merits as O'Shows bike or not, I went straight to the source who quickly confirmed that it looked like one of his early test bikes. So, I quickly pulled the trigger. Four months and three cross Atlantic trips later (thanks DHL) the frame showed up at my doorstep.

At the end of the day this is not much more than a very early ARC. Serial number is A188, which means it's approximately the 88th ARC ever made. The only unique mechanical feature of the bike are the early, apparently hand made cable stops on the downtube. They are a less refined version of the same components found on later ARC, more blocky and less refined from a manufacturing perspective. The last bit are the pair of Johnny O'Mara stickers. Now, anyone could make a set of those stickers and put them on any ARC. However, I don't think that many people knew that O'Show raced for Yeti and so if someone were to knock off a race bike they would have been more likely to do so by putting on Furtado's or Giove's name on it. By the time the ARC series of bikes came around Yeti stopped the practice of welding the initials or name of the racers onto the BB shells and the stickers were the only thing that separated a race bike from one you or I could have bought. So, in the end I think the fact that this is an early ARC (O'Show had his big race season in 1991) with some pre-production elements lends credibility to the claim that it was his bike.

Fairly basic cockpit by Yeti standards, not sure about the grips - might swap out for black ones in the end.

Pre-Answer Doug Bradbury made Manitou forks. A whopping 1-1.5" of travel (depending on the temperature) is not much by any standard, but it made the bike a little more compliant.

Cook Bros RSR cranks add a little bit of flair to an otherwise fairly subdued build.

Not sure why someone thought a security screw (without the security cable) was necessary in this location

Apparently this is not the correct orientation of the Hyperlite bars, learn something new everyday. Early version of a team cut ATAC stem, the only clue to the age of them stem is the flat cuts on the ends of the cable guide noodle, later ones had a bullet shaped end.

Early decals almost appear hand drawn on the back of the clear vinyl, reminiscent of the earlier FRO decals from the 80s.

Here are some pictures of Johnny's actual race bike from 1991. He won the NORBA Expert class that year!!! Not bad for someone who wasn't a professional rider, he's still tearing it up on the masters scene today!

Notice the mismatched silver/black brakes and hub, I think I've seen this done on other team Yetis in the past.

This is a promo shot of Johnny's bike from before the start of the season, you can see it was a little more color coordinated and didn't have the team cut A-Tac stem.

The future of vintage mountain bike scene

I try not to present myself as any sort of expert when it comes to vintage mountain bikes (admittedly, I may not be that successful at this) as there are people who have forgotten far more than I'll ever be fortunate to know. In the end, I'm just a guy with a room full of old bikes and I simply do my best to keep them and myself shiny side up. Regardless, I often get asked for my opinion about where the vintage mountain bike scene is and where it's going. I must admit the question is one I think about often. At the risk of being cliche, in the words of Mos Def

You know what's gonna happen with Hip-Hop? 
Whatever's happening with us
If we smoked out, Hip-Hop is gonna be smoked out
If we doin alright, Hip-Hop is gonna be doin alright

I think it's pretty obvious that the current popularity of vintage mountain bikes is largely driven by nostalgia for the golden age of mountain biking. The age range of the vintage mountain bike enthusiast is between 33-48 (based on web traffic to sites and forums), which is about right given that many of us were in our teens or early 20s when the sport blew up. So, it makes sense that we're trying to capture or recapture a little bit of that wonderful time when the bikes were simpler and maybe more elegant and the sport itself seemed a little more approachable. Or maybe we just want what we couldn't have back then. Whatever our individual reasons, we scour the internet, pinch our pennies and spend countless hours working on, riding and in the end mostly just talking about the bikes and people that made the sport special in our time.

So, is all of this sustainable? Are we in a bubble? Does it really matter?? There is no simple answer to any of those questions - well, except maybe the last one. But that's mostly a personal issue anyway. 

Personally, I'm not old enough to have the experience of being part of any other group collecting vintage things. I've heard many stories and accounts of how cars, motorcycles or even cameras and calculators went through phases of desirability and collectability. Some have become mainstream, while others have faded into obscurity or altogether disappeared. Obviously the closest analog for vintage mountain bikes are other bikes- road or BMX come to mind. Both road bikes and BMX enjoy a vibrant collecting scene, with events, shows and a lot of resources for collectors.  But even then, bicycles in general do not have the same ubiquitous presence as cars or motorcycles. There isn't a central governing body that puts on vintage events, stages shows or otherwise promotes the hobby. In regards to mountain biking, that makes a fair amount of sense, as the roots of the sport itself were a countercultural movement, so celebrating that spirit by wrapping it in a blanket of classifications and formality seems kind of wrong. However, sometimes you have to evolve to move forward. 

I feel that some more structure would be a positive step forward. By structure I mean some classifications for what is considered vintage and maybe some delineation of subsets of classes. This has already been done in some areas, but rather informally. Many forums have a cut-off of '94-'96 for what they accepts as vintage, and some races with vintage classes make a break at '86-'87 to create two classes. So, the framework is there, but it could use some more clarity and definition. 

Why is this good? Well, in my opinion, this would create a guideline by which event coordinators for bike shows (like NAHBS, for example) or mountain bike races could stage classes for competition. Getting recognition for vintage mountain bikes at shows, races and in publications is an important step in teaching a new generation of riders about the background of the sport and possibly bringing a new cadre of collectors into the fold. After all, what will happen to all of our precious bikes in 20-30 years when we can no longer care for them? We need to have someone to pass on the torch. 

Going much further beyond that right away may be difficult and only serve to alienate people. While many of us may wish to own a fancy race bike, not everyone can - for a multitude of reasons. So, while some people strive to have the one bike they couldn't get back in the day, others are happiest re-acquiring their first bike. Who's to say one is better than the other? When it comes to measuring one bike against another, we have to remain objective, so our personal feelings can't play a part. This is less important in races, as someone can race on a fancy bike and get their ass handed to to them by someone hammering a Rockhopper. It simply comes down to "ride what you brung." However, if vintage bikes are to have a place in bike shows, then some further guidelines around classes of bikes or other means for judging one bike against another would be helpful. Potential classes could include: catalog spec (for the purists), race bike replicas (for the fanboys), or maybe a catch-all open class for those who feel that most bling is best.

The main problem with this is the lack of a central governing body. While there are several main forums where vintage bikes are shown and discussed, the opinions about what's right and wrong or good and bad vary dramatically, and I can't imagine all groups aligning behind a single voice created by one of the forums. Perhaps something like the MBHoF could pull together and curate more than a museum, but I don't feel that the will to do that lies within that organization. Alternatively, one of the larger publications could start the conversation and create a set of guidelines, but again I'm not convinced that any of the majors harbor that desire. We may need a new party to emerge with not only the will, but the respect of the broader community and the ability to evangelize the message. 

We've done fine for almost 20 years without any such organization taking hold. So, why now?? Well, maybe the period of nostalgia is running out of time. Many of the collectors who have been around for 10+ years have completed their collections, or are about to. Perhaps only now we are seeing a critical mass of people interested in vintage mountain bikes and the start of a broader recognition of the importance of the early bikes and their riders. If that's the case, then the time is right to take a step forward and ensure the continuation of the hobby.

Yeti Tree Frog trials bike

This little bike has caused me quite a few headaches over the past 2+ years. What seemed like a relatively straightforward project has ended up being one of the most complicated and involved builds I've ever attempted.

This is how the bike arrived

Relatively little is known about the Tree Frogs. According to some former Yeti employees maybe ten or so were made. Most were made for the team riders like Clint Knapp, but a few were built for paying customers. Although I don't know for sure, I feel that the number of custom modifications and the few parts that came with it indicate that it might have been a team bike, or at least an employee bike. It did come from a former Yeti employee, but I don't think he was the original owner.

Bike/frame details

No serial number
100/115mm hub spacing
Double wishbone reinforcement gusset
26.8mm seat tube
Front U-brake, rear cantilever mounts
Ovalized top tube, smaller than standard FRO
1 1/4" headtube
Round down tube, no braze ons
Rear wheel - Custom hub, unknown rim, 2.5" Pirelli tire on a 19" rim for an effective 20" wheel
Front wheel - Bullseye tandem hub, Monty trials 20" rim, Pirelli MT14 2" tire
Bullseye 135mm cranks with custom made spider
Shimano XT brakes and levers
FTW made stem and riser bars

I happen to have another Tree Frog here which I will show soon, but I just wanted to mention a few differences between the frames.

115 rear spacing on this vs 135 on the other
Double wishbone gussets vs none on the other
Rear cantis on this one vs U-brake on the other
No serial # on this vs T5 on the other (I know of T2 as well)
Rear stays appear to be two piece on this one vs. single on the other (perhaps to accommodate the wider 2.5" tire - I'll confirm)

Double reinforcing gussets. Only other bike like this is Chris Herting's personal FRO.

Reinforced brake bridge, not sure it really adds anything, but it looks cool.

Ovalized top tube like most Yetis, but this one is a bit shorter than the other TF I have, which is more like a FRO or Ultimate.

Custom rear hub appears to be a loose ball bearing hub that was converted to run cartridge bearings using a sleeve style adapter to fit 6001 series bearings into the shell.

This particular TF has taken some hits

Super cool brake setup allowing the use of a U-brake and increasing leverage

The stem is a replica of an actual Yeti trials stem

Super wide Pirelli tires were actually made for motorcyles

I'd like to find a more appropriate seat and maybe get some custom stiffener plates for the brakes, but for now this is pretty good!!!

Here are a few pics of another team bike in action back at the 1990 Worlds:

This is TF 2

This is the original prototype (no idea as to its current whereabouts)

Here is a Tree Frog that Yeti showed at the 89 Interbike

There are a couple more that I know of including two from Aaron Faust bikes and one more "production" bikes. I'm working on getting some pictures of those.

1991 Steve Potts CCR

The cult of WTB and all things NorCal has long touted the work of one Steve Potts and some of the best there is. Of course like most good things one of Steve's bikes is not easy to get a hold. I was quite lucky when a good friend who happens to be up at night pointed out this bike on eBay in a very attractively priced auction. The bike was being sold as local pickup only, and it just so happened I was travelling to that part of the country the following week. This is how I found the bike living in North Carolina, still with the original owner.

Although the build left a lot to be desired all the important parts were there (Potts Type II fork and stem, WTB roller cam brakes) and it's easy to see that this serious race machine was just waiting to be put back on the trail. I had been saving some WTB parts for just such an occasion and had visions of an all WTB equipped build. Seems like something that any fan of vintage mountain bikes should do at some point in time. In the end the only part I wasn't quite able to source was the WTB fixed angle seat post. The final build which I raced this past weekend at the Keyesville classic consisted of Suntour XC-PRO drivetrain, Specialized forged cranks, WTB classic hubs on Bontrager rolled down MA40 rims, WTB Chris King headset, WTB Titanium handlebar, Suntour XC-PRO post, WTB SST saddle and Ritchey Megabite Z-Max WCS 2.35 tires.

This bike really just looks the part of a vintage race bike. What it lacks in flair and panache it makes up for in spades with elegant lines and subtle finishing touches. I'm a bit backlogged with my more formal ride reports, but I'll try to do that pretty soon. In short summary though, this is a really well balanced bike that feels very at home on smoother trails. I for one feel rather uncomfortable on it when things get a bit technical.

The WTB Ti bar came in days before Keyesville and was really the icing on an already pretty tasty cake.

This is one of my first Suntour XC-PRO equipped bikes, and either I'm not really good at setting up that specific brand of drivetrain or there is a reason it went out of production. I did eventually get it running, but was never really impressed with the overall performance.

These brakes are really something to behold. I think more than 50% of my bikes are now equipped with Roller Cam brakes and I am starting to really like them. Getting them dialed in is still something of an art form that I have yet to master, but I think I'm getting there.
