The Red One...

Goes to the owner of Flagstaff's oldest bike shop: Cosmic Cycles.  If you wanted to buy a Ritchey mountain bike in 1984 this was the place.  All sorts of delicious bicycles have floated through this shop and pictures throughout the generations support that claim.  If you wanted to see a Mantis on the floor in person, this shop had one circa 1993.  A fat chance, yeah that too.  There are still some old relics to be found in there, and maybe the red one will be among them one day.  For now though it'll get ridden down Arizona's worst single track, floating over what all those guys breaking all those bikes of yester year never thought possible.  We took a preliminary ride down Private Reserve, one of the nastiest, and I never saw the red one nor its pilot.  Not surprising exactly.


The build is 1x11 with a 142x12 thru axle in the rear, Race Face Next 30mm cranks, A 140mm Revelation on Protection 2.4x650B Trail Kings mounted on a nice set of DT 30mm wide downhill rims.  Thomson Dropper post cause I just had to.  The geometry is pretty modest and modern.  Not too low not too slack, but none of that NORBA either.  Pure Flagstaff evolution.



Handlebar and headset spacer....possibly the most carbon to ever adorn one of my bikes.  There have been a few with cabon bars, and a few with carbon spacers, this is the first to have both.  The spacer matches color so closely to the King pewter anodizing I had to do a double take when we built it up.  Funny thing about the little details.  If you ever want a guy that isn't me (or you) to part up one of your frames, Scott is your man.  


The cables stay outside the frame because I worked on Kleins in the 90s and it wasn't as fun as you wanted it to be.  They were good looking bikes, but that's a rant for another time.  

Enjoy the Red Sled Scott, and may there be many rides to come!

Here's a Flyer

It pretty much has it all.  I'm there.  Sounds like Planet Sandwich is there, too.  Come see the latest crop of Moustache Rides and Troy's new REAL drum set.  I promise to wear him out during the set.


Hope to see you there!

The Widest Drop Bars Ever Made

I really don't know if there's any accuracy to that claim, but I do believe it to be true.  At 30.75" tip to tip I don't think anyone in the spandex community ever came up with anything that wide.  I usually try to talk people out of their existing dirt drops.  In Arizona they don't offer much to most.  Dirt roads turn quickly into the need for a real mountain bike....and most of us just aren't up to the skill that Johnny T had back in '88, nor do we have a Tioga disc drive sponsorship.  But Taylor came up with an idea that made a lot more sense and it kept his posture where it would be comfortable for days on end, and allowed for good descending on real dirt so I accepted the project.  


The idea was to maintain the bar angle of his Salsa dirt drops, raise the braking position 1", maintain multiple hand positions and allow for all day comfort and leverage of a 6'4" clydesdale.  The Shifters and brake levers are provided by Paul; it takes mountain bike parts and every inch of standard length cables.  His initial reaction to the finished product was much stoke, and he said they fit....both his hands and his vision.  Thanks for the cool project Taylor.  Ride far!

Re-Entry

Hacksaws and grinders; hand files, some emory, and a little one at a time at the vise.  One of these days I'll figure out how to set up the lathe for mitering.



Its a breather hole that is not drilled into the stay


The duck understands the concepts of "float" and "flight".....important when one's duty is regulating the back wheel of a hard tail that'll see many many miles.




I got to lace up some of the new WTB KOM rims...very nice.


Singles Speed Flagstaff style....don't let the parts you don't have keep you from riding your new bike...


....and an hour later....


The paint scheme is supposed to represent re-entering the atmosphere....The rider has been out in space for a while enjoying some future bikes.  Hopefully his return to earth has let him realize the advancements of the '90s.  Enjoy your new bike, Blair!

5th Annual Baah....

....My apologies to all for not putting out flyers for this year's event.  It warranted the smallest turnout to date for this Beaster Sunday celebration of all things feral on Mount Elden, though the spirit of past rides was loyally carried by eight returning goats.  Our annual tradition was overshadowed by an event much grander in scale and planning--The Big Zona Burlesque's Big Show.  It rightly robbed our ride of regulars who triumphed in a night of risque stage performance last Saturday night, showing off over a year of hard work by the many and diverse dedicated talents of our fine town.  Only one stage performer dared show her face on Sunday's heated bike battle, and both stage hands I might add, but all who did the ride were in attendance of both the Big Show and the after party.  The night's reigns were felt on the climb up Mount Elden by many if not all in attendance.  We set off without much a plan for the top of the mountain and a familiar starting point for the last five years.  There would be racing and a traditional start, Shotgun LeMans, but what?, leading to where?, we could not answer.  It was the year of the people's choice, and Blair's Birthday Baah.

The cake that emerged from Judy's pack at the top of the hill managed to pull peoples' eyeballs from the depths of their skulls.  The sugar seemed to stave off the general feelings of nausea.  Packs were heavily packed, and the load began to lighten as eerie spring rains encircled the mountain we sat atop.  It was warm and calm, atypical of this time of year, the familiar cold spring wind absent from our day.  We decided on a course...new to this event...it would take us all the way to the lookout tower for the start.  As you can see in the photos the course starts in a steep dirt road downhill that quickly turns uphill and then onto an extended section of trail known as the catwalk.  We decided to race the catwalk to Sunset trail down to the meadow and intersection with Red Onion.  


Typically the Baah is won and lost in the shotgun, and it has been those able to put this opening beer down, keep the burps down, and get down to riding that have won.  The (theoretical) trophy bears only two names from four years past, thrice of Mr. Heinchez, once of myself. But...there has been a challenger on the rise, putting up a big money run for the last two years....Austin, AKA, ????....wait this dude certainly needs a cooler name for this blog than his real name.  A close-up zoom of the above photo would reveal the positions for the hole-shot.  I pulled off an early gap in the guzzle and turned downhill.  It would not hold.  By the time the road bottomed out Austin, Heinchez, and Reverend Sham-pain would throw an attack into the climb that I could not answer.


A close look into the faces of the riders at this point would reveal no smiles.  A strange lull in speed of the lead group led Reverend Sham-Pain to capitalize on the hesitation as the others paused to hold back the heaves.  The reverend took charge into the very rough singletrack downhill.  It was his to lose, but none of the group had been up here this year, and the spring blow-down would inevitably turn the race in favor of the challenger as he followed the reverend down the catwalk.  A downed tree looked deceptively impassible.  The Reverend opted to go around but this was the deception, as it did not pass and left the Reverend hiking back to the route.  Austin opted for the direct line, and though admittedly sloppy, the log was hopped with a clear passage, allowing him to put on a lead that would hold for the rest of the race even while crashing near the finish.  In his third attempt at the Baah, we have a new champion!



The remaining riders, realizing that the race was over long before they arrived anywhere resembling halfway down the hill set back to enjoy the atypical spring day.  Positions were jostled without care.  Stoke for the day was exceptionally high.  And a new bike saw her first ride down the challenging terrain on Mount Elden met with grand encouraging smiles by her rider.  



There was talk of making it a stage race, all stages featuring the signature start.  But by the time we had all finished the stage that talk had ceased and the remaining weight of the pack was whittled down stop by stop through the rest of the ride.  We had quite a bit of downhill still ahead, but the difficult parts were now behind.  It was a perfect day, and all there was left to do was ride.  And tired though we were, none of us wanted to stop.

Ribbed.....

So I finally got around to making my special lady a bike....we've been massing the parts for a while now, and making notes of the setbacks offered by her former steed.  This one has the last main tubes of the old stock of Prestige tubing...they were just barely long enough to make a 650B downtube and they are ribbed....fluted I guess you could say. 1/10th millimeter variations in the wall concentrically around the top tube and down tube with a symmetrical and long butt profile.  The "up" ribs are .8 mm, the down ribs are .7 mm. 


The booty of this beast is all straight gauge aircraft tubing bent up in house.  Nick at Iron Horse did me a solid on the paint....I was going for a concept I called the midnight fade, but it ended up looking a lot like Shrek's girlfriend.....or a midnight fade.


First bike to feature a product of the lathe....44mm head tube rings.  I will never again think or speak of the way these were made before.  And as Paragon expands their selection of machined head tubes to include more and more sizes, they may altogether become a thing of the past.  Amen.


Full length housing on the ribbed top tube to a chainstay mount disc brake. 


This thing came out smooth!


Hope to have it built up this weekend.

What's Cooking in the Shop?


I had to bust out the vegetable oil and the ol' camp stove in the shop the other day.  Having the lathe around is awesome as it lets me work towards executing some ideas that have been back there for a while instead of just thinking about them.  This is the first step in what will hopefully be a game changer in the bike packing world....at least for my customers.  Paraffin is on the stove in the double boiler and the inside of the tapered steerer is oiled to allow the extraction of the mold. 


With the molds extracted I can now see the exact inner profile of the tapered steerer and measure transferred IDs fairly accurately and match the taper angle on the lathe.  Think back a little ways to the days of quill stem technology.  Confused yet?


Having the lathe around has changed the way I look at recycling.  Now its more like repurposing.  This old Phil Wood front axle sitting in the trash was too good to pass up.  Its already a nicely  machined piece of aluminum, though stripped threads rendered it unsuitable for further bike duty.


The threaded ends were parted off and the shoulders cleaned up, the fat parts turned down to 15mm to make some truing stand adapters for thru axle front hubs.  I should probably have thought to make the other side to 12mm, but since one of these hubs has yet to pass through my shop I just didn't think of it.


The Viking gave me this rusty old broken driveshaft of 2" OD.  Solid steel and about 25 lbs in weight.  Drilled a quick 15/16" hole down the length and got to work cleaning up the surface, turning some shoulders, and increasing that bore to 24mm.  


With the shoulders accurately turned to provide a width of a shimano bottom bracket with appropriate (and unfortunate) plastic spacers, I now have a dummy BB for mock ups.  This is for XT/SLX configurations and others that use that setup with the spacers.  Road and Sram stuff would have to be configured differently.  But no more threading and shoving to mock up the drive train and check for clearances.  



The last one is just a part of solving a problem I've been trying to work out on the Henry James Jig for a while.  I made the dummy tire from an old Jeep roll bar that's been sitting around the house since I moved here.  The bigger problem is how to hold the stays, both chain and seat for accurate tacking.  With the hand curved and hand mitered stays, fixturing them usually comes down to splitting the difference in the inconsistencies in the bends and cuts to where the eye can't tell if they're not exact.  I've been using the bridge and boss jig to accomplish this fixturing along with some tubing blocks and a piece of half inch rod, but the mounting point of this aluminum arm is inherently flimsy and poorly toleranced.  So if there's no great way to tell if it is centered, it makes the stay mock up out in space particularly difficult.  The dummy tire is probably a step in the right direction, but really what's needed here is a solid arm from the main jig plate.  Guess its time to buy a mill and start finding some aluminum block.  The machine era sure is sweet though, and the practice projects here turning out functionally is good promise that the real upcoming projects will be a success.
