    Default Vertigo Cycles

    I was lucky enough to catch up with Sean (vertigo cycles) in Portland last week. I had a great time..and came home with this.

    Woah. Vertigo-fabbed H bar, I assume? That would sleep in my bedroom.

    The pictures in this post are all Sean's (who is Vertigo Cycles).

    This bike is kind of an envelope-push along the 'all-mountain' hardtail category genre. Sort of.

    In other words, it has a slackish front end, its long low and has a playfully short back end.

    It is also designed to clear 27.5x3" tyres and run a 120mm fork.

    It is designed for a dropper post, internally routed and also DI2, run internally as well.

    Some may follow Sean on various social media and will be aware of his super clean, internal routing solutions. Early on, he adopted 150/157 rear hubs for hardtails with flipped DM rings, custom spiders or 83mm crank axles to achieve excellent chainline and clearance for short stays. He innovated and established the 44mm external headset cup. Some may also remember the hard line rear hydraulic brake from NAHBS, Austin.



    This bike has some elements of this design philosophy throughout. I'll come back and update it soon.

    I saw two of these on a trail up here in Canada last weekend and they were stunning. I wonder if the two riders visit Vsalon?

    Do builders frequently work from 1:1 CAD drawings as shown in these photos? It makes sense if the object you are making is not too big, like a bike frame.

    There is so much proprietary stuff going on in these frames - the craftsmanship is incredible!

    a few more pics..

    The sweet stays are beautiful to behold, i think, but add some complexity to the task. The stays in this instance join the adjustable dropouts closer to the bb and the angle that the tube comes down to the drop out at means there is a small area to get the different planes of bends in. There is no room for error on where the bends are to clear the tyre for it to hit the dropout at the right point- you cant fudge fore and aft to make it fit - it has to be bang on.

    The 'Newton noodle' is the guide tube for the dropper cable from downtube into seat tube. reinforces the holes required and looks sharp.

    The DI2 routing will come through the slider mount. This Paragon piece is modified for a grommet.

    A few years ago, ti frames were usually brushed or polished or blasted. One could quip that it would allow some fairly average or even poor construction to be hidden in some circumstances. Nowadays, if you are good enough, the frame has no noticeable colour around the welds, meaning that an unfinished frame is the epitome. The welding needs expert management - distortion and contamination of welds is a disaster.

    Heat sinks are a part of the welding story and custom bb shells need their own sinks. For some reason, I very much like the look of a good heat sink...

    So time to weld. Tack, then first pass then second. Taped up to keep the argon in and a particular routine to keep it straight and avoid any need to cold set.

    The wheel is fitted to check.

    Then its time to make those flawless welds.

    So - why KRAKEN? it's not about the big sea monster - though this bikes fraternal twin is LEVIATHAN and i do have an interest in sea monsters - i'd suggest Kellie StrÝm's book if you do too.

    I have a penchant for over-land vehicles as well as bikes and there is a jeep I saw once called KRAKEN - with bulbous tyres and a disposition for rough stuff. The image was stuck in my head when 27.5+ tyres were becoming more established and I realised that it needed a dedicated platform rather than a bodged-to-fit bike.

    Anyway, prep:

    With the cables and wires in place, the junction box needs to be fitted to the bottom of the fork steerer. This small aluminium housing slightly compresses the bar end junction box improving the water resistance. With the port facing the ground and Shimano's own efforts to weather proof DI2 - it will be fine. My fork has a robot.

    Then it's a case of getting the wire to the robot...

    One more today:

    So - getting the wires to the junction box, in the steerer. How would you do that? there are some easy ways - through the steerer cap, or using a Tharsis stem for example, but Sean is all about the Super Deep Custom Shit - so he modified a Thomson stem and put a hole in the steerer of the fox 34 fork. Boom. It's alive.

    35239592424_3236cce4cd.jpg

    Don't worry, there was a lot of thought behind this.

    Drop the travel on the fork to 120mm - with a little lathe work to get the tools for the job...

    35690053920_5b983aeec3.jpg

    And we are nearly there....a few touches and some carbon loop bars. Oh, a saddle too.

    The Vertigo Cycles ambassador camp was in Cumberland, BC this year. The trails were slayed and product was displayed and tested.

    Ok, I'm kidding.

    But we did have awesome fun hitting the trails. Short back end bikes with dialled geometry and rocky, fast, droppy and swoopy-rooty-tooty trails lead to big grins.
