Bike Check: A '90s Nike Airmax Inspired Steel Full Suss

BIKE CHECK
Michiel Burgerhout's
Project 12 Vertigo
Photography by Michiel Burgerhout


In recent weeks we've seen paint jobs inspired by heavy metal, hornets and even search and rescue planes but there haven't been many as striking as this Project12 Cycleworks Vertigo that was inspired by a Nike Airmax trainer from the '90s.

We've previously covered Project 12 for its Dutch Downcountry Victor but this is the much bigger sibling, the Vertigo. Rather than the 95mm travel the Victor frame had, the Vertigo is 153mm of travel with 27.5" wheels and is designed to tackle the bikeparks outside of its native country. This particular one belongs to a retro bike collector who was attracted to the straight steel tubes with fillet brazed joins from the builder Michiel Burgerhout, but to make it even more retro he added this wild paint job.
Details

Frame Material: Steel
Wheelsize: 27.5"
Rear travel: 153mm
Suspension Design: Single pivot
Head Tube Angle: 64°
Seat Tube Angle: 76.6°
Reach: 470mm
More info: @project12.cycleworks

It apparently took 6 months of sourcing and de-anodizing and polishing parts for the build to come together and then it was finished off with a paint job from Cyclepaint.nl. Even Michiel himself chipped in by swapping out his normal brass headtube badge for a custom machined aluminum one. Let's get into all the details.


bigquotesI've been a retro bike collector for about 10 years. I sold everything a few years back except for 3 bikes, but the retro vibe was still alive. I had the silver wheelset made for my Nomad as an extra set but never used it so that started the idea of a complete silver build like in the old days. The color inspiration came from an icon from 1990, the Air Max 90. I loved them back then, but couldn't afford them, especially the pink and blue color scheme. So I chose those colors and it came out as I envisioned.

A single pivot design drives the rear suspension. Note the stripped DVO shock as the green anodising would have been too loud even for this build.

 @hllclmbr: true
Titanium frames are also technically alloys with 3/2.5 or 6/4 percent chromium and vanadium (or is it the other way around…been awhile).
Either way no one but a troll or a jackass goes around referring to their steel or ti frame as “alloy”.

Back the day, if you had a 6/4 Ti Litespeed, you’d most certainly claim it was a 6/4 alloy bike, but you might also be a jackass.

 Having had AirMax back in the day, nothing about this says that to me. Doesn’t need that association to be cool - it stands alone, purple/blue fade and all. Reminds me of what a bunch of bike companies were doing in the early 90s.

 WTF does this have to do with a pair of shoes older than most posters on this forum? The paint job is slick, but seriously. Nike is a douche company anyways. They charge $200+ for a pair of shoes made in a sweat shop somewhere for pennies on the dollar.

 Yes, those are some of the thinnest seat stays I've seen in a long time!

 @RayDolor: Thin actually probably helps here (stay can flex a bit more). But it won't matter in the end, fatigue will win as the chain/seatstay angle opens up every time you hit a bump.

 Cracked one of the dropouts of the hardtail version in less than 300 km. Frame flexed like mad. With a shock attached to it and everything moving, and the same skinny stays, mad flex might be a bit of an understatement. Fashion above function!

 To each his/her own I guess. I love the flex of my steel bikes and I love my FS bikes. I just don't get steel FS frames at all however. I don't want my FS frame to flex in the slightest. And the aesthetics are just not there for me either, unless we are talking an old BMW.
  • 2 0
 My Cotic doesn’t noticeably flex at all, it does however provide a less harsh feel / feel more damped if that makes sense? Saying that it runs alu chain stays
  • 3 4
 What about when you're going around corners? In this case, at 45° lean for example, only half the bump forces act through the suspension, the rest act to bend the frame sideways. A compliant frames gives so much more grip and control than a super stiff frame.

Unfortunately you've applied an over simplistic idealisation to your understanding of how a bike works...
  • 1 0
 Agreed. A beautiful bike, but full suspension steel doesn’t make sense to me. For my DJ, and gravel bike, hell yes. Steel is my preferred material for those, but not full suspension.
  • 1 0
 @phutphutend: as have you. forces are predominantly directly through the bb to the tyre contact point. even with the greatest bike/body separation body position ( even pros dont display as much as the youtube 'howto' gurus suggest) your mass will be moving directly down through the frame/bb. maybe low speed then flex may help but who needs damping at low speed?
  • 3 0
 So many outstanding design solutions! And a really cohesive end result. It’s impressive how well you maintained the hardtail profile lines! Extra credit for your seat choice! Thanks for sharing

 That is an awesome looking bike. The frame details from the builder are spot on! The collectors version is quite the looker. My kind of suspension, gorgeous cranks.. and that silver “anno” screams to me early bmx before colored anno. Very nice bike!

 the fat stanchions on the shock and fork look weird paired with the skinny steel tubes. considering they spec'ed the ingrid cranks, i'd think that intend_bc's fork and shock bling would be right at home with this frame.

 Ingrid is quite a bit more affordable than Intend, and DVO is also very good. But the next Vertigo will be a full Intend affair.

 Just checked your profile - nice! I really like the crank arms. What's the process if I wanted to do something like this myself?
  • 3 0
 @ryan77777: For the crank arms I started with a wire wheel in a bench grinder to strip the black anodizing and then used an aluminum polishing kit from Harbor Freight to get the shine. Was quite a bit of work but I had a lot of time to kill! I polished my seat clamp (specific to Ibis frames so no aftermarket options) the thru axles, and a few of the other aluminum frame components. Those were much easier as they were already a smooth anodized finish, the cranks were a dense matte finish that was quite tough.
