Here's Your Single-Sided, Carbon Fiber DIY Linkage Fork
@dfiler: I hear you, but those were all engineered to be single sided. That's different than taking an axle and hub that were designed to be supported on two sides and taking away half the support. It may be fine, but my intuition is that when you change something from double shear to single shear+bending you need to be damn sure it's strong enough. Bending is what breaks things.

@Rocksled: Hopefully you don't see the difference :D. I doubt you'll be able to sense a difference since the aluminum is probably rigid enough as is. The concern with aluminum is that it always has a finite fatigue life, regardless of the stress. With steel, as long as you are below the fatigue strength, it has infinite fatigue life. You can also get way stronger steel than you can get out of aluminum. Aluminum is also more notch sensitive than steel so those threads are going to be more susceptible to failure. I'd probably also loctite that sucker in there so it doesn't loosen on you at the worst possible time. Honestly, I don't think you need FEA done on that part of it. Some pretty straight forward hand calcs will get you a good idea of where you need to be since you're not really worried about weight savings or eeking out the last bit of stiffness. FEA on the chassis and the linkage may be a good idea at some point, or just keep it beefy AF!

@dirt-klaud: not to mention the lever arm acting on that axle when you lean the bike over is a function of the radius of the wheel and the angle of lean. Rail a berm on that thing with some brake bumps and you’ve got a serious bending on that axle. If it were me, at a minimum I would swap that out for a high strength steel or Ti axle before doing any serious riding.

I guess I'm the only one concerned about using a 20mm thru-axle and standard hub for this. The reason cannondale uses that funky axle and proprietary hub is to keep the wheel snug and withstand the bending moment that is caused by having a single-sided fork leg. That 20mm through axle is going to fatigue fail, it's just a matter of when. And the left side wheel bearings are going to get destroyed from the extra load. I love the ingenuity but I wouldn't ride that with any confidence.

Video: Matt Jones Learns the History of Marin Bikes
Eh, it's contentious but not quite that bad. Lots of people fighting the good fight and there is plenty to ride that is full on legal, and plenty more to ride that is full on "social." Overall I give the situation a D. For some additional perspective on this video: 1) Marin Bikes is headquartered in Petaluma, which is in Sonoma County 2) Their full sus bike names are hilarious. Wolf Ridge is a shitty fire road. Alpine trail is a short go-no-where hiking trail. Mt Vision does not have any legal biking trails, and the trails it has don't really warrant a full suspension bike. Rift Zone trail is a flat, I think even paved, fire road. Hawk Hill is a nice road ride. Their hardtail names are at least pretty reasonable except Nail Trail, which while fun on a hardtail, is way gnarlier than all their full suspension trail names. It makes me feel like their marketing team doesn't actually even ride in Marin.And based on the video, I don't think they do. 3) Oh yeah, their Friday company rides are also up in Sonoma county.

Jeezuss!! That spot where he was heading pretty much due west and then switched to south was amazing. So glad that compass was there to give me perspective!

Opening Day Survey: What People Are Riding at the Whistler Bike Park
@m33pm33p: Yes, if your chain is routed around a girl that will certainly slow you down. Because you wouldn't be bashing an entire gender for the sake of a 26 vs 27.5 argument, right?

What about the situation when you have a 26 inch bike and can't afford a new bike? Better to not ride?
