Let’s say we really wanted to ball out and be able to do lots of shocks as quick as possible and with crazy accuracy… 400 psi compressor +/-0.05% digital pressure gage T the high accuracy gage into a QD to schrader line and you’d be able to get pressures accurate to less than half a psi in no time. Lots...

From my experience with calipers, bolted vs mono block isn’t all that important as long as the bolted interface is done properly. That entails getting the fasteners as close to the rotor as possible and maximizing contact area between the two halves. Most the deflection should be between the joint/bridge and the bottom edge of the caliper regardless of how...

I don't believe that is what's really going on for a couple of reasons. 1, rubber generally expands much more than aluminum when heated so adding heat makes the seal fit tighter. 2, when designing our calipers we found that without compression played less of a roll with pad retract than you'd think. Too little compression creates sealing issues and...

Fluid volume itself doesn't necessarily mean more power. That's more dependent on the ratio of caliper piston area to master cylinder piston area. Adding fluid volume in the caliper does help with heat, but unless you make the caliper dissipate heat faster they'll still get hot eventually. This is why you see phenolic and ceramic caliper pistons. They insulate the...
I'd say impact on other aspects of kinematics beyond leverage curve are similarly impacted with horst vs other layouts for the most part. I've found with VPP and other layouts with two short links, towards the end of travel can deviate a lot. It's usually in a way that's, at least for me, positive (low anti squat and low anti...
When you install an MX yoke, you're increasing the combined length of the shock and yoke which is the same as installing a longer eye to eye shock on a non-yoke bike. It's pretty easy to visualize how that will impact the leverage curve from the standard one by extending the curve to the left from 0 shock stroke and...
Here are a couple of plots for you. The first is looking at how fast the chain length is growing. This is pretty much to compare how chain forces will impact pedaling between the two. The higher the number the more chain tension will try and pull the bike up in travel. On some bikes that number can go negative...

It's a time thing. Haven't shelved it or anything. Evil links require more tooling despite being simpler to machine once that tooling is done. We're a pretty small company so time is hard to come by.

This was thoroughly hashed out in the tech rumors. We blocked one person. The person that started this thread. Calling it a review would be a stretch. Calling it defamatory, not so much. Edit, seeing as you made an account today just to post one thing I’m going to assume you are that exact same person.
I don’t have my computer on my so I can’t dig up the numbers you’re talking about right away. I’ll gladly share them when I get a chance though. The reason they aren’t listed is because the change is imperceptible. Anti squat and anti rise largely dependent on axle path/IC and it’s hard to really change that without changing more...

It’s well known that the Druid and dreadnought share the same link. A good number of people actually installed it on the dreadnought before we ever listed it as compatible with the dreadnought. They were happy with it and we continued to get questions about it so when we got the shock compatibility to a place we thought was reasonable...

So looking at it from a conservation of energy standpoint, yes you have to slow down a rotating wheel. Where it gets interesting is when, assuming no slipping, you write out the wheels energy in terms of your velocity. Bigger wheel rotates slower. In the end the radius of the wheel is not included in the energy equation. This is...

Longtime NE Patriots coach Bill Belichick is a polarizing figure in American sports, but there's this quote he said that I love and can't get out of my head, "Coaches don't win games. Only the players on the field can win games. Coaches can lose games, though." That's what I think about bikes in competition. Bikes can't win races, but they can lose races. As such, my goal in setting up a bike is that it doesn't lose me the race, i.e. mechanical drag or inefficiency, mechanical failure, flat tires, inconsistent or unpredictable performance, major unpleasant tradeoffs, etc. Basically if...

I will forever remember the day when Cascade Components called me "sensible." I do wonder how much of the current trend of HBOs in shocks is affecting this whole discussion as well. It seems to me like we're moving more towards position sensitive damping in general, which would probably facilitate a longer stroke shock as well. I've always been under the impression that the longer the shock stroke, the more "tune-ability" you could muster out of it due to the length of fluid displacement. But I guess you could probably achieve the same thing with a short stubby shock with...

One thing I’ve always struggled to wrap my head around is what the right cut off for high speed and low speed should be. I’ve certainly ran into issues with impacts and where wheel speed is right around the crossovers, but it’s few and far between. Interestingly it’s with the fork and 90% of the time it seems to be...

If you reset your pistons, pad retract is always relative to the braking surface so you have the same pad clearance regardless of rotor thickness. Increasing rotor thickness will only impact the clearance/dead stroke if you don’t reset the pistons, but over time as your pads wear it will work its way to the same spot.
Yeah from a conservation of energy standpoint, if you are absorbing the same amount of kinetic energy through damping then heat generated would be the same but the larger oil volume would be advantageous. If running a tune that's more suitable for lower shaft speeds I can see too much heat being a thing.
I spent a lot of time on the Enduro and had it set up with an Ohlins coil shock. It worked really well. I then figured I'd throw an Ohlins on my Crestline DH bike. It didn't go so well. The shock seems to have a fairly stiff off the shelf tune. With the Enduro being a higher leverage bike...
