DMR Sled suspension analysis

Hello guys! Thank you for sharing my video 😀

Yes, there was no need to created an additional shock linkage. You can achieve a similar result with a traditional 4-bar linkage. Actually, the YT Tues has a similar leverage profile (more progressive at the end), and many other bikes also have the same (even my old Big Hit 2010 have a very similar profile… Tripe Phase System – TPS eheh).

But, brands like to differentiate their products. In this case, having a “MX-link derived from the motocross” sounds cool and it sells! Having a “MX-link with a TPS system” sells even more (although they are just marketing acronyms…).

But overall the bike is quite good, and that’s what matters.

Bye 🙂

my kinematic analysis of Mojo 3

Hi! Sorry for the delay but I don’t come here often… You can reach me through Youtube or something 🙂

You can try the tap and die method or using an external clamp mechanism…. something like this:

Be creative 😀

Bye 🙂

Hi,
Just to share my linkage review about YT Capra 2016 🙂

Hi. Yes you have to put 120 Psi to firmly fit the 26 wheel. Yes the tubular has a tendency to invert. When inflating the tubular firmly hold the tire with your hands to avoid twisting (grab the tire in the opposite part regarding the valve). You can put +170Psi and let the tubular stretch 24hours in the rim. When you mount the MTB tire the tubular has less room to twist. Bye 🙂

alexh wider rims do not completely protect you from burping and denting rims 😉

its an extra weigth of course, but for some people it might be irrelevant. I use heavy duty DH tubes (470 grams each one), so in my case I saved 200g with this system 🙂

Hello from Portugal.

I’m the author of the first video (you know, that pointless stupid wtf video).

I’m not an shock expert, and the video has the value that it has! Probably you can do better and send me.

The drop test in the video was a simulation of a quick small impact. As you can see, in the shock coil, the shock absorvs the energy of the impact, and in the air shock, the shock does NOT absorbs anything (it doesnot move either) which means that the shock is “blind” to small impacts. So it is not a rebound problem because the shock does not compress. The problem is that the air shocks have a stupidly higher pressure in IFP (200-300 psi) and have more friction, which results in a harsh ride. As probably you should know, IFP pressure is needed to pressurize the oil in damping, to avoid hydraulic cavitation, but, more than that will reduce the small bump performance. The reason that conventional air shocks have such an higher IFP pressure is to have some pedal “platform”…But that kills all the bump performance! In my Swinger Coil shock, I’m running IFP at 60 Psi.

You can do this test to a lots of different air shocks, and in most of then, it doesn’t bind the wheel in the ground. Recently I also did this test with an Enduro SL with DHX5 air with minimum pressure (90Psi) in IFP and it also does NOT bind the wheel completely, although, it bounces less than AFR.

As a conclusion of this test, the coil shock has a lower blow-off treshould in such a way that can absorve smaller impacts.

This “stupid wtf pointless” video means that when you are in a fast bumpy downhill singletrack, the wheel keeps in the ground, and you have a much more plush and control ride than with an air shock!

So, I do AM and FR type of riding, and IMO the coil is much much better for everything. Only disadvantage is the weigh ganning. It doesnot suffers from pedal bobing, it is more active in climbing (more traction), and much more plush in downhill.

Good bye from Portugal, and try a coil shock in your AM bike, I think you will like the feeling.

Bye good rides and sorry the english.
