Thanks Dave! A few other advantages of the Ohlins TTX technology is no worry about cavitation and no need to pressure balance. Also, re-valving is much easier than in a single tube shock.

came to say similar- I am curious since there is still a pressurized chamber, how different the pressures are?
@theohlinsguy46492 ай бұрын
@@bradymoritz It is interesting. With a single tube shock when the velocity of the piston gets high the pressure differential across the piston gets enough you will get cavitation which not only ruins damping but if it happens enough will also pit and ruing the piston. The only way to ensure that you are not getting cavitation is to have enough pressure in the shock to control the pressure drop across the piston. With TTX technology there is no danger of cavitation because the oil flows through stationary valves. You need some gas pressure but not to stop cavitation.

The biggest problem we find with this design.....and it is a big one...Is that the shaft piston area is so so large compared to that of the valve port area. This results in a lot of harshness due to the fact that oil wont compress and it is rapidly trying to accelerate through the very tiny ports. As you would be aware, damping is velocity sensitive and the force rapidly rises on square edge bumps making the ride super uncomfortable. The SBK TTX has much larger pistons compared to that of the consumer model in order to overcome deflection off bumps. Sadly anyone that has purchased a TTX equipped OEM bike may not agree with your adoration of this concept due to the lack of attention paid to basic mathmatics by Ohlins. Most track bikes wont see wheel speeds over 600mm per second but this is easily exceeded on the road.

Good one Terry 👍 In that case what shock absorber would you recommend in high end quality like this Ohlins for the road application only ( not racing).

Everything I’ve read about the TTX being used on Triumphs reflects this. Really disappointing but I’m happy because I have a Penske Double Clicker. Easy to work on for an average mechanic and works great on track or road.

Hi Dave, does the cbr tripple-r (non sp) have completely separate rebound and compression. I couldn't find much trustworthy info anywhere. What does ballance free rear cusion even mean? I suspect showa bpf isn't separated... Thanks in advance!!

Since a twin tube is pressing oil against the valve during compression, the nitro charge pressure can be much lower, correct? I'm curious what the nitro pressure differences are (the single tube has to run higher pressure to prevent cavitation...)
@obsession_engineeringАй бұрын
Normally 5 bar on a twin tube, vs 10-12 for a single tube

Kind of funny in the bike world you have Monotubes and they sell you twin tubes as a sporting upgrade while on the car world twin tubes are standard and they try to sell you mono tubes as an upgrade
@theohlinsguy46493 жыл бұрын
The twin tube shock you are talking about is very different from the TTX technology. Most "twin tube" shocks have a foot valve for compression and are emulsion (pressurized gas mixed with the oil) type shocks. Very old technology.

For me I sourced a used ohlins off of a wrecked bike with 2k miles for 350$. I sent it to ohlins USA for inspection and to set it up for my weight and style. All and all it was around 600$ installed and yes I believe it is worth it.
