from article "Gear ratios are smoother too with the 52t largest cog now stepping down to 44t and 38t gears. " all the rest are the same as old cassette.

thanks for sharing your experience, I plan on going for a runt myself. I worked at Fox suspension for a few years and helped DSD a few times, acquire some Fox parts. I should have pulled the trigger back then, but it looks like BTI sells them so I plan on snagging one when back in stock. What made me decide to get a runt, was actually trying a Helm. You can bleed the air off and effectively make it a dual rate spring, which greatly improved the feel. So adding that functionality to a 36 should be sweet

Everyone here should read this if you have not yet, pretty sure it's available in e-form. It will answer many of the questions posed here, and cut through the confusion. You can then ask the important questions like why is RockShox so enamored with digressive compression and rebound stacks? In regards to mid valves on fork dampers, many of them can have a rather large compression effect that can produce spiking at higher velocities and add to a harsh feeling. To test this on yours; close the (low speed) rebound adjuster all the way, which closes the bleed around the...

MTB's have had it for years! The KYB SSS is just a marketing term for Speed Sensitive System. It's not really an actual thing, but rather Yamaha adopting an aggressive damper tune from their racing program and offering it to the masses as the standard production spec. Generally speaking, the media guys who test bikes are amateur racers so production MX suspension was always a bit on the soft side. Yamaha goes aggressive with the production-spec and voila! Test riders around the globe rejoice and report that it's the best suspension system out there!

Rear shocks do not have Mid-Valves. Let's take a 170mm travel trail bike: Front wheel travel is 170mm, fork travel is 170mm. Front Fork Wheel Velocity Range is 0-9m/sec, fork velocity is 0-9m/sec Rear wheel travel is 170mm, shock travel is 65mm. Rear wheel velocity is 0-7m/sec, shock velocity is 0-2.7m/sec This is due to the fact that rear shocks are driven by a linkage or pivot system so the motion is not directly 1:1 like a front fork. Because forks are dealing with a larger travel and velocity range, mid-valves were introduced as another tuning element to reduce compromise...

HBO and Position Sensitive damping have been around since the early 2000's. The original FOX 36 released in 2005 had HBO... we've had SPV, Boost Valve, Curnutt, etc which have all been position-sensitive systems. HBO is still useful, but position sensitive less so now that most bikes have a pretty good rising rate linkage rate. -Darren

I believe that mid valves are common in rear shock? Especially RockShocks with piggiback all use mid valve, they have 2 compression stack, one on the piston and a base valve near piggyback. I think that Bomber CR does that as well. Or maybe this is just a naming thing?

I like that hydraulic bottom out is becoming more popular on "mainstream" suspension. The industry seems to be slowly stealing ideas from trophy trucks and other offroad motorsports. Will we see position sensitive damping and mid speed damping control in the next few years?

Just for some clarity: Base Valve(s): These are the fixed valves that displaced fluid moves through. Mid Valve: This is when you are creating compression damping on the backside of the rebound damper piston. This is often just a check valve as creating force on the back side of a rebound piston can get tricky due to how easy it can cavitate. Mid valves are not found in rear shocks. Damper Piston: Is what is attached to the shaft in a rear shock and is in motion. Rear shocks are circulatory therefore you don't have fluid flowing in multiple directions...

LTrumpore yeah duh, I brainfarted. Yes, you're right that cable tension doesn't prevent a derailleur from moving inboard during an impact. Thanks for clarifying that. Regarding the new cassette shift patterns, it seems like they basically did the same thing with the new T-type cassettes that Shimano did with Linkglide. Instead of enabling shifting under load at any point in the cassette (like a Hyperglide+ cassette and chain), the shift will only happen at certain intervals in the cassette where shift gates are located. This means the shift is slightly delayed, but super smooth, which might be why every review...

Isn't the puropse of the breakaway to mimick a traditional derailleur and protect the servo motor gears from being damaged from an impact? A cable operated derailleur (except Shimano's rapid-rise experiment) can already move inboard quite far since it doesn't tension the cable in that direction. You can shift into lager cogs pushing your thumb on the cage without using the shifter if you want to. Without pedaling it'll bind mechanically after about 5mm, but so will an AXS system. It's only going to be a matter of time until this works its way onto all levels of SRAM drivetrains...

?? AXS shifts when you push the button, there's no way for the system to know where the cassette is in its roatation. Previous geration Eagle AXS and Eagle cable systems all use the same cassette.

I think no cable version will exist unless they modify the cassette design due to the fact that it's designed to move the chain at a certain point on the rotation. If a cable version exists, one would essentially be able to shift at any point on the cassette, thus negating the intended design.... I think 🤔

Unusual that the sprocket sizes aren't quoted. Anyway they're 10,12,14,16,18,21,24,28,32,38,44,52, so they're an improvement at least.

DPX2 is a Mono-Tube design. The displaced oil just happens to transfer through the shaft into the reservoir like the older Rock Shox Monarch shocks. This design is to allow ease of air can service. Nothing mysterious is going on.

The SRAM XX SL chain is £160 in the UK. That is a LOT of money for a chain and a lot more than existing 12-speed chains. For £160 I would want a self cleaning/lubricating chain.

When AXS first launched in 2019, the groupset pricing was $1900 for X01 and $2k for XX1. And look, it's a lot of money, no two ways around it. But coming in at $1600 and $2050 with the new stuff, with the way prices have gone up for just about everything over the intervening period is pretty impressive. I'm not in the market, I'm very happy with what I'm currently on (mostly Shimano), and I don't really do upgrades anyway. Buy once cry once, you know? But if I were building up a new bike, this stuff would be hard...

Seen in the video released today by Santa Cruz, perhaps the final design and official color of new V10?
