Primoz Added a comment about feature Sneak Peek: First Glimpse of SRAM's X01 Drivetrain

I've said a couple of times, that the spread of an 11t cassette or a 1x11 setup is kinda small copared to a 2x10. A 44t cassette would definetly help (together with a 9t cog, all of that then neatly packaed in a 10 mm pitch system with an 11-~50 cassette in the same dimensions, diameter wise). Though based on my calculations, i could just barely make it with a 44-10 casette and a 30t in front, that would quite closely match my current 22-32 and 32-11 cassette setup.

9t doesn't work because of the polygon effect. Read about it in Bikeradar's presentation of the XX1, where it was told the protos used a 9t cog from the Shimano commuter grouppo. Unless Shimano decided touse a 10 mm pitch chain for their 1x11 group, then they could use an 11t in a 1/2" 9T cog diameter. EDIT: damn you...

Doesn't a lifetime warranty mean until the product is EOL? o.O If it's not, what lifetime? A persons? The average human liftime? The lifetime of a tortoise (up to 150 years)?

I'm familiar with the way F1 works. And it's not completely analogous to the MTB world (my racedriver/testdriver analogy is still correct since it in no way limits itself to F1), since there are ~5 F1 cars made per season, the testing is COMPLETELY limited and you really need to be in top notch fitness to get anything, not just the most out of the car. Still, teams (Ferrari) used to have 2, maybe even 3 drivers on the team that were used specifically for test duties. In the case of Ferrari, they were far from top notch drivers (Luca...

Can't reply to your comment, the thread can't go as deep. When you're the engineer tasked with modifying something, if you can feel what's wrong with the product you have THE EASIEST job to modify it. WHen someone else has to tell you what they feel, you instantly get a place for errors or misunderstandings. Yes, data acquisition is important and gives a totaly different picture. Yes, testing to destruction helps. But you can have a dyno test something to destruction all the while not endangering ANY rider, a pro or not a pro. I can see you don't get...

As long as you have an IFP, you have pressure behind it, since that takes care of the rebound shaft, that takes up space inside the damper body - the oil that was there has to go somewhere, it goes into the piggy and oushes the IFP back. If you raise the pressure, the compression characteristics of te shock ramp up a bit. The negative spring is behind the piston inside the damper body, helping it to start to move. I don't exactly get how it works, i'd need to see some better pics, schematics or plans, but it's prolly...

Joke or not, it's not the marketing you'd expect from a company the size of Sram. And speak for yourself, as i said, it's not the speed, it's the feel. No mater how safe a line you take, you still have a LOT of travel in the suspension. You blow through it. Ergo the shaft speeds are high and you do need damping. Sure, the compression dial will be way out compared to a pro, but the fitness level of us is also A LOT lower than the fitness level of a pro. And that's the whole point. You say...

It's not the speed that makes you need it. It's the feel. Here's a car analogy. A good racecar driver (a fast racer) ins't always a good test driver. A good test driver isn't always a good racer. You don't need to be a good (categorized) racer, to be able to set up this shock and use it to it's full potential. It's not given that a good racer will be able to set this shock up properly, to make the best of it either.
