Video: A Mid-Winter Downhill Rebuild
@henryquinney: Agreed, particularly on the small stuff on bikes where the torque is so low, new parts vs used etc can can cause a huge variation in bolt tension achieved, which is the objective, after all. I reckon they are more or less o.k for cars and then by the time you get up to the big heavy engineering stuff I deal with you need ultrasonic measurement of the change in length or some other direct measurement of the actual bolt tension. But then I do understand that some bike owners will work on their bikes and have absolutely no "feel" for when to stop tightening, so maybe they will reduce those sort of issues.

Opinion: Your Next Bike Will Be Steeper
Is it just me that can't understand how anyone can actually ride downhill while putting substantial weight on the bar? I have seen the assertion that a lower stack puts more weight on the bars many times but I really only carry my weight on my feet, with only enough on my hands to feel a little pressure and know I'm not hanging off the back. So lowering stack only seems to me to make the bars harder to reach while not affecting my front to rear balance at all. Maybe I'm weak, or old and inflexible, or maybe I just learnt on old and super short bikes but it's hard to understand how people can actually lean on the bar and still stay on the bike.

ARC8's Prototype Downhill Bike Uses a Sliding Shock Mount
Short, exposed bushings not in line with the centreline of the shock feels to me like a recipe for friction and therefore uncontrolled extra damping. I absolutley see benefits of some aspects of this but simple sliders don't seem like a good idea.

Review: Berd’s Hawk 30 Wheels Use String Spokes for Impressive Compliance
@BarryWalstead: At least a couple of incorrect facts there (the modulus / stretch and the creep) but I did have an interesting few minutes looking up the physical properties of Dyneema, so thanks for that.

Field Test Review: 2024 Trek Slash - Rides Like a Session
@KickFlipABike: The ability to eliminate chain growth isn't anything to do with the size of the idlers, just where the idlers hold the chain. Imagine the top and bottom length of the chain weren't wrapped round a chain ring but simply pinned to the center of the rear suspension pivot. As the suspension move, the whole rear wheel and chain assembly will move together and there will be no change in chain length on top or bottom. The closer the upper and lower idlers get the chain to being on the pivot, before guiding the chain to the chainring (or off it), the closer you will be to that situation and the mech will not move as the suspension compresses. In practice, a lower idler that holds the chain on a line drawn from the lower mech jockey wheel to the suspension pivot and pretty close to the chainring will get 95% of the effect, and that's what they are aiming for here, and if you have a look at videos of the suspension being cycled through it's travel in reviews when the bike was released, it works, the mech arm doesn't move significantly. Compare with a high pivot bike without a lower idler and you'll see the mech arm move a lot more. That all said, a much bigger idler would run much smoother, and keeping it perfectly aligned and with a small stop over the top of the chain to keep it from bouncing off the idler would make it all more robust.

Field Test Review: 2024 Trek Slash - Rides Like a Session
The main benefit of the lower pulley is not for chain retention in this case, it's there to stop the lower chain run growing when the suspension compresses so that the mech arm doesn't need to move when the suspension compresses. Essentially trying to give you the "no chain" suspension feel by removing the influence that the clutch and spring on the rear mech has on the suspension.

The Good, The Bad, and The Ugly: Pinkbike Editors' Cockpit Setups
@qbensis: if the bar has any substantial amount of rise, the grips will move forward and back so much as the roll is adjusted to suit comfort preferences that I don't think there is any predictable connection between bar rise and reach. At least stem spacers will only affect it in a predictable way! Plus, as this article and comment section is revealing, having the primary rise of the bar actually vertical is probably not in actual fact the intended design, nor the most common way to mount them.

The Good, The Bad, and The Ugly: Pinkbike Editors' Cockpit Setups
Not at all, lots of people do this. I used to and liked it in some situations but found that over a long ride the upsweep on the grips made me ride with my shoulders shrugged and killed my back so I rolled them back quite a bit and now prefer that. There's no one solution that suits everyone.

Interview: Downhill Wheel Tech with DT Swiss
@rocky-x: No, that's a pretty standard phrase, at least in the UK, just means to try something and see how you like it.

A typo of "a brand new track", unless I am greatly mistaken. But I see that they fixed it anyway.
