Just some food for thought, even though I largely agree with you. (or wait, robots don't eat food, and certainly don't need any sort of sustenance for thought. Hmmmm....) 600 grams of rotating weight does suck for normal trail riding. No two ways about ... more »

Maybe that wasn't directed at me. But for the love of God we need to start differentiating between a piece of foam floating in your system (Huck Norris) and a real insert system (Flat Tire Defender, Cushcore) that also changes how the tire rides Nothing ... more »

I have. Honestly, when running one of the burlier inserts and real tires, I am not having any problems with what you are describing. Maybe I need to smash harder or test longer, but on two sets of wheels I am yet to ping/pinch a tire. This, riding somewhere ... more »

"Carbon rims are probably less elastic than aluminum and absorb less force" Not so sure I agree with the latter part of this statement, as its a bit too general for my liking. I have seen some carbon wheels that seem infinitely more durable than their

...inserts basically fix this problem entirely.

Used them with both DD and EXO casing. Have not used them with DH casing. I could run my pressure as low as 18-19psi and still not get the tire to roll off the rim. To me that's amazing. Side note, I didn't actually run tire pressure that low, but it ... more »

Really good post and a cool way to think about the evolution of an otherwise overlooked part of the bicycle system. Spomer said it awhile ago, but the number of races over the years (and overal championships) decided by losing air out of a tire is far ... more »

Cuts deep.

Reply to Coil Shock + Trail Bike 10/17/2017 1:58 PM

It absolutely would work fine. The biggest problem with coil is getting your spring rate right. When the leverage rate is high, it can be extra hard to find the right spring rate IMO and no calculator is all that awesome in my experience. Thus it can ... more »

Reply to Coil Shock + Trail Bike 10/17/2017 1:36 PM

That's a tough one in some ways, only because the leverage ratio is very high, especially off the top. Personally, I think you'd be most well suited to a Float X2 with no tokens as its highly adjustable (no spring weight monkeying around), will be very ... more »

Reply to Quarq Shockwiz... 10/17/2017 8:05 AM

Having used it myself I can say they are good, but not great. A good shop should be able to get your suspension setup nearly as well as the Quarq, with the big advantage to the Quarq being it'll get you to a baseline that is close to "right" without ... more »

Awesome. Taylor made interview!

As some have touched on, an air shock allows the damping of the shock to run cooler as yes, the air acts as a heat sink. However, the air will heat up (obviously) which has its own negative effects. Pick your poison, I suppose. Point is, the idea that ... more »

Reply to Coil Shock + Trail Bike 10/11/2017 2:13 PM

Just wanted to point out two things. First, what you say isn't universally true. As we've pointed out, coils do not work on all frames across the board. Second, a certain engineer has told me air actually can run cooler over long runs, this is especially ... more »

Reply to Coil Shock + Trail Bike 10/11/2017 7:45 AM

I bet RCS would make you a spring. Or if you google around, there are plenty of options abroad. Business opportunity anyone?

Reply to Coil Shock + Trail Bike 10/11/2017 7:30 AM

All good points. FWIW, I don't suggest anyone ditch their modern air shock for a DHX. It was good for its time, but that time is behind us. Air really is going to be the ticket for most riders. Most riders ditch their air shock for a coil before they ... more »

Reply to Coil Shock + Trail Bike 10/10/2017 1:52 PM

LOL It'd probably feel a bit more sporty but a hair more harsh, though I am really generalizing. You see a lot of pros going back and forth these days depending on if they want max progressiveness or a bit more linear-ness. Both have their place. Good ... more »

Yeah, you most likely need to go up in spring weight. Mojo's calc suggests you need to be on a 450 pound spring! LOL. Maybe give Yeti a buzz, but I'd guess a 400 would help! http://www.mojo-store.co.uk/PBCPPlayer.asp?ID=1737817
