The front brake/rear brake thing really comes down to terrain and riding style, but mostly terrain. There are trails where it's easier for me to accidentally make my rear tire skid, and other trails where it's easier for me to accidentally make my front tire skid. If grip is good on a trail, my weight is typically going to shift forward when I brake, loading the front tire and creating grip there while unloading the rear. On trails like that my front brake is going to do most of the work slowing me down, which is what we would typically...

It was promising- less chainslap in general but on very large impacts chainslap was worse as you'd pull the derailleur into the weaker spring zone. Shifting was actually improved- less tension on the chain going into big cogs. Think the best would be a massive torsion spring to add tension everywhere and then use the cam over spring to mostly subtract tension going into the large cogs. I believe that is the limiter on cage tension. Once you have too much- the derailleur doesn't like shifting into the big easy cogs. I filed paperwork to patent, begged, pleaded, told everyone...

Parallel cam-over spring so it adds chain tension in the small cogs and subtracts it in the large cogs. Edit: pulled the pics- don't want to make trouble.

He needs a proportional water bottle!

I've got a minor brake annoyance that I'd like help diagnosing. I'm running Mavens on both my ebike and regular bike, both with TRP S05e 203mm rotors. The regular bike I run the SRAM organic pads, and on the ebike I run SRAM sintered. I've noticed that on warm, dusty rides (read: almost every ride here), the front sintered brake on the ebike is noisy at the start of a run. If I aggressively brake hard (drag front brake) it will go away for a bit, but then come back pretty quickly. The sintered rear doesn't really do it, or...

Not going to lie, you had me at googly eyes.

I need to get some bigger ones and maybe 3d print a mouth that goes on the bearing to make it look like its screaming I do honestly do work, I pormise

The machine is basically a motor that turns a shaft, which is turned in to linear up and down motion. The software runs the machine faster and faster, and measures how much force the damper is producing at every point and speed in the stroke. My machine is a CTW "rotary" type dyno with 2 HP and one of the more basic, lower power machines on the market (I think about $15,000 USD today). CTW was born out of a company called Roehrig who pioneered workshop damper testing in the early 90's - many of the older racecar and motorcycle...

Dude, dude, dude... hear me out: I agree that you'd ideally want to have cage spring forces that are lower in the big cogs for easier shifts while climbing and higher cage spring forces in the smaller cogs for greater chain retention and chain calming during descents, and yes the current arrangement on the new dual-spring Shimano RD's is kind of the opposite of that. You know what could be done by Shimano to reverse the derailleur cage spring force problem? You know what they could do? You know what? RAPID RISE IS BACK BABY!!!!! LOW NORMAL THIS IS YOUR...

This video was cool because it showed how separate the rear shock and tire are from each other, despite working in series. These are the most sophisticated full suspension bikes on the planet, and it's still a shitshow back there, with everything moving at a different time in the sequence and at a different speed. I need to watch this video ten more times to figure out the exact sequence of what's moving in what order, how fast, and how far.

The new hanger/ Dura Ace group was discussed on the Geek Warning podcast recently and they said the new hanger was to allow the smallest cog to sit further outboard (pushing into the space SRAMs "sandwich" design clamps the dropout) because the 13-speed cassette uses the same hub driver and chain as 12-speed (so cog spacing is also the same as 12sp).

To really level the playing field any top level racing should be limited to 20" wheels.

I won't sugarcoat it, He single handedly ruined MTBR suspension forum. There were so many knowledgable industry insiders, inventors, owners and passionate puzzlers on that forum and according to him they were all wrong, non-sensical ranting and bickering meant most of those incredible posters left the forum and didn't contribute anymore. Don't let history repeat itself is all I'm saying, this forum is the exact same, nerds, industry insiders and company owners all stoked on bikes. Let's keep it that way!

Wow, that looked like a great race to watch. Thanks UCI, for paywalling it--ya suck! Top four men within 1.5 second, all under 22 years old. Jonty coming up next year. The sport is NOT slowing down.

100% Honestly, we have a really good thing going here. We have amazing contributions from people doing amazing work across all aspects of mountain biking. We've had multiple owners of companies, other engineers, product testers and designers give incredible feedback on a wide variety of topics. Giving their time and their knowledge in constructive ways to help foster a level of bike nerd and discussion that you just don't get elsewhere, and they do that because vital isn't a cesspool of negativity and combative complaining. I'm sure everyone working on the hard part of designing, engineering, building, testing, is doing...

I wasn't sure where everything was coming from but a bit of Googling shows there was a suspension guru with the handle Dougal on mtbr that got banned for... Let's say unkind posts. I think @DServy assumes @Dougal - SC is the same person behind the mote or less the same handle and doesn't want Vital MTB to turn to the shitshow that was MTBR before the ban. Or something along those lines?

Dear Dougal, I know your favorite past time is to shit on the hard engineering work of people and then yell at them when they try to engage you in good faith arguments. I get that you are also trying to be helpful, and probably mean less malice than it comes across over the internet because, frankly, the internet is a shithole of everyone yelling at each other. But Vital has been a space that seems to have remained a refuge of reasonability despite everything else falling to click and rage bate. I am glad Vital is not the pinkbike...

Gwin did not “qualify” via the criteria. 1.Dak and Dylan qualified with last year’s worlds results. 2. Luca qualified with his wc win 3. Pinky qualified with his wc podium Evan, Richie, and Aaron all “qualified” Via a top 20 wc result this season. However USA can only send 6 racers. Richie and Evan got lower results in Korea and Aaron never bested those results in the wcs he entered. It’s just the rulebook. Nobody made a judgement call. As much as I’d like to see Aaron in world champs he didn’t earn it over the people who did. I...

Ok you dingleberries. Rather than debating the merit of which way to mullet your rotors, why not just run 220 front and back?
