Comment from another site: "I wonder if the real reason that Sinyard's back is that he's not getting enough law suit action to feel good about himself."

looks like frameworks already have a prototype for 32" to 29" conversion main frame in testing.

Clutch on the Eagle 90 has me intrigued plus the UDH. Traditional hangers bend so easily. Thanks for the tip. My two cents. Marginal gains are for professionals. Mere mortals benefit from gym, good diet, sleep, and riding your bike more not drivetrains that have batteries and cost a month of rent.

New SRAM stuff is prohibitively expensive. Still buy and use GX Eagle. Why would I need anything else? I’m a gravity rider…my derailleur goes through hell. The last thing I want is to put a $600 derailleur on my bike. Upgrades to shifting? It’s a drivetrain…I click the shifter and the chain changes gear. What is there to upgrade?

I would say that no, it’s not worth it even if an STFU masks most of the noise. I had an STFU on my insanely chain-slap happy bike and one of the loops came off only after a couple rides, flopped into the spokes and got destroyed. Gravity MTB is not really a place where marginal gains make sense, I think the real performance gains comes from rider confidence. The sound of silence is bliss because you’re not riding and constantly trying to asses if that clang indicates that something is about to snap in half, or if it’s just...

Enough. Tell me about the next gen Optic or Evil Following. Anyone have any info?

I think Shimano is missing the point- noise is the biggest issue by far. If my bike is loud, it's bad. I don't care if the suspension is actually working 1% better.

It’s weird - sram can release an ecosystem of groups with proprietary cassettes, derailleurs, chains, rings, that have stratospheric prices and persistent issues (speed, shift calibration limitations, QC issues, cassettes that need to be installed multiple times to settle, battery pins corroding etc etc), plus compromises they try and correct release to release. Maybe that’s ok, it’s up to the rider. At the same time, Shimano releases a new di2 ecosystem that uses their existing(and awesome) cassettes, chains, rings, has the industry leading shifter for ergonomics. A sealed battery compartment, but its perceived to be noisy on some bikes, but...

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.

hummm, if you're talking major MTB companies - I'm hoping this doesn't happen during my lifetime.

How is GoPro not related when I'm watching winning world cup race runs week in and week out on the GoPro Bike YouTube Channel? (Daks helmet sponsor too) On YouTube GoPro Bike has 91k subs vs GoPro Snow at 152k. I honestly thought the gulf of bike to snow would be much larger. Seems like bikes are a huge segment of the market for GoPro (and it's slowly slipping to Insta360 and DJI) I bet a fair amount of people in here have owned a GoPro and basically only used it on their bike. Highly relevant.

It all depends on the bike, tbh. I've ridden all the new Di2 stuff on a ton of different bikes, and I've found that chain sizing really matters. I've tested T-Type and the new Di2 back-to-back on the same bikes, and while SRAM does do a slightly better job of keeping the spazzing to a minimum, it's certainly not perfect. The dual-spring on Shimano takes about 5-6 lbs of force to break free when in the smallest cog on the cassette, and the SRAM T-Type clutch takes about 7.5-8 lbs to break free no matter what cog. The major difference...

I have a lot of time for the approach Shimano take to product development. A lot of the new stuff from every brand is not necessarily better than what came before, definitely different, but with compromises as well as advantages. Shimano just take a little longer to decide if the advance is worth the trade off. The great thing is we have a lot of choice of quality products from a number of brands, so no great loss if the Shimano offering doesn't work for you.

A new v10 isn’t comming out next month lol

Blasting up fireroads at 20mph is SO sick. So rad.

Now that is cool. RC servos are pretty quick for their intended applications. This is a way better idea than wireless brakes.

My Italian is a little rusty, but it seems this was made using a servo from the RC world, connected to some kind of stroke measuring device on the brake lever blade. The idea being to change the compression settings of the shock under different types of braking events.

I'd wager no, just because all the new stuff moved away from it, and that attachment to the cage looks the same as the dual spring jawn.
