Commencal quietly dropped the Tempo "V2" with the only revision being they got rid of the headset cable routing. (praise be!)

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.

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...

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...

Advent MX is so good. I'm running it on the ebike but would happily run it on my park or trail bike too. MicroShift derailleurs are much more impact resistant than Shimano in my experience. All I want from a derailleur is for it to be cheap, overbuilt, and never in my spokes. Their customer service is great too. I broke a tooth on the cassette early on and they shipped out a new one no questions asked. Imagine going through that with Shimano.

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).

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.
