I ride and race Dh as well as trail riding, I am not a keyboard warrior and ride master, I am current Scottish vets Dh champion and have done my time to make educated comments based on experience. I train hard for racing.

First Ride: Promising New Suspension Design From an Unlikely Source
I accepted a long time ago that my failure to commit tot the front wheel when it really matters and corner hard is the issue. If you are not qualifying for a WC. Just face it..its not the bike its you. Another new solution here to the problem of the pilot :)

Shimano Patent Filing Raises Electric Questions
@Dangerous-Dan: BLE can communicate over significantly longer distances than from the mech to the shifter. I could guess which IC they use for their BLE. Between 2 companies but based on their developmemt time I would be pretty confident who they use. The BLE will have a separate registration for every country they sell in which costs money and conforming to Red will have just cost Shimano a few dollars for a low volume niche part which the consumer will be paying for. As for rechargeable batterie's, there is lots that goes on in the background that consumer's don't realise. I failed 5 supplier who wanted to supply us a battery for a medium volume medical device. Max 1 million units per year currently. As for sealing. It looks like they might have an external battery for capacity, sealing is not an issue and makes the design more simple in some respects as it frees up valuable real estate for the motor and controller which will be a basic motor and drive I would guess.

Shimano Patent Filing Raises Electric Questions
I love the idea that the rear mech is better because it doesnt have a cable, but... there is a cable going to the battery. The benefit of electronic shifting is... mmmm.. there is a battery to worry about, environmental impact of battery and battery disposal, additional supply chain constraints (probably sea freight compared to air freight for no batteries), additional change control, more parts to fail (lower reliability), more expensive... looks like marketing v engineering. (I work in R&D so know the battle all too well).

Shimano Patent Filing Raises Electric Questions
A blocking patent by Shimano... something they have deemed to be beyond a current trade secret. The patent has to be novel and with no prior art available. People like Waki putting out sketches of far out there ideas into the public domain may cause issues for patents in the future as these sketches could be considered prior art.

Throwback Thursday - Gee Atherton's Bonkers 2010 Rampage Wall Ride
@jaame: .... so a single trick of a 360 v a run without a trick from Gee... did you not just argue against your own comment? Look at Gee's run again compared to others and look at how big he went, so smoothly on so many features. The issue is that when you are that smooth, the features where you triple what others are doubling just look plain. Gee also did it, not off a wooden feature (are we not lucky that the wooden era seems to be over, shame it has been replaced with the sandbag and smooth era)

I think Gee was the only rider to land this take off to wall ride. His run was too smooth, was by far the best and most controlled run that year with the biggest air, it was just too smooth so he made the big stuff look small so didn't win.

Carbon vs Aluminum: Separating Environmental Fact From Fiction in the Frame Materials Debate
Great to have an informative article. It's such a big topic and nobody really knows the answer. Not even the material specialists due to lack of information through the entire suppliers chain. Bike frames are probably easier than other products, but it's a big question regularly for design engineer's. Interesting that the tech you read it on... the companies that make the chips inside your device you read it on don't pay enough detail to the where and how for their compound's etc that go into IC's. They use well known companies for chemical break downs for Rohs, Reach etc. Unless of course you are American where you can still used leaded solder which has not been allowed for CE marked products for many years. Its (EIA or Environmnetal Imoact Analysis) a big can of worms and often the source of pain for engineers in medical companies etc, especially these days with new manufacturers popping up all the time, buying legacy fabs from the old big boys who leave arenas due to price pressures.
