Almost certain that Troy probably had the left hand pod to override to either trail or lock on the suspension for the opening sprint and then turned it back to auto (which defaults to open) as soon as the fire road ended. 

Isn't this a similar theory to what's on Bruni's bike?

Shimano has been killing SRAM on the low end market. 5,6 and 7 series Shimano is so much better than NX and SX.

To a 1000% sure, there's nothing funny going on that would prevent running a "gx" mechanical transmission shifter and derailleur with an "XO1" level transmission cassette and chain?  

Assume the "gx" mechanical transmission derailleur is going to have a replaceable cage like the electronic ones?

Also assume the pull ratio will still be 1:1.  Would it be possible to keep an XO1 shifter and just replace a tired X01 derailleur when my current X01 cassette and chain wear out.

Don't mean to turn this into a personal bike consultation. Think a lot of people like me who have never seriously looked at electronic shifting are going to have these questions.

"Regular" flight attendant, you can set the controls to either cycle between locked and open. Or you can have the suspension cycle between lock>pedal>open. (On XC Bikes it locks front+rear, on trail/enduro bikes I believe it can only lock the rear)

You can most likely not lock the DH rear shock, so they probably have it set to a few different compression modes, probably 2 or 3 modes. And they just toggle up or down, or one button cycles the compression modes, and the other always defaults to open. Might be "a lot" to keep track of during a run otherwise. 


I believe the Öhlins stuff does the same, but it has 3 separate buttons. So probably Firm, medium, open.

I think the schtick since Eagle has been full cooperability of parts within the ecosystem and pretty sure it would still work within the Transmission ecosystem. It's not advertised, but I think there were already mix and match builds.

As for mixing and matching, if and when a mechanical version comes out, I guess it would work with  XX wear parts as long as the cassette stays the same between mechanical and AXS models (Eagle was the same, don't see a reason for change). As for the shifter, I'm FAIRLY certain something will change just enough for it to no be compatible. There's a big deal about the way the shifting is done with Transmission but as has been deducted, it's just some delays in when multiple shifts happen - it's just slow. This means you're not pulling the chain across multiple chainrings of the cassette at the same time, minimizing the chance for a dropped chain. I'm running a Garbaruk cassette on an Eagle setup and pulling multiple gears can make the chain go haywire, you really have to shift the gears one by one. There's an eBike Eagle shifter that is a single click and I'd expect the mechanical version of Transmission to have the same solution to ensure slower shifting across multiple gears. You could mandate the use of a single click Eagle shifter, but how to be sure? By making it incompatible.

I hope I'm wrong.

I don't see why that wouldn't work. I didn't get along with the shifter pod ergonomics of my electronic XO transmission so I replaced the shifter and derailleur with standard cable operated XO and it works fine. XO transmission cranks, chain and cassette with mechanical XO shifter and derailleur.

You mean X01 shifter and derailleur? As long as gear spacing is the same, there's not much reason for it to not work. But the question was about using XO Transmission parts with GX Transmission mechanical (supposed) parts.

a) the question was about the shifter.
b) 2nd chainring being of different size would be a non issue if an Eagle derailleur was to be used (but it is not the point of the question). Garbaruk's cassette works without a single issue.

Eagle: 52-42-36-32 (notice the 52-42 step)
Transmission: 52-44-38-32 (notice the 38-32 step)
Garbaruk: 52-44-37-32 (smooth transitions all the way down to the 32t ring)
The rest of the cassettes is the same ratio wise.

But yeah, the point is moot because the original question was about using an Eagle shifter with a Transmission derailleur.

Speaking of @dancingwithmyself , what do you mean by tired X01 derailleur? In my experience they are basically bombproof. My old one that I used for 4,5 years is still in use after I sold it to a friend and still shifts perfectly.

I think it was posted upthread a while back that the mechanical T-Type shifter will be one-click (corroborated on the Geek Warning podcast) to work smoothly w/ existing shift ramps and NW cogs on the T-Type cassette.

BUT: T-Type XPLOR apparently doesn't have this limitation so SRAM could conceivably bring that to mechanical....

The Trek has 650b front and back for size small. Does it still have a 29er fork? Is it worth even making 650b forks anymore? I get that some people prefer the 650b front wheel esp. in the smaller sizes, but the geometry changes between a 29er fork and 650b fork with a 650b wheel is pretty trivial, esp. for small sizes where the frame is designed to incorporate it

I know I'm late to this party, but the difference between a 650b front wheel and a 29" front wheel is enormous in terms of stack height. The same head tube length will be 40 mm lower on a 650b front wheel and 650b specific fork. Especially in a world where manufacturers are already running teeny tiny head tubes (90mm!!) on some size small bikes to get that stack down for small riders, a 650b front wheel makes a big difference in getting small bike geometry and extra large bike geometry into the same ballpark of body position and handling.

Best two ways to get your mechanical Eagle shifting messed up is to smack the derailleur on something or to try to dump 3 gears into the base of a short punchy climb at pace. I absolutely can not ride Eagle like the old 10 and 11 speed stuff from either SRAM or Shimano. One gear at a time as all that works. Even on a brand new setup.

To answer your question, tired XO1 meaning pulleys could probably do with replacing, cage been bent back to straight-ish a time or two, and probably a little less tension in the spring.  I agree that X01 stuff lasts a really long time.

I don't want to derail (I'm here all week!) this thread into a SRAM drivetrain discussion. Games that can be played with mechanical T-type worthy of a seperate thread when it truly drops and we have full and official info.  Think I got my high-level questions answered. 

One more new-stuff category question.  NSB or Wheels Mfg hanger and a DAG solved good mechanical shifting a long time ago.  With T-type mechanical, I'd really be after even more cassette durability for a lightweight ebike or  avoiding the awful 42-52 jump on my enduro bike (I run a 10-50 on the ebike and trail bike).  

Am I right that for riders like the people reading this, those are the two value propositions of mechanical T-Type?

Just to give  Quick response to those wondering about how trek plans to sell these top level bikes at the advertised price. As someone who works at a shop that sells Trek bikes. If you like you can go through online tutorials program called TrekU and once you have completed enough modules, you are awarded employee pricing where you are able to buy bikes at 30% off cost.

I assure you these top level bikes are built to bait newer staff of trek dealers to buy what looks to be an incredible deal. They have no intentions to sell these to normal folk and I have yet to see them sell one to a normal consumer. My guess is trek works sick deals with parts suppliers buy agreeing to build top spec bikes with top spec build kits. And then they just end up selling that at discounted rates to shop employees while keeping the buying power with components companies.

Before we grab pitch forks... Fox, Easton, Shimano, SRAM, abus, and many others have similiar programs. I take advantage of all of them. I'll drink the koolaid and ride that bling baby!  

Okay back to tech rumours.... Gosh.

pretty much how it works, This is how alot of high end bikes get out and helps the workers get these bikes which in turn advertises them.
Alot of shops will also initially absorb these bikes and the employee's will Pay the shop(employer) back for them.(atleast that was the perk of Many of the Jobs i looked at to offset the low pay)

Regarding the awful jump, I mentioned this in one of the posts in this derail, Transmission still has an awful jump, it just moved from 52-42 to the 38-32 ratio (previously 32-36). That's why I went with the Garbaruk cassette because it has a 52-44-37-32 ratio which is the smoothest possible layout given the bottom end and a 52T ring.

long time reader first time poster here..

friends of mine are developing an vacuum bleeder for shocks and fork dampers to fully service your suspension at home, without the need of messy handbleeding.

I just got the chance to try the machine myself and it works pretty straight forward. I thought i spread the word in here because i think this is a pretty cool innovation in the mtb tech for home mechanics/ race day applications etc.

That looks real nice.

Any idea on price... If its designed with at home servicing in mind, then hopefully it won't be as expensive as the "pro" ones.

This could be awesome for suspension techs that come out to more local race weekends and what not. If you have. Very cool.

Santa Cruz Bullit 4 rumours.

Bike would be revealed early April, Gloss Black & Matte Teal Sparkle colors.

New SRAM Eagle 70 & 90 drivetrains (mechanical) on lower end builds.

SC are now showing pictures of an unknown color (looks like Gloss Black) on their Vala page.

Santa Cruz are tagging bike models in the name of the photos on their website and they tagged in the Bullit (VA-BU as in Vala-Bullit) on all of the pictures below.

Also assume the pull ratio will still be 1:1.  Would it be possible to keep an XO1 shifter and just replace a tired X01 derailleur when my current X01 cassette and chain wear out.

Don't mean to turn this into a personal bike consultation. Think a lot of people like me who have never seriously looked at electronic shifting are going to have these questions.

Dunno about any of that. I just know it's gonna be offered in those build levels. Would assume you could run an XO/XX cassette on it though if the spacing is the same. SRAM will likely have something against it saying it "doesn't completely match up the shift opportunities resulting in degraded performance" or something to try and sell you on the AXS stuff.

friends of mine are developing an vacuum bleeder for shocks and fork dampers to fully service your suspension at home, without the need of messy handbleeding.

I just got the chance to try the machine myself and it works pretty straight forward. I thought i spread the word in here because i think this is a pretty cool innovation in the mtb tech for home mechanics/ race day applications etc.

Yes, please! Sent this to a buddy who is trying to get suspension service availability in his shop. Any idea what pricing would be? You have a working model yet?

Santa Cruz Bullit 4 rumours.

Bike would be revealed early April, Gloss Black & Matte Teal Sparkle colors.

New SRAM Eagle 70 & 90 drivetrains (mechanical) on lower end builds.

SC are now showing pictures of an unknown color (looks like Gloss Black) on their Vala page.

Santa Cruz are tagging bike models in the name of the photos on their website and they tagged in the Bullit (VA-BU as in Vala-Bullit) on all of the pictures below.

Long stroke the shock to 65mm and get 160mm, slap a 170mm fork on. Different paint, minimal investment???

Hey, give SC some credit. They might even put in the effort to create some altered linkages — maybe even a new rear triangle if they’re especially motivated.

Wow this is awesome. 

 

One thing I've always wondered, why don't we use vacuum pumps for brake bleeds? You can just fill the tank with mineral or dot and attach it onto the master cylinder and away you go. The commercial vacuum bleeder fox recommends has 4 tanks for different fluids already

I am sure it would have to do with the master cylinder bladder. Would be cool though.

Hope used to make a pressured bleed system, you fitted a special top cap to the lever and pressurised a bottle of fluid with the air in your tyre which forced the fluid through the system

Yeah bleeding brakes with a vacuum pump is a great idea....mineral oil at least would be pretty much plug and play and I honestly don't know why it hasn't taken off. It definitely works and would cut down brake repair time a massive amount!

 

Actually I know why it hasn't - shops are usually pretty averse to spending money on equipment....they would much rather fumble around with some hacked together system they made or pay way too much money for a 50 cent syringe and some brass fittings that only fits one model of one brand of brake

Tektro makes one. I haven't actually seen it in person but it's on their website. I haven't found a way to order one yet.
