Back to bikes. Can anyone identify this tire? It was taken from Loic Brunis POV from Lenzerheide. I dont think its neither a Cannibal nor Butcher nor Hillbilly.

"If your bars aren't at least as high as your seat at full extension, they are probably too low for a trail or enduro bike."

At 6'2 with a 34" inseam I'd need ape hangers to achieve that. Laughing

Try it. I went from a 40 mm stem and a 30 mm rise bar to a 35 mm stem and 55 mm rise bars. A world of difference (in a good way).

I'm only 6'0" but ride a bike with 515 reach paired with a 31mm offset stem and 83mm rise bars with 15 degrees of backsweep. I've also ridden the BMB Raised Reverse stem on my bike. Zero or slightly negative effective offset is great from my experience. 

Also, stack doesn't scale with reach on larger frame, so you need to have higher bars on bigger sizes. If your bars aren't at least as high as your seat at full extension, they are probably too low for a trail or enduro bike. Stack is just as important as reach when discussing bike fit and we really should be measuring these numbers from the handlebars, not the frame.

I love this photo because it highlights how stack is not factored into bike fit. Think about how wildly different the riding position is for these two riders!

I only clued into this phenomenon last year but I wish I had figured this out when I started riding 10 years ago.  It seems crazy at first to add so many stem spacers and to get such high rise bars but it makes a world of difference.  I'm 6'2" with a 32 inseam for reference.  I would say any range +/- 25mm from your seat height will work depending on conditions etc.  My DH bike is slightly above seat height and my enduro bike is slightly below.

Should we move this bar height debate into a separate topic? It's a thing I've started thinking about lately and tried a few things out (as noted above), so would love to discuss it in more detail, but this really isn't the place.

FWIW, I tried a set of DB8s yesterday and a set of Maguras (MT5?) today. I'm starting to think the 'hitting a wall' style of the bite point might be connected to the use of mineral oil?

Looks like Trek are taking more than a bit of 'inspiration' from the Hope HB916...

If someone wants to create a topic, I'd be up for it. I've been looking into the relation between stack and reach and bar height in general a lot lately and would love to hear you guys ideas and theories.

Pretty funny that the Spartan (and Chainsaw), HB916 and now the Slash all use the exact same layout. It should make for an interesting comparison to see how they're tuned differently.

Not world cup, but Norco has something new coming. T-Type, Small shock, look pretty trail to me?
The Sight and Optic are fairly up to date still. Maybe a light E-bike? Revolver?

Sight would have a Piggyback Air Shock and a lyrik/36. The bike in the image has a pike and an inline shock so thinking it's more likely the new optic.

Inline shock, non-high pivot, and the Pike rule out a new Optic for me, as all signs I've heard point to it being even more aggressive with an high- or mid-pivot+idler design. It's a little hard to make out the downtube and DT/BB junction area, but from what I can tell they certainly look pretty chunky, so I'm going with a new Fluid VLT (especially considering that the Fluid was recently overhauled).

Yeah I'm also not convinced this is a new Optic. 

The current one is still super up to date compared to its competitors, even though it got released in 2019. That's because it seems like every short travel 29er that has come out since basically emulated/copied the frame geometry of the Optic. There's simply no need to update it in that regard.

Also there's the matter of the in-line shock. The current Optic was universally praised by media and consumers alike for its category-defying descending capability - thanks in part to the heavily damped semi-custom SuperDeluxe Ultimate DH shock. Would be a weird move to spec the successor to such a bike with less shred-ready components.

I think this might be a carbon version of the very popular Fluid FS that was released last year as an alloy-only model.

 New maxxis pattern spotted on Brendogs instagram. Looks like it bridges a gap between the shorty and assegai maybe? More spaced out and looks taller than assegai.
