Just to put a word in on direct comparison, I had a bike with Xt8120 and another with Cura4, both with MTX red pads. I found the cura 4 easily more power on tap. So to me something seems weird here. I never used formula pads, but the enduro mag test made it seem a pad upgrade had a major impact on power, that maybe is the case here? The bleed shouldn’t matter unless it feels spongy. I would try doing a full reset bedding process using acetone on the rotor and a bit of sandpaper on both the rotor...

When I did it, I flipped the bike upside down, took the wheel out but replaced the rear axle. I tried to set it up so that the tires were level before I removed the wheel (extended seatpost IIRC). I then hooked a ratchet strap to the rear axle to hold it up, at the starting shock stroke position, then removed the shock. Key is figuring out what your zero stroke is, most frames can extend a bit past that. Then I measured vertically axle to floor in 5mm increments, taking corresponding measurements from the sensor stroke. When I plotted...

Just measuring the travel on the sensor is part of the story. You also need the leverage ratio as that affects how wheel travel applies to sensor travel. Or shock travel. The more progressive the leverage ratio is, the bigger the non-linearity between the two. Measuring wheel travel is also a big question - how to do it reliably? Clamp the bike horizontally and move the rear wheel upwards and measure vertical travel? Measure travel along the path (even more complicated)? It's not as easy as with a fork and could change everything I mentioned above. Or is the whole...

Yup you can use linkage in the same way and just pretend the sensor is the "shock" and calculate the wheel position relative to shock position from there. You can manually calculate a shock position reading later on if you need that but you will probably only have measurements for one or the other in the "raw" data. I think BYB has added live sensor readings as well in the new kit, so you can mount the fork sensor to your rear axle and take the measurements that way.

I'm aware of that and am usually doing that in Linkagedesign to get proper rear wheel readings for my BYB kit. But if you use sort of "random" points between your rear and front triangle (as pictured above on that crestline), you get (at least in my mind) superfunky sensor displacement that has nothing to do with the shock movement...
This is where the argument for measuring at the wheel comes from - you are correct when looking at % sag at the wheel, but the change in rate through the stroke means you have an inversion of % shock stroke used vs % of wheel travel used. Ie on a progressive bike, 25% shock sag might equal 30% wheel travel and 75% at the shock is 70% at the wheel. But on a more linear bike 30% at the shock might be 25% at the wheel.

Back at it again creating his own hype by saying "don't believe the hype" and saying that he's going to change the mtb world. Not quite.... Setting sag is not that deep, I've done this with measuring the shock sag and just looking up what sag that is at the axle using a linkage model on the computer (cost 0€).

I‘m on Spesh 2FO DH and actually measured them vs a couple of different brands (Fox, CB, 5.10…) at my local shop and found most cleat channels on gravity shoes to have about the same depth +\-0.5mm (depending where you measure / have the cleats mounted). I totally get that it’s a personal preference, as some friends happily ride some...

Have always been on flats for the past ~20 years and been keen to try something "different" the last summer and struggled hard to finde a clip pedal that feels like you're actually standing solid on a pedal - and not twisting around on a 5 cent coin during a descent. Pedalling was always fine and I prefered the definitive...

I like the vertical scroll format way more than the slide show! Way easier to browse on mobile.

Could also be a more subtle hint to MS (ex-Mondraker) Racing (wings in their Logo, from Austria / RedBull connection) going to Intense (new bike seems to work well, their Programm has been on Intense frames in the past)

I second that, rather a seat angle >75° and a more upright climbing position, that having all the weight over the rear axle when things get steep on the uphill. Having just spent two days on my DH bike (445 reach / 45mm stem), which felt weird on the first morning, I quickly realised it was just a much more...

I'm currently riding a Medium ("longer") Nicolai G16 (R502/S608) at 175cm height, but have a fairly high ape-index (185cm wingspan). Bunny hops and manuals took a couple of tries to get the timing right (felt really impossible on my first ride), but feel pretty normal/natural now. Seated climbing is definitely an issue as I felt my lower back for the...

I'm about to decide the frame size for my next bike and found some interesting points in that discussion. I'm 175cm (5'9) tall with a 82cm (32') inseam and 184cm (6'05) wingspan, which means I've got fairly long arms & legs for my height. My current trailbike has a 432mm reach paired with a 50mm stem and feels smallish for...
