Rather have a chin bar, preferably one with an open mouth port so I can actually breathe without restriction, and one that's tougher than the Proframe and Stage's.

Would be a plus if they did something to combat wind noise.

Stay off the jumps and drops, else you will learn what too much weight on the front feels like the hard way when you (and your bike) become a lawn dart. Can't wait to hear your complaints about your lower back being sore and your worries about buzzing your ass on the rear tire, from needing to shift your weight back, to compensate for the bike having too much weight up front.

Good luck figuring out why you can't copy Loic Bruni's riding style where he stays mostly centered and motionless besides his arms, because you think you should have chainstays that are 40mm longer despite having similar wheelbase... oh wait, you don't even consider the wheelbase, being picky instead about HA and reach.

I'm suggesting that the brands do the scale measurement for weight bias, not use some shitty FC/CS ratio that is meaningless. Hard to simplify it into easy math--I can't even imagine how they can even simulate it accurately. Most brands are simply guessing regarding where the bike's CoM is, with rider on board. How do they even determine what position to put them in, to consistently compare with all other bikes?

That's why I suggest the scale measurement, with a rider in an effortless/comfortable natural/neutral standing position, one that isn't pulling nor pushing on the bars.

This way, they can tune the CS according to the WB (or size), rather than simply keeping CS the same and adding or subtracting 1-2" to the seat tube and top tube for each size.

Santa Cruz making all their newly released bikes have adjustable chainstay lengths is a start. Forbidden is doing it right with their Druid. Norco is probably just guessing, if their Revolver is anything to go by. YT is starting to get it too. Seems that only Forbidden has CS dialed for S and M though...

The industry trend seems to dial in bikes using pro athlete feedback, who tend to be L (XC racers mostly XL). The SB150 is an exception, since they dialed it in for the EWS racers and arbitrarily called it a M, when such dimensions typically belong on a L.

I don't get your push-up comment. The ideal stance is a neutral one that uses your core and legs, with the arms not pushing nor pulling and not using your lower back to hold up your upper body. Coaches train up many kids using such a stance: it's called the athletic position. It's different from the bend at the waist position, which might have you doing push-ups/pull-ups.

CS too long has your lower back doing a lot of bump absorption as you are pushing yourself back into sort of an aero position, with butt over the rear wheel, in order to compensate for the 55:45 weight bias (by getting weight more rearward to make that equivalent to 60:40). If you don't, you have problems like the rear wheel taking a taller trajectory than the front wheel off of jumps.

All these long chainstays reminds me of that FIM E-Xbike race, where almost everyone was racing while firmly sitting their ass in the saddle. Are they forgetting the importance of fore-aft balance in vehicle dynamics, with this overly forward weight bias design?

The Phase is the exception. That one looks dialed. If only they did something as simple as putting scales under each wheel and measuring the weight distro and tried to design in fore aft balance with CS and WB length, get it more to 60% rear 40% front out of the saddle (maybe 65:35 in saddle), rather than 55:45 or worse (worse being even more forward, like 50:50). I'd expect 450mm CS for 1300mm WB. A lot of brands are getting it right with 435mm CS for 1230ish WB (430 for 1210, 425 for 1190, etc.).

Can't do much about the linear shock stroke without adding complexity. Rather have better geo, even if it results in less progressiveness in the shock. Just move the shock forward and steepen the STA to get more rear wheel clearance. Shorten the seat tube to 15" for the smallest size while you're at it, and cap the length to 18" in largest, because 210mm droppers exist.

Sad that the slack and long seat tube of this bike are considered compromises compared to Ibis and Santa Cruz (and more recently Spec).

I'm saying that if I were to buy a foam insert, I'd be more confident in my choice if it were based on comparison data like this, as opposed to just deciding based on weight, price, putting trust in my imagination/belief that it's "just foam", and from putting relatively blind trust in other peoples' opinions.

My comment was encouragement for doing such comparison tests. I also was making a joke about my shopping habits that I reluctantly do in absence of such data. Just thought it'd be unfortunate if this kind of stuff got so much negative feedback, to the point that companies would be reluctant to do more of it.

This is the kind of stuff I like to see, that gives me more confidence in my choices! Sadly, I doubt having data like this will do much to beat the prevailing wisdom (sarcasm), such as "it's just foam" or "it weighs less and is half the cost." Those who didn't pick CushCore will likely defend their choice, convincing themselves that "it works just fine" and "I haven't had any problems". "This many people [without CushCore] can't be wrong." Or they may resort to picking out the cases where CushCore didn't protect the rider from failure, even unrelated failures that any insert can't do anything about...

BTW, in another post, I posted a table that suggested that with the usual sizing method of increasing FC by ~20mm per size through reach, I'd generalize the CS should grow by 4.5mm to balance that out to have similar weight bias. That's not extreme, ... more »

In terms of scaling, I was considering how well it applies to NORBA XC geo ~42 inch wheelbase (1050mm in med) and smaller (DJ, trials, road), and Geometron geo 1325mm wheelbase and bigger. I was afraid that people would "round" the ratio to fewer digits. ... more »

My impression: the old man needed the royal treatment to even discover the experience of trail riding. I call that the "princess tax", similar to paying a premium for things since it weighs less. If I criticize the ebike, then I also criticize the weight weenism (for those who aren't milliseconds off from being on the podium). I rather just criticize that people give up too easily...

I'll also criticize that ebikes are just bikes with a motor and power source added. I'd be more impressed if they brought innovation/change that helped cycling as a whole. An efficient gearbox wouldn't be a bad start, but I think I'm dreaming still... doubt anyone would want to pedal a gearbox ebike without the power from the battery helping.

Not only that, but I'd go as far as arguing that short CS and short wheelbases are more suited to smaller wheels, since there's a synergy for where/how they likely to be ridden (tight techy trails). I still keep a 2013 Stumpjumper FSR EVO in my quiver, ... more »

Guessing they're saying it's a bad idea if you're going 27.5 to mixed. Not much to F up if you go 29 to mixed. I'm picturing the Kona Process 153 29 in med as a good candidate, that fits your specs.
