Ask Pinkbike: Over-Forking, Missing Bolts & Anti-Squat Energy
I could be wrong, but I don't think preventing squat (anti-squat) necessarily consumes energy as you are suggesting. Let's imagine the simplest system. To get rid of rider movements and weight transfers like legs flailing around we replace the rider with an electric motor on the crank. The bike has 100% anti squat. When we turn the motor on, the bike goes forward and has no vertical motion. If there is no vertical motion then no work is done. If no work was done in that axis then no power was consumed. It just zeroes out. Now imagine a bike with 200% antisquat. The bike goes from sag, to less than sag when we turn the motor on. Work was definitely done in that period (some of which converts to heat in the suspension). Now imagine it's a meatbag pedaling. You are like the worlds shittiest electric motor, you output a sinusoidal power form. The suspension anti-bobs you up as you push down on the pedal, then as you go past 12-6 o'clock the suspension goes back to sag and then you repeat that 180 times a second for a cadence of 90. On flat ground your vertical axis would look like a pogo stick. That's a lot of work you are doing which doesn't make you go any faster! 0% antisquat is the same thing but in reverse (this is harder to imagine, which is why I started with the 200% example). A lot of bikes have more than 100% antisquat (at least in certain gear/travel combinations). So while there is such a thing as too little anti-squat. There is also, definitely, such a thing as too much. "But my bike has 100% antisquat and I still see my shock moving!" Yes, cause there is more going on than just your pedal force input. You are literally flailing around on top of the bike, so that causes shock movement too as you are changing the center of gravity of the system etc. This is why we should all ride rigid bikes and enduro is dumb. QED Now is that everything going on? No, but I think it's a pretty quick and simple explanation of a lot that is happening.

Pinkbike Poll: Would You Rather...? Quick-Fire Edition
Who are the animals who work on BBs without tools? That's why most people say press fit is hard to work on...because they don't have the tool. It would also be pretty freaking hard to work on a threaded bottom bracket without any tools. Ask any good mechanic at a bike shop and they will tell you that replacing a BB86 BB is no big deal, it's actually really easy. I've had press fit in my: Pivot 5.7c, Intense Sniper, Giant Defy, Pivot Mach 6 I've had threaded in my: Santa Cruz BLT, Ibis Ripmo, Santa Cruz Nomad I've replaced 1 of my press fit bottom brackets ever--in my 5.7c after about 3 years of riding in SoCal. I've replaced my threaded bottom brackets every 3-4 months in every threaded bike I've had. I've tried ceramic, I've tried steel, I've tried Shimano, Sram, BB Infinite. All of them get creaky or crunchy way too soon. I have no idea why. To me they are both very easy to service if you have the tool. Pressing in a press fit bottom bracket with the proper tool is actually really satisfying. It's so smooth and perfect! Press fit looks better, is lighter and stiffer too. But I get that a lot of bikes are built with awful tolerances and it's never going to work well if the frame isn't made well. People are just blaming the wrong thing. Blame the brand for making a crap frame. Don't blame press fit. Your bearings are still press fit into your threaded BB...the main advantage of threaded is it is better at dealing with a frame with poor tolerances.

Zerode's Katipo is a Gearbox Equipped 29er With Serious Intent - Eurobike 2019
@High-Life: Having ridden a couple, It's not always as good at shifting under load as a normal system, but you can for sure do it. The big thing seems to be that as the gearbox wears in the shifting gets better. A lot of reviews are from people that just got the bike and the gearbox isn't really broken in yet. I rode one that had a few thousand Ks on it and was very surprised how much better it shifted under load than the brand new one I rode a couple months before.

Poll: Has Climbing Become Unfashionable?
In some places, like where I live, singletrack is very limited. I ride up fire roads because I think it's trail courtesy. I want to go have fun going downhill, and since there are only 5 legal singletracks in this 20,000 acre park (yeah, it's insane) I don't really want them to be two-way even though they are. I think most riders here tend to agree. So yeah, fire road climbs in the hot sun for us.

Improving Mountain Biking One Design at a Time - Sunday Comics with Taj Mihelich
E-bikes are always going to have a lot of appeal to casual or weekend warrior type cyclists. Even for the bros who want to use it as basically a self shuttle. E-bikes are going to take over, what will remain will be the lower cost alternative, race bikes, and a niche for the guys who enjoy the fitness side of the sport but don't race. If you don't like fitness, and training, and don't race--why not have an E-bike?

Review: The 2019 BMC Fourstroke 01 One is a Purebred XC Race Rocket
No true mountain biker would ever be caught dead using a lockout! We must constantly remind our readers how superior we are by dismissing their usefulness! Only weak, insufferable, fabulous, spandex-clad roadies use lockouts.

First Ride: Pivot's XC Race Ready 2020 Mach 4 SL
Yeah, can we keep our XC race bikes as XC race bikes and not try and make them into lightweight enduro bikes? How else are we going to justify buying like 8 bikes anyway?

Counterpoint: We Need Suspension Lockout Levers
All this anti-cable propaganda. Cables aren’t that big of a deal, and if it is there are systems like Fox Live which minimize the cables and I think everyone would be shocked if Rock Shox didn’t get AXS suspension in a year or two. Fox live sounds EXACTLY like what the author wants. Make a bike that is amazing downhill, put fox live on it and it will pedal great too with simplicity for the user. But no one talks about the alternatives or what could be done.
