Just an FYI, this was a super helpful article for me as I am building an Arrival right now. Cables were a PITA and the Park Tool cable installation kit's magnetic ends were too big for any of the brake or cable frame openings so I wouldn't buy that set. Magnet was also mildly weak, so probably no better than what you purchased and $25 bucks more.

Great article for discussion. I'm an orthopedic spine surgeon and so thought I might comment on some common misconceptions about Full Face Helmets. I can't find any data that shows they are better or worse at preventing spinal injuries and certainly in my practice I have found most patients with a spinal injury were wearing half shells (granted their are a lot more riders wearing half shells). In the US NICA doesn't allow racing for kids with a full face, but in our league we give exemptions regularly. This rule is in place due to a fear that in the setting of a spinal injury a full face helmet is more dangerous to remove than a half shell. First if you suspect a spinal injury only EMS should be removing the helmet and there are safe ways to do so (including cutting the chin bar off). Second, there is no data on this for mountain biking I can find most people are using old football helmet data. I do see a lot of facial injuries in mountain bikers wearing half shells. I'm not sure full faces prevent concussions better (I've had concussions in both). As far as not looking cool that appears to be regional, we have a lot more folks I see on the trail starting to wearing FF and we all wear glasses. If you are going to wear goggles you better have some serious steeze. What do I do? I wear a TLD stage most of the year and if I am going on anything gnarly. July and August I tend to wear a half shell. Coaching I tend to wear a half shell. I've never had a patient that regretted wearing a FF helmet though, so I should probably just wear one all the time. 

PS: I also see a lot of elbow injuries, and I hate scrubbing for surgery with road rash forearm (our trails are cheese graters) so I wear pads (I have sets of Leatt, TLD). Operative elbow fractures tend to have inferior functional outcomes compared to knee fractures.

They do I, I have one one the back of my trail bike. I don't notice any less traction than an Aggressor to be honest, and it rolls better. I don't think they make the larger widths:(

Thanks for posting this. Pseudoscience used for fear mongering has no place in these times. If any single thing has been thus far proven to be protective from Covid-10 it's maintaining normal body weight and stopping chronic co-morbidities such as diabetes, hypertension, heart disease, and poor pulmonary health. Exercise in all forms is vital for this.  It's currently our only good defense consistent with normal societal function.

Just know there’s going to be a flat and make sure to use that time for good natured ribbing about pump technique and how somebody’s significant other isn’t putting out enough.

1. I think all things MTB are cool. That being said, 2. This is kinda just a redbull commercial. 3. I’m concerned Max is the best at what he’s doing because no one else is doing it.

A quick release mechanism makes sense in racing formats where seconds count but you don’t automatically lose if you flat. For me, since I ride with everything including derailleur hangers for my buddies bikes, I’m always going to have an Allen wrench.

Dave, are you getting enough riding in?  You've strayed from sarcastic lately and seem a little more nihilistic and despondent?

I have had an Aggressor DD do this, it is from the bead being stretched. I think you are fine to run it if it doesn't bother you, but at some point it will stretch to the point it won't seal/seat on the rim and will blow off as you pressurize it scaring the crap out of you and showering latex sealant all over you. Ask me how I know...
