Review: Knolly Chilcotin 151
@farkinoath: so basically you're saying we should be using old brake levers as reverb remotes? Someone try it and report back.

Tsuga Announces the Eldorado Hip Pack Collection
I ride with 1-2 bottles in my waist pack (Mountainsmith Tour 6L) pretty regularly. The weight is super secure and it doesn't feel awkward at all. I definitely prefer it over a backpack unless I *really* need a 3L bladder (all-day desert rides, mainly). If there are places to refill/purify water along the way it's enough for a full day ride. IMO the Mountainsmith design is still the best out there after 20+ years with only minor tweaks, and the price is reasonable. This modular design is interesting but it's a lot of money vs just putting some decent compression straps on a bigger waist pack.

First Look: Actofive's CNC-Machined Signature Cranks Are a Work Of German Art
@conoat: True in principle, but I've never seen the non-drive side Shimano crankarms fail - it's always near the giant/wavy bond joint that forms the drive side spider... where the outer Al crankarm piece forms a closed moisture trap over the hollow steel spindle (shocker!). So moisture enters through the open end of the spindle on the NDS --> migrates to the drive side --> gets stuck between the bonded pieces --> forms a battery with the steel --> disaster. All that is to say... I *think* the NDS crankarm concept (which is also basically the same as the Hope RX) is probably okay since there's nowhere to trap moisture between the two bonded parts, and the bond line doesn't touch steel to form the battery. But again... given the choice I'd probably just not buy a bonded crank from Hope or anyone else. Unfortunate because I'm pretty sure the Shimano ones used to be welded and/or just formed from a hollow tube.

Yeah idk, from the times their bike has been featured on PB people seem to have a huge hard on for tool marks. I don't get it. Also there is no effing way I would ride a clamshell-bonded Al frame. Crazy.

@conoat: the Hope RX cranks are bonded (https://www.youtube.com/watch?v=UHU3EaAPUR4). Looks like they engineered in a MASSIVE bond interface though (think two C-channels nested together, not just a clamshell like what Actofive appears to have done). The bond line is almost the width of the crankarm and it's perpendicular to pedaling forces. Still don't know if I'd buy a bonded crank for mtb though...

Yeah the idea of them being bonded sounds sketchy to me. I know it's *probably* totally fine, as long as they made some big ass lapping faces for the bond line (like in this video from Hope - https://www.youtube.com/watch?v=UHU3EaAPUR4). But I also don't see those big overlapping faces in any of these shots. It kinda just looks like they're bonding around the perimeter of the clamshell which sounds... bad. At least the Hope design puts the shear plane perpendicular to the main forces from the pedal.

I thought shimano hollow cranks were made by forging an aluminum tube, but I could be wrong. There's also this patent I found, which sounds crazy... idk if they actually use this method though. AFAIK they don't cast them. https://patents.google.com/patent/US6145184A/en

First Ride: Marzocchi's New Bomber Air Shock
@skierdud89: I don't really understand your fixed pressure analogy... if you choose to run 25% sag instead of 30% on a self-equalizing air spring, your negative spring behaves the same and your overall spring curve has the same shape. On the Mara the shape of the spring curve changes (harsher near topout, less supportive at mid travel as you increase pressure - around 7:30 in this video has some graphs https://www.youtube.com/watch?v=3HeL5NNHbFw). It's awesome that the damper is super tunable, and I can understand why people like that. I'm not at all surprised that it works great for some people, but knowing how the air spring works would I recommend it to someone who doesn't want to play with shim stacks? Absolutely not. The decision not to just put a dimple on the air can is bizarre and I think ppl who need higher pressures have good reason to steer clear. The reviews I've seen (blister, bikeradar) seem to have exactly the issues you'd expect from this spring design, so I don't think this is a case of nitpicking one little thing about the design. There are far more people who just want a consistent linearish spring curve than there are people who will actually ever open up a shim stack and mess with it. It makes total sense that people who love tuning would rave about the Mara, but that's a reeeeeaaaalllly tiny fraction of all the potential customers.

Now Finished: Ask Me Anything with Chris Ball on Organising Future World Cups
@gcrider: totally agree about their youtube content. I have not seen their paid road/CX live race coverage but I've heard it's actually pretty decent. Like I said, I'm perfectly okay with paying to see decent race coverage, whether it's from cringey ass GCN or from Red Bull (who, to be fair, has plenty of cringey but well produced shit of their own all over RBTV). In any case, it seems completely insane for them to have said "let's do an AMA!" without even being able to say "WC coverage will be on GCN+", or whatever. But to people in this thread who are losing their shit wondering whether we'll have to pay.... those ppl need to grow up and use some common sense. Of course we'll have to pay. The mere fact that he's saying "there will be a mix of paid/unpaid content" means that the premium coverage will be behind a paywall.
