Eminent Cycles Launches the Haste - First Look
@pinhead907: You're right, I'm around 6'2", so I'm largely talking about L/XL frame sizes, rather than trying to forcibly fit mile-long chainstays on everyone's bikes ;) Then again, most bikes have 435, rather than 425mm CS now and the world didn't end, so slightly longer CS probably wouldn't hurt anybody. Short rears are a genuine problem on larger frames, though. My point about Santa Cruz wasn't that they aren't a valid comparison (they're probably quite a good one), but they've spec'd some pretty nonsense CS lengths on bikes like the Chameleon, so comparing another bike to a Santa Cruz doesn't guarantee that its CS lengths aren't nonsense too. They seem to still be in the rut of spec'ing short CS across all their bikes, without thinking whether that's actually the best way to do things. A lot brands only make one-size rear triangles because it save a load of cost on carbon mould tooling, but it's a silly way to design frames.

Eminent Cycles Launches the Haste - First Look
@pinhead907: Santa Cruz are not a good guide for chainstays though - the new Chameleon hardtail has 415mm 'stays (adjustable up to 430mm) and a 73 deg seat angle on every size, S through to XL. I'm 6'2", on a hardtail with 425mm 'stays and a 72 deg SA; you basically have to kiss the stem to keep the front down on middlingly steep climbs, so a shorter rear, even with the steeper SA, is not a good idea. If you think about the frame as a lever, pivoting about the rear axle, with your weight through the BB, the shorter the CS, the less leverage your weight is exerting on the front wheel, so short rears actually shift grip away from the front, at which point all you can do to restore it is lean forwards, putting more weight through your arms, which will make arm pump worse and have you OTB much more easily. Besides, every brand scales their front triangles across the sizes, but only some (Giant, Norco, etc) bother to scale the rear to match, so handling isn't consistent across most brands' ranges and tall guys end up with bikes which climb horribly.

Pinkbike Poll: What If....?
- Press-fit creaking isn't the only annoying thing about them: you need more complex tooling/methods to actually get the BB in and out - I would be tempted by a light gearbox, but if that's at the expense of durability, there'd be no point. I'd want to try one out too , bearing in mind a lot of people reckon gearboxes and hub gears can feel "draggy" - The pedals thing will probably always be personal preference. I like flats and my iffy knee probably does too - What does automatic shifting actually bring, in terms of benefits, for 90% of riders. Niche applications, but I can't understand why anyone would ever expect it to be mainstream - Carbon still has the problem that you can't verify its integrity (voids, delamination, dry fibres, etc) without ultrasound scanning your bike after every crash, knock, etc so it's just not a very end-user-friendly material. Getting one season out a £3,000 wheelset still doesn't sound too good, either - I'm 6'2" and have size 13 feet, so the idea of anything being designed to fit me "just right", out of the box, is an entirely foreign concept. Knob-twiddling isn't the most fun thing to do on a bike, though, so I'd take the 95% - This is a silly idea; anything that limits a rider's options is a step back, isn't it? Knacker a fork, or wear something out, then have to send the entire bike off, or buy a new one? Not for me, thanks

Riding Rigid is Ridiculous - Opinion
It's horses for courses, basically, isn't it? I could replace my 140mm hardtail with an EWS-capable bike and all I'd actually end up doing is steamrolling all my local trails, to the point where any tech-y and fun stuff breezes under my wheels without a squeak and I get home 30 mins earlier, having had less fun. You probably can't expect to take a rigid bike to your local enduro and still enjoy it, but even tame trails can become a lot more exciting, when you don't have that suspension safety net. I've done a lot of what is essentially CX riding recently and it's amazing what the combo of speed, a high saddle and hard-to-reach brakes does for injecting some exhilaration into the bike tracks

Carbon Fiber Valve Stems, An Improved Dropper, and 6D's Updated Helmets - Interbike 2017
@chasejj: I understand the concept of wheel balancing ;) My point is that riders mess about with tyres, tubes, rim tape, sealant, valves, foam inserts, procore, the occasional tyre plugs/boot, out-of-true wheel, etc which is all guaranteed to affect wheel balance and yet it's not even close to common practice to balance bike wheels. That's not surprising though, because it doesn't matter - ride down anything rougher than a tarmac road and the feedback from the trail will completely drown out any feel of a several-gramme wheel imbalance. I reckon I might be able to tell on my road bike, but even then, old/cheap bike computers with wheel magnets make no noticeable impact on wheel balance, so why would you expect to notice shaving 3 gramme off your valve stem? I'd be willing to bet most professional teams don't bother either, considering they're usually preparing 6 wheels per rider, per race run, before you even consider practice and quali runs.

Carbon Fiber Valve Stems, An Improved Dropper, and 6D's Updated Helmets - Interbike 2017
@mgolder: You know it'll be recycled (or at least not dumped, if the frame is ever actually scrapped) because recycled aluminium is very valuable. Think of all the aluminium cans people use and then consider that extracting aluminium is several times more energy-intensive/ expensive than melting down old parts - you don't want the raw material for billions of cans to be any more expensive than it has to be. Machining shops do literally sweep their metal chips off the floor and sell them, because that's perfectly good material that other people can re-process and use.

Once people are shoving foam inserts, sealant, glitter, etc in though, I'm not sure wheel balance is ever particularly good, not to mention lumps of dry sealant, tyre plugs, running a bit out of true... I don't know that you could really tell the imbalance when you're riding any sort of off-road trail
