Banshee Releases the Enigma, an Alloy Hardtail Built for Versatility
100% agree with you. I'm on a Spitfire and I love the thing.

Banshee Releases the Enigma, an Alloy Hardtail Built for Versatility
@topherdagopher: I'm not putting anyone down at all. Cross pollination between marketing and engineering, specifically FEM/FEA is rare. I think it's pretty safe to assume 99.9% of people in marketing can't draw up a hub in CAD, and then run FEA. Likewise, there are many engineers who don't have the skillset for, or care to take a marketing role. That is just fact - I am in no way putting down one profession or the other. Clearly the OP and yourself are in a bit of a different situation, where you are an engineer and marketing couple, or you're shacked up with a marketing person in an engineering field with engineering backgroud, but that is a minority. We'll rewind to my original point. The OP trivialized the FEA bit. I don't think that's fair, as not all bikes undergo FEA. The guy who wrote the article is an engineer to the best of my knowledge, and he though it important enough to note. And having seen FEA being run myself, I think it's pretty interesting stuff that I certainly can't do!

I'm not sure it means the "just used a computer". Unless you can do FEA in Microsoft Excel or Paint or something? More like...and engineer sat down at a computer with engineering based programming, and engineered a bike himself. Which isn't always the case for every bike! As an engineer that may seem like pretty low hanging fruit, but can your marketing girlfriend run a FEA analysis?

1000% Banshee has ways been a top pick for me. So much attention to the details. Keeping aluminium sexy.

First Look: DT Swiss Introduces New FR 541 Rim
@gabriel-mission9: funny, I was chatting with an ex enve engineer about this last night. I'm in Bend currently meeting with some product development and business development folks, working on a project. We got to chatting about bearing bores and how really high tension can actually create slop in bearing bores - talking like, 150 kgf. Enve was doing this "for stiffness" when they first came out, and I think he kind of eye rolled while making the comments (because it was marketing BS). I asked if they did the testing and he actually said they did, and conceited that once you get to a reasonable tension where things aren't going slack, adding tension makes no meaningful difference to stiffness. Messing with spoke tension to create more compliance is BS. Too high or too low just causes issues with hubs, rims, and spokes themselves.

@wyorider: I've got a guy dropping na wheel off in the coming week, where his Sapim CX-Rays are breaking off one by one at the elbow. It's a big name carbon brand factory build. Fantastic spokes, some will tell you the best. But the quality of the spoke doesn't matter worth a crap if the wheel is poorly built. Uneven tension, low tension, and your spokes will not come close to their potential. They will fatigue out fast.

@wyorider: certainly it CAN happen. That said, I see very very few people return with broken spokes from wheels I build. In the last 5 years I've built hundred of wheels, and I have had 0 instances of broken spokes from fatigue cycling and impacts. Things flicking into a wheel, that's obviously uncontrollable. I expect factory wheelsets to break more spokes, by orders of magnitude, as they are usually poorly tensioned and not stress relieved, as mentioned previously. I also see some breakage from some carbon rim manufacturers rounding spokes down and leaving too many threads not engaged in a double square.nipple.

@wyorider: broken spokes - more like pretty frequently, when wheels are poorly built and not properly pre-stressed/stress-relieved. And most wheels are poorly built, with no real pre-stress/stress-relief routine. Also, lower tension is an absolutely terrible way to achieve a softer ride feel. "Tight-enough" and over tensioned is a pretty narrow window, and if you are inside of it, difference in tension makes practically no difference to the feel of a wheel. If you want softer wheel feel, then play with spoke gauge/thickness and number of spokes.
