Giant Trance Advanced 1 - Review
@kraf: The steering myth is based on the belief that smaller input movements, regarding a short stem's faceplate arc of movement, results in a larger change of the wheel's turning angle. In the big picture, no matter if it makes steering faster or slower, the effect is so small that it should not be worth even debating. The "mechanical trail", which is related to the HA, wheel size, fork offset, etc. should be the primary factor to consider regarding steering sensitivity. The "auto-centering" effect at speed from a long mech. trail (slack HA) slows down the steering for DH bikes for stability--the myth suggested that a short stem will make the slack HA more manageable by making it more sensitive to rider inputs. In reality the longer leverage from a wide bar currently does that job; a long stem would also do the job, with a narrower bar, considering the fact that you steer from the grips, not the stem faceplate. This combo is interchangeable, but it's seemingly just *out of fashion* to ride a long stem. Choosing stem length based on riding style (XC, trail, enduro, DH) and fit is also another questionable trend. Stem length should be first considered for performance, primarily to tune weight bias according to what bar width you settled with. Riders and trails can only cope with so wide, and if they find disadvantages with bars wider than 750mm, what disadvantage is there with running a 10mm longer stem, to get the handling of running a bar that's 20mm wider? The body is really accommodating to "fit issues", but handling quirks are something else entirely. Tuning the weight balance affects "steering", in terms of oversteer and understeer. People say they'd rather have the rear slide rather than the front, but the bike would be faster and easier to handle when not biased towards either. Might find yourself holding uncomfortable riding positions in tech sections, due to disrupted weight balance, only to breathe a sigh of relief once clear of technical challenges--shouldn't you relish technical challenges? Does having a well tuned bike make it too easy, and/or less exciting? I suppose an expert might appreciate a bike that's more of a handful to control, to artificially increase the challenge, while still being more enjoyable all around than a less capable bike (a high end FS vs increasing the challenge by riding a cheap HT). I can imagine an absurd amount of finely balanced bikes being compromised by customizing in the name of fit and trends. There's a strong belief that manufacturers designed their bikes for some specific proportioned person and that the odds are better to win a lotto jackpot than to have your own body fit the stock bike. Despite a manufacturer's efforts of lengthy prototyping and testing phases, people seemingly just have a thing for hot-rodding and ignorantly disrupting the balance, replacing setback posts, stems, bars, and whatever else, influenced by reviews like this. Are there real reasons behind the act of spending for a very minor change that may be no better? Psychological benefit? Lengthening the front center, without changing the rear, makes the bike more rearward biased. The longer downtube adds additional weight on the front, but some of that additional weight gets shifted rearward by the shorter stem--there's an increase in total weight on the wheels combined. On that subject, with bikes growing in wheelbase, weight bias is less affected by small changes in the cockpit. Unsurprisingly, the longer bikes ride with more confidence, but it may come as a surprise that they *corner faster*, especially in tight switchbacks. This is contrary to the former popular belief that long wheelbases were terrible in corners (steer like a bus). Can choose whatever stem length you like with 1200 or even 1300mm+ wheelbase bikes; it won't matter, since the rider weight at the BB, from merely standing on the bike, becomes enough to dictate handling, with the sweet spot of rider fore/aft positioning becoming huge and forgiving. These bikes come with their own issues though...

Fox Float DPX2 Shock - First Ride
Fox has seemingly copied the best tech from other brands, but the one piece of tech I'm waiting for is the replacement of the IFP with a bladder (ex. DVO Jade, CCDB Inline).

@RichardCunningham: Thanks for the reply. Yes, this isn't the ideal place to discuss it, but since we have peoples' attention, here are some of my points: Short stems being hailed as an upgrade is a trend from days of steep HAs. There was just too much weight on the front and once all momentum was lost, shit happened. Slack HAs require more weight on the front. That's gained from both stem length and handlebar width, but you can only go so far on bar width, so you need to also increase stem length. With enough weight on the front, thanks to bar width and stem length (headset to grip distance), you can stay in a more relaxed centered position, rather than tentatively forward. 10mm of additional stem length is worth 20mm of additional handlebar width. Riders compensated for low weight on the front with big slow heavy tires up front. Longer reach (longer downtube), increases weight on the front wheel, so a shorter stem is possible. Problem is that the weight bias is shifted more to the rear. With excessive rear bias, the rear wheel sees more abuse, increasing risk of flatting and other damage. Short stems making steering more sensitive is a myth. I'm sure people have seen an illustration showing how much the face of a stem moves when you turn the wheel the same angle, with 2 different stem lengths. You're in for a surprise once someone convinces you to instead see how much the grips move when you turn the wheel with the two stem lengths. Hint: it's all based on the headset to grip distance. Steering feel probably should be managed by the fork offset, but that's a whole other issue to get that unlocked/adjustable.

@RichardCunningham you should know better than to perpetuate all these misinformed geometry prejudices. The reason you were pleasantly surprised by the bike might be because your expectations of it being undesirable based on the #s were straight up wrong. The shorter the stem the better, up to DH lengths? The wider the bar the better, up to DH lengths? Short CS length improves climbing traction? According to another review, long CS length does too. 67d HA is conservative, slacker is better, up to DH angles? 63.5 SA is conservative, steeper is better, up to the steepest you've seen (75?)? 434mm reach is conservative, longer is better, up to the longest you've seen (Geometron, or more modest like Whyte T130?)? Shorter bikes require you to ride a certain way? Having made frames yourself, and having in depth talks with experienced designers like Jeff Steber, you should know geometry and all these component lengths is a juggling act, with dozens of things to juggle at once, to get right. Don't see the sense in trying to deceive us, unless you're using satire...
