Added a comment about feature Modern Mountain Bike Geometry Defined - Transition Explains Effective Top Tube Versus Reach 2/7/2015 9:23 PM

This new concept of long front center geo is simular to the Gary Fisher genesis geometry circa 2001.The idea was to move the bottom bracket to the rear. So if you move the bottom bracket 1" to the rear then your 17" chainstay just became 18". This pont has been missed here, you can not just make the chainstay short to get the wheelbase back to good again. Look around most 160mm bikes have 29" sized wheelbases (and effective18"chainstays).
Just like Gary Fisher suggested, you will need a short stem to get your riding position to the rear as much as possible
(65mm stem-25mm=45mm stem) wow thats the same distance that the BB was moved rearward, go figure....
The way I size a bikes top tube is from the bottom of the headtube via a horizonal line to the seat tube (or just above it), This removes the head tube length variable and also the saddle height variable at the same time. i like the idea of measuring the down tube to understand BB position. I thought of hanging a plum bob from the seat to see how far the BB has been tucked backwards. The longer reach numers are part TT length and part BB rearward. In both cases the wheelbase gets longer, now you need 31" bars to control it all.

Thank You SDMTB'er for the pic of your cable set up, it looks vey close to mine. also thank you for reminding us that we do not spend all of our riding time standing on the pedals with the dropper down. The seated riding position is very good IMHO on this bike and the cockpit longer than some bikes with more reach. I vacation in Oregon where its common for me to do 35+ mile deep forest riding and I do a lot of trail riding as well so I did not want a long wheel based long reach bike. I am very glad that Pivot has thought about the other 75% of riding that most of us do. my local riding has lots of steep log and jump infested trails.. this is my only bike

Done right this cable routing will give you zero rub. you will need to make "stand offs" with a small rubber tubing and a zip tie. one year later ...NO RUB !

OK my bad I misread the sag spec on your write up, you guys spec it as 20mm not 20%.

The 66 degree head angle is the spec for running a 150mm front shock so the 160mm Fox 36 should slacken it by .4 to make it 65.6. I have owned this bike for a year now and do not have any shifting issue, the cable routing provides a direct pull but you will need the be sure that the housing is as short as possible to mute the flex outward. I think there is a typo here because the recomended sag is 30% not 20% I pressure the Fox float so the O ring is almost pushed off after an aggressive ride. I'm 6' even with 32" inseam I run a large frame and it's a very comfortable fit for me. This bike is fast and handles very well, when riding with a group I will pull away from them in the courners... tighter the better
