Ican P8 full suspension build

[R_Pierce]

my p8 build is progressing.. i got almos all parts. i went with 29er ican 35 mm rims with 2.4 tires the shock is monarch plus rc3 200x57. i'm almost sure the fork will be rockshox pike. i wonder though should i go for 140 or 150 mm. what head angle do you guys have with 140 forks? i d like to get mine close to 67.5 at least.. will 150 be ok with 29 inch wheels?

It would be fine on a 150 fork.  I just responded to your post on MTBR as well, but mine is a measured 67.8 degrees with 27.5+ tire and a 140mm fork.

[boo]

thank you for the help!

Whats the difference between the a P8 and P9? Are they both 29er capable?

Yes.  Go take a look at both of their geometry sheets.  You will see the difference.  P9 is designed for more travel.  As well as a slacker HTA.  Different size seat post, etc.  Just go look at the geo sheets for each and you will see clear differences.

The seat tube looks so slack! Theres no way thats 74 degree. What is the travel for the 29in version?

Actually, it is.  You need to remember how seat tube angle is measured.  It just looks super slack because of the bend in the tube.  Draw a line from BB center line to top of seat post.  And there is no 29er version.  The same frame fits both.

Or were you referring to endo_alleys post?

Mine will be a 29er this year.  150mm front fork and a 200 x 57 rear shock.  I can measure the actual rear travel and let you guys know.  But Im assuming its around 130-135mm of rear travel with the 57mm stroke.

True true... my eyes fail me lol. Im debating on a P8 or P9. Im leaning on the P9 even though a P8  would be a better choice.

I'm quite like you, numbers say P8 but looks say P9.
I will be using moderate 29x2.25", a shock with only 50mm of stroke to set the P9 with 135mm rear travel and a 140mm fork.
I will have to wait for a few months to start ordering parts, but I have almost everything checked.

What makes your guys want the P9 over the P8?  travel? 

[Silverado123]

Longer travel, extra baddassness... more is better right!  Thats what she said! Lol

Looks like about 136mm of rear travel on the P8 with a 200x57 rear shock.  Also just took my fork out to 150mm.

What is your seat angle with a 150mm fork. Isnt the frame designed for a 120mm fork and that would give you a 74 degree seat angle?

Yes.  Frame is designed for a 120mm travel fork.  I don't want a way to accurately measure the seat angle.  But it will be slacker obviously.  It hasn't caused any issue climbing at 140mm.  It will be fine at 150 as well.

Thats cool. Im trying to compile pros and cons to the p8 and p9. I like the geo better on the p9  but i have a rad shock and dropper that would fit the p8. Decisions, decisions...

Honestly if I was to do it all over again and had no parts, I would buy the P9.  But, since I have a shock and dropper that wont fit that new frame...  Ill stick with the P8.  Not to mention the bike feels like its got a lot more travel than 135 in the rear (with the 200x57 shock).

Overall I cant complain about the bike really.  A little slacker might be nice (I actually ordered an 18mm spacer which would get me about another degree or so of slackness at the HT)  But am unsure if I want to put that on there or not.  And we have some tight twisty single track here, so the extra slack HA might make it a bit tricky getting around the tight twisty stuff at slower speeds.
