im looking at getting a med frame, and am wondering if I can work with a bike yoke 160 dropper post, that the new hd4's are coming with. I have a short inseam 29-30", and am wondering if the bike yoke dropper can be fully inserted into the frame. anyone have this short an inseam and riding a size med w a 160 dropper? thoughts?

Mine has the DPX2 and I haven't ridden a X2 but I just converted my Fox 36 to a coil and it made me want a coil shock in the back because of how much better it rides. Not really an option on the HD4 and every review I have seen says the X2 is way more supple than the DPX2. If it were me, I would get the X2.

Curious what pressures/sag people are running for fork/shock. With gear/water/me, the I'm adding about 150lbs. Thanks in advance.
What shock Bob? The DPX2 seems to take more air pressure to get the same sag as the X2. I am 170 and it takes 225 PSI for 30% sag with DPX2.

My Fork I used to run 72-73 PSI but I switched to the Push ACS3 coil kit a month ago or so. WAY better than air.

Hi all-

I'm having trouble getting my shifting together after assembling with the new xtr build. I can't seem to get it to shift from the smallest cog up the next larger cog. one more shift and it jumps up to 3rd smallest cog, then all other shifts up and all the way back down work well. wondering if i have an alignment issue or something. LBS is looking at it and is mystified as well. anyone run into anything similar with new XTR kit? thanks

Thank you guys for the reply. Well I got the bike yesterday and put on the new crankset although have a quick question on bottom bracket spacers. With the dub bb the bike only has spacers on drive side and when I screw in the dub adjuster on non-drive side it's uses all tbreads and feels like I should have another spacer on the bb or something. Anyone know what the normal is? Thank you

Olie12, I am running the XO1 drivetrain and have a 2.5mm inner spacer on the non-drive side (left) and a 2.5mm inner spacer on the drive side (right). Also, a 4.5mm outer spacer on the drive side (right). You may be missing the 2.5mm spacer on the non-drive side (left).

For reference, check the SRAM user manual:
