I'm really liking the MRP, its the Ribbon air. I'm going to play around with the air pressure more but right now at 60+/65- it is very plush but still supportive. Doesn't blow through it's travel or feel harsh. I've been on a Pike for the last couple years and my HD4 demo ride had a 36 RC2, I think the ribbon feels better than either of them. Pike was plush but lacked some mid stroke support, the Fox 36 overall felt good (and I didn't have a lot of time to tune it) but felt a bit harsher than the Ribbon.
Just picked up a size Medium XX1 X2 build to replace my 2017 Santa Cruz Nomad X01, size medium frame, Lyrik fork, Monarch plus shock, DHF 2.5 f, DHR II 2.4 r tires. 29 lbs 4 oz including water bottle cage and pedals.
I'm 5'8" and weigh 146 lbs ready to ride including helmet, shoes & 21oz water bottle. (138lbs in my birthday suite)
The HD4 is my everyday trail bike including lift service at ski resorts and jump tracks. I also have a 100mm XC bike for the less rowdy XC trails and longer rides.
Ibis 742 Carbon wheels DHF 2.6 tires, 18 psi front, 22 psi rear.
Quick note about this wheelset. Hub engagement is incredible, they're very stiff and you can feel them carving up the trail even with these big 2.6 DHF meats on there.... they're not too harsh at all. Hub engagement is perfect!
Bars cut down to 760mm, 40mm stem with 20mm spacers below the stem
Fox float 36 RC2 Fork: 56 psi, LSC & HSC full open, rebound 7 from full fast
Fox float X2: 155 psi, LSC 16 HSC 19 LSR 14 HSR 13, resulting in 16mm sag. I also have 2 orange volume spacers and a bottom out bumper.
The HD4 weighs 29 lbs 9 oz with water bottle cage, fender & pedals.
I should also mention, I swapped out the KS Lev Carbon dropper for a Fox Transfer 150mm dropper.
I've got just over 100 miles on the HD4 and it's starting to feel really good.
It took a number of rides messing around with different settings but I'm happy with where I'm currently at. I'm sure there will be many adjustments in my future. My previous bikes didn't have nearly the amount of tunability in the fork or shock. This is all a little new to me...
The bike, in its current settings, feels really poppy and playful but still very stable at speed. I still need to mess with the fork a little... sometimes at speed coming into corners I feel like the fork is diving (lacking support) a little bit and I'm sure it can be corrected with more time messing with compression and psi... I'm sure I'll get this all sorted out in the next handful of rides.
I've now had two rides with over 3,000 vertical feet of climbing in about 20 miles. Bike seems to climb really well and stays high in its travel. For a bike that descends as well as this, I'll take it!
I've ridden the HD4 back to back with a 2017 Pivot Firebird, 2018 Santa Cruz Bronson, 2017 & new 2018 Santa Cruz Nomad and I couldn't be happier with my decision to go with this HD4!
Other bikes I've ridden in the last 6 weeks but not back to back with the HD4 include, Pivot Mach 6, Pivot Mach 5.5, Rocky Mountain Altitude, Santa Cruz Hightower, Santa Cruz Hightower LT, Rocky Mountain Instinct and Giant Trance.
Of the bikes I've ridden in the past 2 months the Santa Cruz Hightower LT stood out as one of the very best in terms of do everything bikes but I wanted to stay with a 27.5 wheel size for my long travel bike.
I was stuck between the pivot Mach 6 and the Ibis HD4 and honestly could have gone either way. They're both really good bikes.
The Ibis HD4 just felt a little more poppy and I wanted to try this new crop of 2.6 tires. Plus... that Fireball Red and Kashima[emoji91][emoji91][emoji91]

Still sorting out my thoughts on the 2.6 DHF tires... the rear feels slow compared with the 2.4 DHR II on my previous bike.
I've got a 2.6 Rekon & Forekaster to test out on the rear over the next few rides.
Including dropping some weight, I think either of these tires will roll a fair bit faster than the DHF out back. I'll keep the DHF as a front tire for now.
I forgot to mention, the 21oz Camelbak water bottle fits in a Medium frame with X2 shock and Specialized Zee cage without problem. I remember reading somewhere people were unsure on the matter.

What size tires are you running and what is the internal diameter of those LB carbon hoops? Bike looks money!

Is this on the Ibis 742 wheels? What wheelset and internal diameter? Thx!

@Jason04, Recently l got to demo the Mach 6 and then the 5.5 for a very short time. I'm heading to demo an Ibis and possibly an Intense and Mondraker next weekend near Pisgah. Ibis seems to have the best customization for the price than Pivot so l'm anxious to compare the ride of the HD4/Mojo 3.
For a bike that's playful with moderate travel here in central NC would you still recommend the Ibis? I'm looking at the HD4 GX build with DPX2 and Fox 36 Factory but the dealer (4hours away) suggested DVO.

I think you'll have a lot of answers after your Ibis demo next weekend! If your priority is a "playful" bike than I'd look to the Mojo3 or Santa Cruz 5010. They're both incredibly playful but on longer and more harsh descents they get worked. Rear shock heats up and begins to feel dead and loose stability at mach chicken speeds.
If you're interested in a longer travel 27.5 bike the HD4 is as stable and composed as any in the category while still having a poppy and playful feel to it. I put over 40 miles on a Santa Cruz Bronson this week and the HD4 feels as playful or more so than the Bronson. More stable at speed and overall better grip and cornering.
Each bike has their own personality... you just need to demo and find the one that speaks to you! For me, the Ibis is everything I was looking for in a long travel 27.5 bike! Good luck!
I ordered an HD4 frame and will be building it up as soon as it gets here. I'm upgrading from an M3, and am wondering if anyone can confirm if the HD4 chainline is better with a boost or non-boost chainring? My M3 chainline was much more centered running a non-boost ring, even though it was a boost frame.

I also came from an m3 and i just reused my non boost oval on the hd4 without issues.

I carried over my 28T, non-boost round ring from a T275 onto this HD4. Works great but I would guess anything bigger than a 30T would not clear the CS.

Don't think hd4 is limited to a 30t, should be able to go bigger. The pros dont run 30t, they push bigger gears.

As stated in the post that's for a non boost chainring. A boost chainring will accomodate much larger thanks to sitting further away from the chainstay.
