About time the HD4 gets it's own Pic and Build thread! Mods, can you stick this one?

No it's the Fit 4, I could have just gotten the stock Fox 36 Performance but they threw the fork in for free. Fit 4 works great, probably to much fork for my riding/skill level but I'm not complaining. When I used the Fox recommended settings (102 psi, 2 turns out from full closed rebound) the front end felt like I was riding a jack-hammer, I took some air out and backed off the rebound and it feels buttery smooth now. I leave the HSC/LSC open, not sure those settings add to much for how I ride, which might be fast for someone 61 but slow for someone in their 20's or 30's.

Very late to the party and with the release of the newer model I was able to score a good deal on the HD4 at my LBS. I went with the base NX model but plan to swap some items from my Bronson v1. How do most folks feel about the Sram Level brakes? I currenty have the shimano XT's and have been very satisfied with them. I'll be swapping to the Easton Haven 35mm bar and stem. Any recommendations on platform pedals?

I have both the 2019 X2 and DPX2 for my HD4. I initially had trouble with the X2 (seals) but since the warranty rebuild the shock has been excellent. I use the DPX2 as a backup and was using it while the X2 was being rebuilt. The DPX2 is a good shock for trail and/or flow type riding but the X2 was more supportive and controlled (for rough/gravity oriented trails) once I got it dialed in. It did take some time to get it sorted and I am glad I didn't give up on it. It is an excellent shock. I have heard the DVO Topaz performs well too.

I'm very late to this party but noticing I can get a very good deal on a HD4 right now. I've been on a Mojo3 for the past 3 1/2 years and have absolutely loved it. Considering the jump to a bigger bike, as I have a single speed that I ride for the tame stuff.

Can anyone comment on a move from a Mojo3 to a HD4, pros and cons? I ride mostly rocky and some sandy trails, some quite technical and steep, others buff and smooth.

Any info would be appreciated.

Thanks!

I have a good amount of saddle time on both and own an HD4 (Mojo 3 is my father-in-laws). The 3 is way more fun on tame trails. It's more poppy, easier to manual, and is more responsive when riding slow(ish). It's also a more efficient climber. In short, I prefer the Mojo 3 in flow trails and just general trail riding.

The HD4 is kinda dull until you really open it up on the descents. There are far better climbers out there than the HD4, so if general trail riding is your game, I would suggest you look elsewhere. That being said, I live for the descents. I earn my climbs but I certainly don't like them. But when the trail points down whoa buddy it's time to party! I personally enjoy playful lines rather than the fastest lines and I demo'd a ton of bikes before pulling the trigger on the HD4.

Now as far as sizing goes, I have really really long legs and a very small torso with not a lot of reach. After owning the HD4 for some time, the three things I wish were different is, a steeper seat tube, a slightly longer front center to compensate for the steeper seat tube, and a reduced offset fork - all of which were addressed with the HD5.

I came from an HDR to the HD4. I disagree that the HD4 is dull on anything other than descents. I have not found this to be the case at all. The HD4 climbs as good if not better than the HDR. I originally considered keeping the HDR for long backcountry rides. My wife's friend really wanted to buy it so I sold it to her. I have no problem with the HD4 on backcountry rides. The HD4 is an excellent all around trail/enduro bike. If you have out of the norm proportions (e.g. long legs, short torso), then may you should consider different geometries, different bikes. Otherwise, tweaks can be made to stack height, handlebar sweep/rise, etc.

I'll split the difference. I had a SC 5010, a med, and loved the the way I could flick it through the tight stuff, but also like how well it climbed the technical stuff. However I tend to ride alone, and on some of the big drops I thought I could benefit from a little slacker geometry, so I picked up a large HD4.

Where you could accelerate the 5010 over many obstacles on the climbs, I did better slowing down and grinding on the HD4. And where the 5010 felt fast on the singletrack, the HD4 didn't.

However when I compared my lap times, the HD4 was always faster, if only by seconds. I first I couldn't believe it, but the numbers don't lie.So, I kinda understand ABQ feelings.
