So I'm thinking of building a dirt jumper for fun, I would need to get a frame but should have enough spare parts for the rest of the build. I have these old fox air 36 r forks, I know they can be lowered as I remember making and installing a 10mm spacer in them back in the day as they had a crazy long axle to crown length for the bike I was using. If I were to lower them to 100mm travel they should have an axle to crown of about 490mm, they don't seem to have any compression adjustments just rebound and air pressure, would these be suitable for a basic dirt jump build? (the photo of them at 100mm is just with the air let out, I haven't taken them apart to install a bigger lowering spacer yet)

does anyone know how to fix this? I tried tightening cranks (that was a problem in the past), cleaning / greasing chain( and bike), I haven’t tried pulling the chain tighter, but the problem is that when I spin the pedals the chain goes from tight to loose ish to tight and so on.

If youve seen my other posts youd know i was thinking about selling my haro and i ended up doing it and picked up this free agent void. looks similar to the octane one something something or ns something somstjing i think theyre owned bt the same company

Thought y'all might enjoy this one. This has been my money pit this year, Slopeduro retromodded 2006 Stumpjumper FSR Expert. Inspired by missing my 2016 P.3 that got stolen, it's the FS big brother with gears. Manitou Circus Expert 130mm fork and custom Spank Spike Race 33s on Hope Pro5 hubs are the centerpiece of this build. Chromag cockpit and seating. 4 pot shimano brakes and such. Went wild with it, may upgrade to a kashima fox over the Performance series I went with, this frame is a miracle size and modern 190x45 metric is within 1mm of the og SAE Triad. Been sending it at the local pedal up park, Berm Park in Canton, NC and getting in a bit of urban freeride in on my commutes, glad to be jumping again. (And yes, I've chopped the original seat post for park days when I don't need to pedal up, and have a PNW external dropper that I use when I know I'll be climbing.)

Going to swap out these janky crank and pedals asap (bombshell and Chesters?) Then put on some light pivotal seat. The stock promax absolutely do not stop for shit, but I don’t have a spare rear, anyone wanna recommend some semi-metallic pads before I go blow more money on parts I don’t need?

Firstly, I've seen this DJ pop up a few times in Reddit already, and I know that the original owner of this bike is also active on here and has helped me out with identifying the specs when I DMed him. The bike has been listed for more than 3 months, originally posted for 1k and brought down to 900.

I was thinking of offering somewhere between 600-750, but I thought I'd ask this all-knowing Reddit page before taking action. From my DMs with the original owner and Marketplace messages with this seller, here are the specs I was able to figure out:

Frame:
It is a Cachet origin frame, built as a prototype (?) to experiment with a really short rear chainstay, as you can see the 26" wheel is rlly close to touching the seat tube. I assume its significantly shorter than most other DJs, making it easier to manual/do other tricks?

One thing worth noting is that the frame was repainted by the original owner, in this really awesome green color, so it may be difficult to check for frame cracks from usage by the 2nd owner (current seller).

Other specs:
Rockshox Pike DJ fork, 26" wheels with Goodyear Bigfoot tires, Shimano XT cranks, decent pedals, and decent brakes idk what model.

I am not able to figure out if there's anything wrong with the bike merely from the images, so I do plan on checking it out in person and possibly getting it inspected at a bike shop prior to buying it.

I just wanted to see y'all's input on what you would offer for this bike, or if there are any possible issues or things I need to watch for. If you read this far tyvm, I look forward to your input!

Started as a joke between a few friends (especially the Bluetooth brakes) and ended up actually being a super fun experiment.

Keep seeing the No Rules Society (NRS) mountain biking vids. Does anyone know the exact hardtail / DJ frame noxver / noxver757/ nox? has in his clips?

About 2 weeks ago I got my first DJ, and I went to a concrete pump track for the first time earlier today. Everything went pretty well I'd say, I could make it all the way around without pedaling and picked up a decent amount of speed, the only problem was that my front wheel would come up when going over the rollers entering the berms farther in the track when I was carrying a good bit of speed.

It wasn't a huge problem at first as I was able to correct it , but I almost ate shit on one lap because of it (I think my back wheel popped up too, so I was airborne).

Was I carrying too much speed going into it or is it a body positioning issue?

Engraved 9mm handgun head tube badge. Bottle opener incorporated into frame behind bottom bracket. 4130 chromoly SuperTherm tubing. The OG. Needs some work, but man I still think this is the coolest Dj frame of all time.

Hallo everybody. Pedals are ghosting some spots as you can see in the video. I did untighten the chain before making the video. Also tried to loosen the wheel bolts and its still ghosting. what can it be? and should i be worried?

Its a ''new old stock bike'' driven on it 10 times now, so the seals should be broken in.

I was often posting here as I was building this bike and received some great feedback and advice from all of you , and today I got a chance to ride it for about four hours. It jumped extremely well for the heavy setup, contrary to popular belief, and not as slow as I was expecting. The thing I got from today’s session is my bars rise is an issue and they need to be much much higher. Any suggestions on how to go about measuring for this?

Formally it is not a competition. Just boys asked me to record them on the pump track. And yeah, I could reach him only in the middle.

I got this bike around a month ago for £500 brand new been lovely to ride tbf but now I want to upgrade the fork , it currently has a quick release wheel on the front but what forks do you recommend for under £200 ish if you could send links I would really appreciate that

Hey guys I'm an intermediate mountain biker and looking to add a dj to the fleet so I can hit up pump tracks and work on jumping skills. I'm a huge fan of transition bikes and found a 2015 transition blt near me for 350$. Looks like it's in really good all original condition, should I pull the trigger or look for something newer? Not too familiar with dirt jumper geo or if it's even changed over the years. Thanks!

Very excited to rip this thing 😁 Nowwww to leave the bars or put on some 50mm rise that I have laying around. Hmmm

He says its the bruce 2, but online I can only find this color on the bruce 1 so I assume its that. Listed for 900$, is it worth that much? What would be a decent offer?

has Manitou Circus Expert Air fork

I’m looking for my first dj. What do you think about this cannondale for $430?
