Finally got the timing on this canopy drop in at the trails! Recorded on 03

I've been using my 3" 04 Pro cinewhoop to fly at these trails for the past year or so but this weekend I broke it on my first pack. I brought my 3.5" 03 cinewhoop along as backup. First I tried running a GoPro on it but after building the muscle memory flying these trails with a 250g quad it just wasn't happening. So I said fuck it and, even though I didn't have any ND filters for it, just went with the 03 footage.

Turned out pretty good IMO! Would have been even better if I hadn't forgotten I was on 2K and 120FPS all day. Whoops.

Budget build up of $40 FB find.

2010 Specialized P.1 with limited edition splatter paint. Found on FB for $40. Only kept Azonic Outlaw front wheel and handle bars, which appear to be original. Has RST Dirt fork for now. Waiting on Gusset DJ rigid fork to arrive. Other parts:

Specialized Stout Stem
Shimano MT200 rear brake
Techtro 160mm disc*
Bontrager lock on grips*
Odyssey integrated headset
Odyssey 19mm Euro BB
STLN Bikes 170mm ChroMo cranks
Fooker composite pedals*
Mission Nexus 25t sprocket
SRAM PC-1 chain
Novatec single speed rear wheel with 13t cog

*indicates items from my parts bin

Really happy with it. Frame cleaned up really nice and even with the crappy RST fork, it’s a great ride.

Found this Octane one void but idk if the head tube is tapered? Also do you think its worth it for 500?

New wheel doesn't fit

edit: I've realised im an idiot and I cant fit my rear cog on as I dont have spacers, and my old one was threaded, so I need to buy spacers. Sorry im new 😅

I bought a new alaudark wheel and my chainring doesn't fit as it doesn't have a driver with a thread and sits next to spokes, see photos for more.

What do you look for in a dirt jumper? (geometry specific)

With BMX every frame was nearly the same, and you would generally only make adjustments to cockpit to makes changes. So it was brain dead easy.

With MTB the numbers are so vastly different it makes it easy to invalidate 90% of the frames when you're looking for something, so you basically just pick price, build, and linkage.

But with dirt jumpers I've landed in between, the uncanny valley of 'all very similar, but generally different enough to change the feel'.

Are you looking for a zippy 380mm chainstay? Or a more stable 400mm?

Are you looking for longer reach bikes to seemingly scale with height? Or do you just buy short bikes no matter what knowing you want the bike to be nimble?

My GF just bought a Propain Trickshot and it's fairly tiny on me but I really do like how it feels, even if it feels twitchy on larger jumps.

Considering I am not spinning (or unlikely to) and not tail whipping, should I just look for a more stable 390-400mm RC rig? And maybe a longer reach and taller stack?

Orrr do you think the margins are so small with all dirt jumper bike it basically doesn't matter... Just treat them like BMX bikes and adjust the cockpit of whatever you can afford, etc.

Saracen CR2 chainring

Looking to buy this Saracen cr2 but it comes with 25t chainring. I like a heavier gear so looking to do 32/12 or minimum 30/12.

Do you think there is space to get 32t on this? Or 30t as a backup? Haven’t bought it yet and i can’t ask the guy to measure.

QR rear wheel on horizontal drop outs

I'm looking at a new DJ frame, but my current frame has a QR rear wheel and vertical dropouts (with a tensioner)

Can I use this wheel on a horizontal drop out frame?

Instead of a proper QR it has a skewer that tightens with an allen key but I think it's the same?

One of the sickest riding weekends ever. Went to a wedding near Temecula, decided to turn it into a bike park trip. 4 parks, 2 days

Full Face in Full Humidity

Will be permanently in Dallas in June, and need to start thinking about trading in my padded out 661 thats plenty suitable for the Asheville, NC climate, but might be a bit much for the Texas summer.....

What are your thoughts and experiences with a full that still offers great protection with a bit more ventilation?

And no, im not going with a half lid.... I cant afford to replace more teeth than I already have...

Folsom bike park opening

My 8 year old son hitting the first jump on the inter line.

I seen a bunch of kids on suspension bikes/DJs. Thoughts on upgrading his bike to a DJ or just keep him on his Bmx? Would it help him maintain his speed throughout the jumps upgrading to a DJ?

Is it worth putting any money into this to sell?

Made this from old parts

Norco one25 frame and some old magura forks

Have a juicy 5 rear brake for it

The rear hub bearings are worn out

Do i just sell this as is or put a bit of effort into it to sell it?

Not sure about the right sub for this cryptid: "VOIDERTINGER-05", 24" Octane One VOID w. FOX Air Factory Talas 160-120mm (made to shred on fun trails and fun pump tracks, hehe)

It's sooo much fun! :D
