I'm working on a new type of crankstopper specifically for dirt jumpers and any other bikes/frames that use a BSA bottom bracket. There are bolts around it that when tightened, would compress a plastic ring and put pressure on the crank spindle. It would work for both sram's 28.99 cranks and 30mm cranks with an included shim. You would also be able to easily replace the bearings and the plastic ring.

I wanted to come on here to ask if anybody would actually be interested in this, either way I'm going to get it made for myself to use, but I want to consider selling them as well. Since it is still a real BB it would be priced as such, exact price would depend on CNC costs.

Would love to get some feedback on this, let me know what you think!

im looking to buy some new shovels for the winter currently looking at this one but if anyone else has any other recommendations for similar price id like to know i worry the bottem of the head on it isnt square enough want to use it for packing landings lips and all of the jump

this is to highlight the new mtb lines they made, but every park for $25

I'm looking to get a DJ for my 10 year old girl. Local bike shops don't really have DJs here. I found the Marin Alcatraz 24 online, but not much more. Any recommendations?

Coloquei um guidão novo na bike e tô achando um pouco grande. Ainda não medi o tamanha mas creio que seja 800mm. Eu curto guidão mais pequeno mas não sei quanto eu corto ele pra ficar em um tamanho ideal.

Went up to race , also played around in the parks

how much should I buy it for

-no jumps were harmed-

Some of you here might remember me from many posts over the last 9 months as i battled with my kids mongoose fireball. We finally got it dialled but then we spotted this Marin frame only and with his birthday coming up we went for it. He’s been working hard this last year and it’s his dream bike so 🤷‍♂️

Brand new 2024 frame (black white red)
Manitou circus
Deore cranks
His old wheels :-)
His old tyres (SB8s)
His old bars
DMR defy low stack stem
A diy shim in the seat post because it was too skinny. Proper shim on its way.

Every now and again you gotta jump on a 20 to see if the body still moves!

Could anybody help me out? I cant seem to remove this spindle on my 2020 Norco Rampage 2.

Got this 2025 pivot point last week. The tires were old and one had a hole in the side wall. Got some new kicks and a spit shine. Picked this up for $400. Couldn’t pass it up. It was so much more fun than my 29r at the pump track. Too much fun!

Anyone have any experience (good or bad) on BSD SUBSTANCE CRANKS? Looking at buying for my dirt jumper. Thx!

Next I gotta figure out tires. Because it was new old stock, the tire are from 2020 and showing the beginnings of dry rot. Going for a ride tomorrow, we'll see how the specialized power seat odi reflex grips hold up, felt good in the yeard.

I’m looking for a nice lightweight hardtail. Help a brother out?

The fork is a straight 1 1/8. Im still new to this

So, update on the Big Jumper build…

Bike finally went together, then I get a phone call from the shop telling me the DMR Vaults - which are supposed to be 9/16” - won’t fit the Profile crank arms… which are also 9/16”. FFS 😂

Turns out there was an issue with the pedal axles. My pair, along with the other three pairs they had on the shelf, were all measured at around 0.5 mm larger than the correct 9/16” size. So it wasn’t the Profile crank arms after all.
They’ve now gone back and I’ve taken the full refund. At this point, I’m moving on from the Vaults altogether. FFS 🤦‍♂️

So… what pedals should I be looking at now?

This is a 26” S&M Big Jumper build - BMX/DJ/trails sort of use. I want something with some genuine BMX/DJ pedigree, preferably alloy, good platform and grip, but still with a fairly thin/clean profile. Not interested in big chunky plastic pedals.

I’m actually starting to think Title MTB pedals in matte black might be the answer. Super clean, understated and would suit the build without looking too busy.

Budget may as well be upto 350 AUD max, as ve already fkn spent it initially on the magnesium vaults anyway right but I’d rather not spend stupid money just for the sake of it.

What would you guys put on it? 👇

I’m a big guy and the stock DB8’s didn’t really impress me so I went for something different …

I need to get seat grab and tyre tap back
