I assume most guys hanging around in this area knows pinkbike. So let's start a similar thread where you can ask a quick question, without having to make a whole 10 page thread talking rubbish.

[stewie911]

First up:

Are you guys running tubes for dirt jump or can we go tubeless? Snakebite being one of my biggest concerns.

If tubeless, what tyre pressures

[Super_mil]

I run tubes and have yet to puncture (touch wood). I do ride the odd trail on the bike too (normally with the hounds following )
I run my tyres really hard 55psi or 3.8bar
I've played around with the pressures from 40psi to 60psi and to be honest can't feel too much of a difference when jumping.

Actual tyres make a huge difference (obviously) to rolling resistance. The Specialized Rythms & Compounds (came stock) are by far the quickest tyres I've been on.

[stewie911]

Should I use downhill/jump spesific quick releases or can I use my normal xc wheel quick releases?

I don't think DH and Jump bikes use QR skewers. They use through axles that's at least 6mm bigger then normal ones.

[stewie911]

Usually, but I've got DMR wheels, which seems to fit qr skewers and they are jump wheels.

[Super_mil]

My OEM hubs have fixed axels and bolt onto the drop outs.
I'm pretty sure you can run standard hubs and skewers though. I hope so, since I have a new front wheel that will be going on in due coarse with a standard skewer.

When is that bike of yours going to be ready?
Your knee/shin guards are still waiting...

I don't do alot of jumping, but I would imagine that tubeless wouldn't be great due to the tire rolling on the rim and "burping"... Yes running your tires super hard would counter this, but then should you have a blow out, you going to blow the tire.

Much rather pop the tube and carry a spare - what say you guys out there?

[stewie911]

Only got the wheels yesterday. Still need a seatpost and a way to tension the chain.

Will have to make sure what the best way will be with the frame.

I have a singlespeed chain. Can I use that on a normal cassette? The bike will be singlespeed, but for now, I'll just use a normal cassette before I get spacers and stuff

[MoreTrails]

Hmmm, probably won't fit - SS chain is too wide. You make up spacers really easy using plastic pipe cut to the right length, otherwise a DMR single speed conversion kit is the way to go, I've had mine for years and its still going strong

[stewie911]

Ok, so I the chain will fit easy with a makeshift spacer set and normal casette ring

[mad bout mtb]

I used 2 run tubless but lost too muct sealent form the tire burping

[MoreTrails]

@ Mad bout mtb - Tires were being run too soft then...

@ Stewie911 - Then you are a-for-away. if you got spacers sorted, you could always use a loose cassette cog. Better still On One / Planet X SA website sell cogs for singlespeeds - or PM Kiwi, that dude will hook you up.

[PeterWest]

Are there any trial riders are tygervalley, durbanville area really want to learn stuff from some guys

[ridin dirty]

are all 20mm hubs the same length?

if i buy one new will it fit a diff fork other than my manitou?

[kosmonooit]

Is the cherry always on the top?
