Can anyone tell me where I can get some DH tubes with presta valves for a fair price? I don't really want to drill out my rims.
Thanks

i can sell you a drill bit for a fair price....
drill them, much cheaper, much more durable, much more convenient with tire guages
im with stupid, that lets you run both types just incaseTranscend said:
no dont drill, I got some Salsa tubes... 1.5mm thiick...?? somthing like that, really nice they even say moto on the box!!!!!!!!!!!
or you could run every other tube out there....KomodoRider said:
why do people want to hold on to presta so badly when they cant even find tubes for them?
either drill or get some new rims that will fit shrader valves.prestas should be keept to xc riders and racers not to dh. and when you drill the rim out get some irc tubes there fairly thick didnt get a good look. but the valves are reinforces with alluminum. now thats awsome so there is no more weak spot at the valve.
now thats cost effectivness at a maxme89 said:
I guess I will just take the plunge, anyone know what size I need to drill the hole?
just drill incrementally bigger holes. Alot easier to get a clean hole that way too.gierhed said:
or you could just compare the bit to the valve...
NO DON'T DRILL!
PRESTA IS LIGHTER!
THE RIM IS STRONGER WTIH IT!
tHERE are only disadvantages if you are a four assed monkey that can not spell dexterity!

Bah, I can sell him a DH MTB drill bit for an outragous price. It's a CK drill bit so it'll cost about $115 bucks...
If I take a blowtorch to it it may even come out "rasta"...
First rule of mountain biking business: "Why charge a fair price when you can charge WAY more than it's worth??!!"
Don't Drill!!!!

go tubeless, maxxis has presta rim strips for going tubeless, then you won't pinch flat, also get some stan"s sealant so it will hold air. regular maxxis tires work great. when choosing rim strips find the one that has the closest width and profile to your rim, for best results.
or drill, find a scrheader valve and compare it to some drill bits, something just larger will be perfect.

What kind of rims do you run? Most of the heavy duty DH tubes have schrader valves (for easier pumping at local gas station, etc).gierhed said:
If you have D321's or D521's, most D321/521's come with a priesta valve adaptor in where the valve inserts. You can pop out the priesta valve adaptor and you'll have a schrader valve hole. Just my $0.02.

yeah, i really want to save that 0.5 grams by using presta....oh wait, the rim hole is bigger so maybe its status quo.klunky said:
And just in case people are actually serious about thinking that a presta drilled rim is stronger than a shreader one, well, its not...
Good timing - I just decided to go back to tubes.
I did it to a new rim this weekend. Just get a round file and keep going until the thing fits. It's a little more work, but hey you'd have to file down the burrs anyway...right? Don't waste you time with the really fine grit files, get the one for re-sizing and shaping. Oh yea, I'm pretty happy with Hutchinson DH tubes too.gierhed said:
I run the Kenda tubes ( they also make the salsa DH tubes) with prestas and have had no problems. I have pinched the green hutchinson tubes ( evil greenies ).

if it's on a DH bike you may need to drill out the rims for the DH rimstrip...I can't remember...
tubes are soooo over brah...
Avenir makes a great DH tube for either valve for super cheap. But I would drill if I were you, that way in a pinch (no pun intended 
) you can run whatever's on hand, and not be limited. Perfect example; Downieville yesterday I pinched the rear, I had a presta DH tube in my 521 with rubber grommet, my buddy gave me a Maxxis DH Schrader tube and off we went...

Pinch flat at Downieville?!!? hard to believe!punkassean said:
although rocky up there, it's not half as bad as the SB trails I'm used to shuttling! I've learned to ride light on the rear end...
