Presta vs Schrader???

[Putty]

Hey wackwack, don't stress, rims are like girlfriends, you can drill them until their holes get bigger but they will still stay round. Just dont mess with their nipples cause it makes them buckle

[TNT1]

 

beats me that the Heavy's does not think twice about taking a drill to their bike frames !! Scary stuff .

 

Not that kind of heavy... look at that other thread, Delgado confirmed I only weigh like 25kgs

....if you drill your rims , is it still covered by warranty?

 

I prefer to stay away from my precious with any power tools

[scuzzy]

I must say, as far as I know, they drill it at the shop when you buy your new rims, don't they?

 

What I do know is that they do not mind doing for you, which means it is not a train smash.

 

But it will be interesting to know which one to go for, what do you use for tubeles, is that not the presta valve?  In which case you won't be able to do the conversion once you've decided which valve to cater for.

Or you could just buy yourself a pump like the one that I have where the presta and schrader thingy are both on the whatsit and you don't have to turn the little converter jobbie around....

shot, nancy, but that was not the OP's question...

[Nancy Drew]

that was in repsonse to #3 on his list bob - maybe I should've quoted

[wackwack]

I'm failing to see how drilling a slightly bigger hole in a rim can weaken it - given the fact it has 32 other holes drilled....

 

I think i'm gonna take the plunge & bring out the drill......

[Fleming]

I have seriously considered doing this aswell. Did it on my old Trek 7000 (Year 2000 Model) and the wheels are still fine.

[Johan Bornman]

Drilling a larger hole in the rim will technically weaken it but who cares? The weld is still the weakest point on the rim and that never breaks. Rims are under about 3 tons of compression, never tension, and a hole will have to be pretty big before it collapses under compression.

In catastrophic events where the wheel suffers a blow, it'll bend and often break too. The fact that it may break at the valve hole is not important, it'll be so badly bent in anyway, that it is a throw-away.

 

I used to be a Presta snob but with the advent of tubeless, I think Schrader makes a lot of sense.

And as for those who don't think power tools should not come near their bikes, dont be such sissies. Drilling only improves frames.

 

 

[scuzzy]

Ok, wait, I think I got something wrong here, is there a common valve for tubeless? or do you get it in both?

 

For some reason I was under the impression that the Presta is more common for Tubeless and was scared to drill the hole for when I do a conversion.

 

[Fleming]

I think Johan was refering to the ghetto tubeless conversion which requires a 20 inch BMX tube. 20 inch schrader tubes are available everywhere, where as 20 inch presta tubes are like hens teeth.

[KDEE]

20 inch Presta tubes available at shops that stock Bmx race bikes...

 

Its the Presta 20 with removable core that are a major prob to find..

 

[wackwack]

thanks for the input

[Tumbleweed]

so it's drill, baby, drill...
