Valve hole on rims too small...

Hi guys, The valve hole on my rims are too small to fit a schrader valve through.
The rims are Alex SX44's...
Would I be ok with drilling the hole big enough to fit schraders aslong as I smooth the edges where I've drilled?
Cheers for any info.

Looks like its just the wall on the inside of the rim that's too small, It fits through the outside hole...0

Use a presta tube?0

Bolllocks, it'll be fine.0 -
Is the rim strip offset? And are they designed to be used with schrader valves?DanDax1990 wrote:Looks like its just the wall on the inside of the rim that's too small, It fits through the outside hole...
TBH, I wouldn't drill them, use presta valves.A much loved, Giant Trance X3 20100 -

Are you for real? You'd rather get the drill out then spend £4 on a new tube!? Bonkers."Why have that extra tooth if you're not using it?" - Brian Lopes

Just get a small needle file and file the holes bigger. Jobs a gud un.0

Not got a clue what you mean about the rim strip lol, I'm a Noob.
All I know is they're double walled and the outside wall is big enough but the inside isn't...
If there's a chance it'll weaken the rim then its a no no cause I'm a massive heffer as it is lol.
Only reason I wanna be able to use schraders is because it'd save me having to buy new prestas for new tyres... Got loads of spare schraders... Plus schraders are easier.0 -
Just use the inner tube that fits. It is beyond me why somebody would unnecessarily want to have to modify a wheel just to fit a type of tube you already have in the house when tubes are cheap enough to buy anyway.
Right tools/equipment for the job and all that...... Schraders easier??? how so?0 -
Been told that the little pin/nipple on prestas bend easily and if they do they're no good to use?0
-
It won't weaken the rim, you'll be absolutely fine. Done it dozens of times.
Saying that, presta tubes aren't a significant disadvantage either, they don't bend unless you're ham fisted. They don't fill with mud and it's easier to let air out of them.0 -

What he said0 -
Only asking if its ok to do because its a quick fix and can out my new tyres on sooner rather than later, I don't drive so can't get to lbs for the tubes I need today...
P.S I'm ham fisted lol, More like a sledge hammer lol0 -
Then yes, you can drill your rims out.0

8.5mm drill bit.
But if the hole would cut into the sides rather than he centre flat I would not do it."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Go to the lbs before ou start changin things over? Btw you do know you don't change te tube over when fitting new tyres right? So u sure why you need new tubes?0

I've got some Schwalbe City Jet's to fit, 26 x 1.95 and my current tyres are Maxxis High Rollers at 26 x 2.35 so was thinking the innertubes that're there for the Maxxis will be too big for my Schwalbes?
I've got some Schrader tubes at 1.5 - 2.2 for the City Jets and the only prestas I have ar 2.10 - 2.50 which are the ones I've got in now...
So need to change to smaller tubes?0 -
And yeah nicklouse, I wasn't gonna if it was going to go into the side wall...0
-
The bigger inner tubes will be fine too, they'll fit.0
-
i'd be trying them with the current tubes before spending anything tbh

Them ones should work ok tbf, and with them not being stretched as much could offer a bit more puncture resistance0 -
An 8.5mm bit (bet you don't have one) will cost more than the right tube!
I have drilled out rims before, do it slowly or the bit can screw through making it hard to get a clean hole, deburr it afterwards, but for decent rims I'd just get be tubes.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -
Still makes no sense at all though! May need new tubes for valve hole size........ricardo_smooth wrote:cooldad wrote:You start on the sauce early? i'll try again with properly strung words eh!

If you read the whole threa it does ;-) he talks about changing the tubes because he is changing the tyres over and that he has spare schrader tubes in the house and doesn't want to go buy some presta as he would have to walk there as he has no other mode of transport.
If it doesn't make sense now (after you re-read the thread)....you're stooopid 0 -
Did you also stoopidly miss the fact the new tyres are much thinner and that therefor the current tubes may be too big for them?Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

No, but you stoopidly missed that the OP gave that information AFTER I had posted that original replyThe Beginner wrote:Did you also stoopidly miss the fact the new tyres are much thinner and that therefor the current tubes may be too big for them?
