So in the town i live in unfortunately the biking culture in general is very undeveloped and there is no experienced bike shops here so oneday i noticed that my tyres were flat and i brought it to a bike shop to patch them up or replace the inner tubes because i ran out of patches. Then the guy patched up the front tyre all good and when it came to the back tyre the presta valve on the inner tube was broken and needed a new inner tube. the guy only had schrader inner tubes so he literally drilled my rim to fit the schrader valved inner tube. i was in a hurry and had to get on my bike fast at the time (this happened maybe more than a year ago and i didn’t know as much about bikes either) now i regret it so much because having to use schrader on my back tyre and presta on the front is very inconvenient because i have to change the nozzle of my pump every time in between pumping front and back tyres. also it just looks weird and schrader valve is much harder to use. is there a way of reverting this? i’m also scared of the possibility of rim cracking due to the fact that its been drilled.

there are [spacers](https://www.perennialcycle.com/schrader-to-presta-valve-rim-adapter.html?utm_source=google&utm_medium=cpc&utm_campaign=%5BCB%5D%20Google%20Shopping%20Ads%20-%20Jan%202020%20Onwards&gclid=Cj0KCQiAnfmsBhDfARIsAM7MKi1wi11Hx1z-eV7oSzz1viHESbAruE5TBxVe_MFdcQG8AFJXiO84bqgaAk7vEALw_wcB)
I wouldn’t worry about the integrity of the rim
I bought a set of Presta rims once – by mistake – and considered doing that. After a minute of thought, I bought Presta tubes.
Convert your wheels to tubeless and use a Schrader tubeless valve, maybe even convert the other one to Schrader if symmetry bothers you. Schrader valves really aren’t bad we use them for plenty of things like cars already. Most bike pumps already have both styles of valve.
They should be replacing that wheel free of charge.
But also, you can just get a spacer. Just look up [Presta Grommet](https://www.universalcycles.com/shopping/product_details.php?id=7716)
WHY in hellz dont folks say the name of the places that do this shit…
You can put a schrader valve adapter on your presta valve so you don’t have to change pump heads.
I did this to my own beaten up bike because I only had a schrader. Outrageous from a bike shop!
Edit: outrages -> outrageous
I did this on a set of wheels after ordering presta by mistake. I’ve put hundreds of miles both on and off road on them with zero issues.
Id ask for a free presta grommet when you go back. Not calling to ask if this was okay is simple bafoonery and terrible business
You really took your bike to the shop to change an inner tube? Surely that took more energy than just changing it yourself?
You can use a valve spacer or nuts to use presta valve. On other note, drilling to fit a schrader valve is normal and safe for aluminium wheels.

Yeah this should only be done at customer request, I’d bring it up and ask what they can do for you, if you’re really not happy about this then I’d press for a new wheel
Did you tell them someone screwed up your wheel? If that wasn’t the owner they will want to know and if it was they should be doxxed
I don’t get it. Why are schrader valves so hated??
I had a big gap in my MTB’ing, and went from a time where schraders were everywhere to now, with presta are everywhere.
I’ll take schrader any day! They just work so much better.
Wow. I was asked by a customer to drill his rims to fit the new tubes he bought. Both the shop owner and I said “absolutely not” at the same time. Not ever would I do that in a shop.
I’d personally be demanding new rims, regardless of whether they were compromised structurally or not.
You took a bike to a bike shop to change an inner tube.. you might as well just throw money away.. it’s the most basic of bike maintenance..
I did this on a set of sun ringle MTB rims and then used them on a jump bike with no issues. I do wish I didn’t but that was the only ill effect.
Your wheel will probably be fine. A friend of mine is a low-key pioneer and influencer in mountain biking, and he has or had done this to every pair of wheels he ever bolted on a bicycle. He did this because Schrader valves are just more durable.
You can still fit a presta back there and tighten with the ring. It wont be as flush but still
If the one tire presta one tire schrader is making it annoying to pump there are floor pumps with holes for both valves on the nozzle so you can just put the valve in the appropriate hole and pump away without having to fiddle with adapters.
You can just get rubber rings that will stop a oresta from rattling around in them some DT swiss rims come with them as standard
Eh, that’s totally fine on such a beefy rim. Honestly, I’d just drill the other one too, or get the shop to do it. Schraeder are sturdier and you can fill them up at the gas station!
