7 exactly same blowouts in 7 tubes in 2 weeks

Glad to hear your tube problems have abated for now, but it's always worrisome when I see presta rims drilled for Schrader valves.

technically do you know why this could create problems? I'm not that in tune with the mechanics of such things.

A narrower rim has enough material in it to make sure that it is safe for the forces it is subjected to. If you go and make a larger hole in that rim, it may/may not effect durability. I seriously doubt it will make a lot of difference, but I always err on the side of caution, as I'm a big guy. Also, I think narrower rims are made for presta tubes, which tend to run thinner. I like 700x23, all the way up to 700x28, but I run even 700x28s on a wider rim than that. Narrower valve-narrower rim, wider valve-wider rim. If I'm going for speed, I'm usually on 700x23s or 700x25s, with presta valves. If I'm touring, or have a load, or I'm worried about the state of roads, then I'm on 700x28s, which have rims for schraeder valves. I suppose it would depend on the state of the roads in Loovul, as well.

That's not good on the LBS's part, especially when they kept on supplying you with numerous numbers of tubes and not saying about drilling the rim, I myself would be asking them to supply you with a replacement rim that is the CORRECT one and pay for some reputable wheel builder to sort it and some decent inner tubes, I think if you confront them with all of that you may at least get some part in recompense....

unfortunately the mechanic that did the work is no longer there and the owner is not very reputable......live and learn

thanks for that info , it all makes perfect sense.

Schwalbe tubes come with a ring that centres Presta into Schraeder holes
