Bearded Midget Posted June 4, 2008 Report Share Posted June 4, 2008 (edited) just asking for some advice from people who have done this. what size file did you use to file your rims to sqaures/rectangles? also, have any of you cracked them in the corners yet? im mainly a natural/comp rider so i dont bash my bike up on the street much so im hoping they will last me at least half a year. did any of you find out how much weight you saved? cheerz, Reece Edited June 4, 2008 by Bearded Midget Quote Link to comment Share on other sites More sharing options...
forteh Posted June 4, 2008 Report Share Posted June 4, 2008 It would be far better to machine them out with a dremel and some carbide cutters/burrs, will take the material out faster and allow you to easily leave rounded corners rather that square ones which will just propogate cracks Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted June 4, 2008 Report Share Posted June 4, 2008 im mainly a natural/comp rider so i dont bash my bike up on the street much so im hoping they will last me at least half a year. I've not heard of many of the squared out rims failing due to cracking, but obviously that's not to say it hasn't happened by a long shot. However, if you're a fairly smooth natural/comp rider then for a fairly normal rim (not DOB etc) they should last you six months fairly easily Is that all you honestly expect from a rim? I always expect them to last longer than that, but maybe it's because I'm too cheap to keep buying kit Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted June 4, 2008 Report Share Posted June 4, 2008 i just used whatever size fitted perfectly in the whole, its f**king hard work matey, took me like 8 hours overall, although that wasnt straight, next time i would try the dremel method Quote Link to comment Share on other sites More sharing options...
walker Posted June 4, 2008 Report Share Posted June 4, 2008 if you make yourself a template out of plastic of the hole you want, you'll be able to draw round it and get each one the same as the last. Not something ive done, but it sounds logical. Andrew Quote Link to comment Share on other sites More sharing options...

kid creole Posted June 4, 2008 Report Share Posted June 4, 2008 i was gonna do this reece but couldnt be bothered in the end, I think Inur said it only saves around 50g per wheel Quote Link to comment Share on other sites More sharing options...
Bearded Midget Posted June 4, 2008 Author Report Share Posted June 4, 2008 i was gonna do this reece but couldnt be bothered in the end, I think Inur said it only saves around 50g per wheel might just drill them like you did then al. wouldnt take half as long, and would still save a little bit of weight. i did my tyres today, took off every other tread around the outside of the tyres. saved 80grams Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted June 4, 2008 Report Share Posted June 4, 2008 Weight saving freaks. Its a matter of grams what's the point? If maybe all the little weight saving changes from a 10kg bike, to get it to 9kg, but structurely it was fine then it might be worth it. But for the sake of 500g and a weaker bike its hardly worth it. Quote Link to comment Share on other sites More sharing options...
basher Posted June 4, 2008 Report Share Posted June 4, 2008 It depends what rims you do it on to how long they will last really and also how big you do them. If you do it on a echo rim youll be fine. I wouldnt do it on a DOB rim. On a tryall i wouldn't go to big with the squares just abit biiger than the circle. If your doing it with a file use a jigsaw to make a ruff square first.

Ahh but thanks to physics - rotating weight becomes more important... ie - save 50 grams on your rear wheel >>> saving 50grams on your frame.

TrAsHeR Posted June 4, 2008 Report Share Posted June 4, 2008 Hey Reece I filed my rim took me f**king ages about 15-20 min for each when your used to it. I used a big file and a smaller one. It isn't hard to keep them to same just go out to the side of each circles. Saves a bit of weight and looks good. Anyway got you some pics: Quote Link to comment Share on other sites More sharing options...
Bearded Midget Posted June 4, 2008 Author Report Share Posted June 4, 2008 (edited) where can i buy files lol, i assume b and q will have several instore? Edited June 4, 2008 by Bearded Midget Quote Link to comment Share on other sites More sharing options...
TrAsHeR Posted June 4, 2008 Report Share Posted June 4, 2008 where can i buy files lol, i assume b and q will have several instore? B&Q will. Or next ride I see you I could lend them to you. As I don't need them, and also the big one is just the same wit. Quote Link to comment Share on other sites More sharing options...
Dave Anscombe Posted June 4, 2008 Report Share Posted June 4, 2008 I done this a year or so back......only on the front mind you.......like ash said a file that will fit. its seriously hard work and my hands hurt and cramped for a day or two....light as hell and lasted me ummm 8 months or somthing......i only expect rear rim to last no longer than 6 months But good luck and post up some pics when they are finished Dave x ohhh yeah most hardwear stores will have all sizes of files Quote Link to comment Share on other sites More sharing options...

But for the sake of 500g and a weaker bike its hardly worth it. But it all starts to add up these 20grams here and there and then eventually you can feel the difference and if your a comp rider then its make a hell of a difference. You can be an amzing rider but if you get knackered in a section you cant use your talent to its full as your knackered. If your bike is lighter then throughing it around for 2minutes striaght becomes alot easier and means you dont get tired so easily and allows you rider to your best.

Alex-Mitchinson Posted June 4, 2008 Report Share Posted June 4, 2008 Go for it, thinking of doing mine soon. Don't bother drilling though, Muel did like 100 holes in his front rim and saved an amazing 24g's. Quote Link to comment Share on other sites More sharing options...
Gandalf the Yellow Posted June 4, 2008 Report Share Posted June 4, 2008 i got bored over the rainy bank holiday so i decided to give it a go.... done 8 holes and kind of got bored.... so i just left it for now, im going to have to give it a go another time... don't know about weight saving, but it sure looks freakin sweet. steve Quote Link to comment Share on other sites More sharing options...

Actually, it was 168 holes and 18g. Took about 2 hours/the piss. Quote Link to comment Share on other sites More sharing options...
Greetings Posted June 5, 2008 Report Share Posted June 5, 2008 Used a file and a hacksaw. Holes are 30mm wide and 25mm long. The rim is a BT (same as TryAll but eyeleted). It saved about 75g on the rear rim. This will weaken your rims a lot. But if you're a smooth rider it doesn't matter. Quote Link to comment Share on other sites More sharing options...

Shaun H Posted June 7, 2008 Report Share Posted June 7, 2008 Don't use a file. Buy a nasty looking rasp and it'll cut the time in half. SRSLY. (rasps are like really aggressive files for use on aluminium, they're bad ass) Quote Link to comment Share on other sites More sharing options...
Alex-Mitchinson Posted June 7, 2008 Report Share Posted June 7, 2008 Can't you use Rasp's to give a similar affect to ginding your rim as well? Quote Link to comment Share on other sites More sharing options...
