Canned Posted August 17, 2005 Report Share Posted August 17, 2005 Ok - as per msg board etiquette I've already done the search! Found no answer to this though... Just questions on pros and cons of rim drilling. Does it reduce strength? Is the decrease in weight something that's going to make a difference at all levels or is it something that has no marked benefit at beginner/intermediate levels? Is the drilling itself best left to the pros? Does Rim tape prevent all movement of the tube through the drilling or does it allow some movement? If there is an amount of movement in the tube through the drilling does it affect how you set your tyre pressures? Am I asking too many questions!? :P Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 17, 2005 Report Share Posted August 17, 2005 If you're going to drill, don't fanny about. Little holes aren't going to save much weight, but are obviously going to reduce strength slightly. However, larger holes save more weight, without really reducing strength much more (it's more the fact there are actual holes in your rim that's the problem, not really the size, if you get me?). I got a front Try-All rim (drilled, obviously) and I had to adapt my technique for doing stuff 'cos I was sailing up stuff 'cos the front end was noticeably lighter. Saving weight in your wheel/tyre setup is one of the best places to do it, due to the fact that a lighter tyre means less rotational weight, plus on the back wheel, what's furthest forwards? Your front wheel. Therefore, if that's lighter, you're sound :) Standard rim tape won't be enough. However, electrical tape does the job. In my rear, I've got a rim tape surrounded by tape and it's fine. Front is just two Koxx rim strips that I got with the rim. Personally, I find it worth doing :P Quote Link to comment Share on other sites More sharing options...

Mark W Posted August 17, 2005 Report Share Posted August 17, 2005 Megamo used to sell them drilled, but called 'em their "Megamo Drilled Trials Rim". It's currently what's stopping my hub from scraping along the floor at the moment, and they're pretty sexy :P DX-32's are uber strong and only £23 too, so it's a bit of a bargain.

Sponge Posted August 17, 2005 Report Share Posted August 17, 2005 Certainly go for it! It looks nicer, but reduces only a bit of weight... and yes it does decrease strength, seeing as drilled rims are not recommended for unicycle trials, whereas non-drilled rims are... If people are so touchy about weight saving, then why not take loose change out or have a haircut and finger nails clipped more? :P Quote Link to comment Share on other sites More sharing options...
Janson Posted August 17, 2005 Report Share Posted August 17, 2005 dx32 are the shit. you can feel the flex in drilled rims, i am definitely going back to undrilled rear rims again. they look cleaner, less hassle with drilling etc, dont fill up with mud and water, only need 1 layer of electrical tape instead of a boatload of gaffer tape etc. drilled rims do not save -that- much weight really. superlight tubes is where it's at!

Janson Posted August 17, 2005 Report Share Posted August 17, 2005 yeah didnt think of the flex in mod wheels. i ran drilled dx32 and superlight tube. it is alright, but i'd really prefer an undrilled rim, mostly because it is practical.

*OnzaMike* Posted August 17, 2005 Report Share Posted August 17, 2005 Weight your loosing, your putting back on through rim tape? Just a thought? :P Quote Link to comment Share on other sites More sharing options...
Janson Posted August 17, 2005 Report Share Posted August 17, 2005 yeah, that's what i mean. an undrilled rim needs one strip of electrical tape, while a drilled needs several layers of electrical or gaffer tape = weiiiiiight. Quote Link to comment Share on other sites More sharing options...
chrishayton Posted August 17, 2005 Report Share Posted August 17, 2005 just get the koxx rim tape instead of electrical/gaffer, hardly weighs anything, and is hardley going to affect your riding Quote Link to comment Share on other sites More sharing options...
