isitafox Posted October 18, 2011 Report Share Posted October 18, 2011 (edited) Well I finally got round to single walling my wheel last night so thought id take a few pics for anyone who wants to have a go themselves but is a bit unsure. My rim is a trialtech sport circle, tartybikes weighs it in at 708g so I was hoping to get it down to around the 620ish mark which is what the single wall sl rim weighs. I started by removing the tyre, tube and rimtape then refitting the wheel into the frame. I then turned the bike over so it was sturdy and started to cut between the holes with a thin metal cutting disc so I could judge where the internal web that strengthens the rim was positioned. Once I'd got the middle out I set to work with the same disc trimming the remaining lip as close to the web as possible trying not to damage it and kill the wheels strength completely. I held it at a slight angle to make life easier when I had to file the sharp edges after. I did the right side first so I could easily see where I was cutting then turned the wheel over to do the other side. Once both sides were trimmed back I went around the cut edges with a file to smooth them off and stop the tube from popping. Make sure to spend some time doing this and get all the rough and sharp edges taken off. Once this was done I brushed the rim off internally and just refitted the tape, tube and tyre, job done! Finally to justify my hard work I weighed the offcuts (would have been better to weigh the wheel before and after really but I haven't got any scales at work!) and found I'd saved at least 100g putting the wheel slightly below the sl's weight, result!

weirdoku Posted October 18, 2011 Report Share Posted October 18, 2011 I gotta ask, was it worth all that effort to save 88 grams? Quote Link to comment Share on other sites More sharing options...

isitafox Posted October 18, 2011 Author Report Share Posted October 18, 2011 (edited) I gotta ask, was it worth all that effort to save 88 grams? Yes as ive saved over 88g, at least 100g which makes it a lighter wheel than with an sl rim and getting tyres on is an absolute nightmare normally but now its easy. Plus it kept me busy for a few hours which id otherwise have spent sat lazing about doing nothing anyway. did you do this in work? You knows it dude Nice, neat job dude! Cheers Ads!

Mark W Posted October 18, 2011 Report Share Posted October 18, 2011 More volume in your tyre now too, which is a sort of additional bonus. Quote Link to comment Share on other sites More sharing options...
MiuSliS Posted October 18, 2011 Report Share Posted October 18, 2011 Did that to a 19" 07 echo rim. Threw it away after couple of weeks. But i guess it was the fact that it was couple years old by the time i did it. Quote Link to comment Share on other sites More sharing options...
forteh Posted October 18, 2011 Report Share Posted October 18, 2011 Nice neat job, if its for the front, open the holes out and you will save some more, got my dx32 down to 512g Quote Link to comment Share on other sites More sharing options...

Adam '93 Posted October 18, 2011 Report Share Posted October 18, 2011 Nicely done dude, makes me want to do it now. I imagine if you handled any type of tool you'd seriously injure yourself 1 Quote Link to comment Share on other sites More sharing options...
haydon_peter Posted October 18, 2011 Report Share Posted October 18, 2011 Yeah with a tiny bit of washing up liquid and some minor assistance. Was well hard getting it on properly, had it pumped to 50psi before i could get it set! Was bricking it expecting the pump to explode as its only a cheapo foot pump!!getting tyres on is an absolute nightmare normally but now its easy. Plus it kept me busy for a few hours which id otherwise have spent sat lazing about doing nothing anyway.So you need washing up liquid and a decent pump that can get it up to 50psi, it sounds really easy to get the tyre on After doing this do you need to run a wider rim tape to cover up the cut edge even though you have smoothed them off?

You haven't seen my footpump, was making some horrible creaking sounds as I got near 50psi and i've already nearly stripped the threads off the pressure gauge when it came off once before. No I just used the same rim tape and it's been fine, checked it earlier and it's still pumped up how I left it. Quote Link to comment Share on other sites More sharing options...
Rockman Posted October 19, 2011 Report Share Posted October 19, 2011 Would look real tidy if you filed the holes out so they were square as someone has said, making it lighter and look cooler. 1 Quote Link to comment Share on other sites More sharing options...

Azarathal Posted September 12, 2012 Report Share Posted September 12, 2012 Sorry for the graveyard bump but would it be easier to do with a dremel? I barely trust myself to grind my rims let alone grind the inner walls. If so, would anyone like to recommend a dremel for up to £30 inc shipping?

isitafox Posted September 12, 2012 Author Report Share Posted September 12, 2012 I'm pretty sure it'd take a looooong time with a dremel, the inner wall still took a bit of doing with a grinder. If your concerned then you could probably do it with a hacksaw. Quote Link to comment Share on other sites More sharing options...
Azarathal Posted September 12, 2012 Report Share Posted September 12, 2012 Wouldn't it be longer still with a hacksaw? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted September 12, 2012 Report Share Posted September 12, 2012 Dremel would take ages! I I used a hacksaw in the end to do mine as I broke my grinder, I seem to have this ability to break anything I touch. However a dremel with loads of attachments is brilliant for finishing and smoothing the rough edges to prevent punctures. But you can get away with wet and dry paper. Just depends if you want to get all sweaty. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted September 12, 2012 Report Share Posted September 12, 2012 I did one with a grinder and a file, took about an hour and is spot on. I've put a little extra tape on just to be on the safe side, but it was almost certainly a decent enough finish not to need it Quote Link to comment Share on other sites More sharing options...
Martin Reynolds Posted September 12, 2012 Report Share Posted September 12, 2012 My try-all rims completely tit'd, so might give it a practice on that Quote Link to comment Share on other sites More sharing options...
Azarathal Posted September 12, 2012 Report Share Posted September 12, 2012 So why would a dremel be so slow? I assumed they were meant for cutting things like this and it's only thin metal. I'll probably hacksaw it Quote Link to comment Share on other sites More sharing options...
Carlperkins Posted September 12, 2012 Report Share Posted September 12, 2012 Wouldn't it be longer still with a hacksaw? yes. but you can get a really thin diamond cutting disc for about £10 that fits into a drill. takes ahlf as much time as a hacksaw and not as intimidating as using a angle grinder. you may aswell just go for the angle grinder though, its easy. or are you not a power tool type of guy.
