Does anyone have, or know of, a photo of a wheel without the tyre? I am looking to do a diy tubeless conversion and would like to see a close up lateral cross section of the rim before I start the process (preferably shown with an adjacent measuring device, such as a rule)

Thanks in advance

Just curious, what tires are you planning on running tubeless on it?
At the moment I plan on using the oem tyres untill such time as they need replacing. At which time I will seek further guidance from you good folks! My riding is basically on paved surfaces and I have a TPMS

It might be worth tracking down a tubeless type tire that you want to run before making the conversion. It would stink to put the time and money into it and then find out either that air permeates the stock tire, or a small bump to the sidewall lets it out. Tubeless tires run fine with a tube in them, but tube tyres without a tube are a gamble.

I cant see the point in this at all. what's the benefit? get off road tubes that have the auto seal stuff in them, makes a huge difference if there's a puncture.. if that's what you are trying to accomplish. also keep in mind, when the rim needs to be trued or spokes tightened, if you seal it up, that will all need to be redone at the time. I've seen this done on a few ahrma race bikes and is always a pain in the ass down the road.

Thanks for that input - I did a bit of research on tyre porosity but actual experience is sketchy on-line. I have however talked with my tyre fitter and he is researching suitable tubeless tyres that may be available here in the UK. As you indirectly suggest, putting the tube back in after the conversion might give the best of both worlds as the unsprung extra weight of tape+sealant is small. The actual process seems simple enough, inexpensive and retirement time is there to be used!

This is the scheme I will follow:-

Thanks for your thoughts and I have to agree with about the sealant. I used to use it on my big road bikes and it proved its value a couple of times:-



but I then moved on to the externally applied mushroom system as I found I was repairing punctures for fellow riders as well! However I have never had success with sealant on my offroad SP370 trail bike with it’s tubed tyres and the consequent inconvenience of a puncture when out on the mountain forest roads near us

I will be checking spoke tension before applying the nipple sealant and tape and should I subsequently have to return to a specific area I think that could be cut out and a new “patch” applied after attending to the spoke

yeah. sealing a leak at a sealed spoke is much worse IMHO than replacing a tube. but to each their own i guess. 🤷‍♂️
