NotSoBigBen Posted June 14, 2022 Share So I have another, probably stupid, idea to try out I have a single speed bike I only ride on the road ... it has alu 'deep' section standard road rims I've always just run with normal road tyres 700x25. So I'm scheming to get some 700x38's or thereabouts and run them tubeless with a ghetto conversion. Then run around 40psi or so Need longish valves so either long tubeless valves if I can get or something with a long valved tube? Anyway anyone tried something like that before?

Titleist Posted June 14, 2022 Share 80mm tubeless valves are available NotSoBigBen 1 Link to comment Share on other sites More sharing options...
shaper Posted June 14, 2022 Share You can get your LBS to order from Paragon, they do 80 and 100mm valves. I have a 100mm valve on my 88mm rear tri wheel. https://www.paragontech.co.za/product-category/wheel-parts-related/tubeless-valves/ NotSoBigBen 1 Link to comment Share on other sites More sharing options...
Lanoy Sports Posted June 14, 2022 Share then add in Orangeseal and you are good to go - it is the best for higher pressure uses like road or gravel. Link to comment Share on other sites More sharing options...

I have finally run out of that other brand, so keen to try this one. The 'regular' appears to have a better sealing action than the 'endurance' but doesn't last as long - am I understanding that correctly ? And then, how big are the bottles of sealant that you are selling ? It looks like the refill is a bit bigger than the one with the injector.

It looks like the refill is a bit bigger than the one with the injector. 100% correct. that said this stuff lasts really well. i run regular only in the gravel and road bikes and can go months never having to top up. one of the major upsides to this product over others is it does not cake into a ghostbusters style monster in your tire when drying up - ie you don't get a massive weight in on e section of tire where it dried out. it also peals off extremely easy for those worried about lugging around extra weight. MTB i do an initial fill with Regular and then on top up with Endurance. the smaller bottle with the injector is 236ml (8oz) the larger refill bottle is 473ml (16oz) MDJ and splat 2 Link to comment Share on other sites More sharing options...

What's the internal width of those rims? You'll need at least 17mm to run 38s, preferably closer to 20 or 21 though. Long tubeless valves are easy enough. 100Tours 1 Link to comment Share on other sites More sharing options...

Probably very narrow, not home to measure them ... anyway got some 'Chaoyong' 700x35's and 2 long valves so gonna give it a go anyway 😎 Link to comment Share on other sites More sharing options...

I'm in with non tubeless, not a bike I ride much, just fun! I have 2 other sets of MTB wheels running non tubeless tyres for an all purpose road (700x38) and gravel (29×1.75) bike successfully ... these are obviously road rims and much narrower. I just love mucking about with stuff 😎 Link to comment Share on other sites More sharing options...

NotSoBigBen Posted June 14, 2022 Share So job done, one layer of insulation tape over the spoke holes, two layers of duct tape ... 50ml of sealant, nothing fancy just what was cheapest at the LBS and 2 long tubeless valves from Grumpy at The Workshop. Amazing how resourceful that guy is, bloody hell! Little leaks here and there but a few rides and they'll settle in. Not only does the ride feel so much better but it looks the dogs b0ll0cks 😎 peetwindhoek, Mongoose!, DJuice and 1 other 2 2 Link to comment Share on other sites More sharing options...

I just love mucking about with stuff 😎 We used to run 2.4" tyres on 17mm rims back in the earlier days of MTB, and we're still alive. So as long as you keep your pressures under 50psi or so you should be ok. There are many charts online that will give opinions, the best one I've found so far is the Zipp calculator - https://axs.sram.com/guides/tire/pressure ChrisF and peetwindhoek 1 1 Link to comment Share on other sites More sharing options...

I'm happy at 40PSI so I'll keep it there, that's the bike I ride when I just feel like mucking around not for any serious training or anything Link to comment Share on other sites More sharing options...
