Edge_Design Posted October 28, 2016 Share That is a lot of CO2 canisters for that price! Cheaper and probably more convenient (they don't need a floor pump as well!): https://www.makro.co.za/diy/pg1?CategoryBusinessKeys=IHE&Category2=Air%20Compressors&Division=General%20Merchandise&Category4=Automotive&Category3=Wheel%20Care Link to comment Share on other sites More sharing options...

Simon123 Posted October 29, 2016 Share have compressor at home, and carry a tube on a ride. Yay! EUR60 saved. Link to comment Share on other sites More sharing options...
JohanMalan Posted October 29, 2016 Share A compressor does not always have a large volume of flow ,and very noisy, I gave mine to a friend and went back to a large volume floor pump.Bombs tend to congeal the slime.The garage is a dirty ride in the car away from my bikeshed.I think this is a fantastic idea esp on stage races or when touring.If you don't get it then maybe you have not done a large range of tyres on various rims seven 1 Link to comment Share on other sites More sharing options...
JXV Posted October 29, 2016 Share I have a high capacity 12V compressor in my 4x4. Remove tyre valve core, smear a little soapy water on the bead and compressor pipe direct onto valve tube. Hang the wheel from the tailgate. Never fails to seat the bead. Then fill sealant, fit the core and pump normally. I can see the advantage of this air tank on trips and in the race carpark if you don't have a compressor. 11 bar is enough. Most domestic and commercial compressors for air tools are regulated to 100psi (about 7 bar) so that's what you'll most likely fill it to. There is enough leeway for a hot car. But if you pump it to 11 bar then rather keep it cool. Sent from my SM-G935F using Tapatalk Edited October 29, 2016 by JXV Link to comment Share on other sites More sharing options...

JXV Posted October 29, 2016 Share I'm sure it must have a safety pressure release valveDidn't see one. Legally in most countries it doesn't need one unless it exceeds a certain pressure and volume threshold....I don't recall the values applicable in SA legislation.

Legally in most countries it doesn't need one unless it exceeds a certain pressure and volume threshold....I don't recall the values applicable in SA legislation. Sent from my SM-G935F using Tapatalk The pressure regulations used to have a "P x V" value, in the latest regs this was omitted. any vessel over 50kPa now falls under these regs, with a small list of exceptions .... Would be interesting to see the specialists debate if this vessel falls under the regs ... my guess, it does .... all regs aside - few things as dangerous as compressed gas in a vessel !!!!!!!!!!! This unit can, and should, be inflated with a floor-pump just prior to use. Link to comment Share on other sites More sharing options...
ChrisF Posted September 19, 2017 Share Had a perfect situation on Saturday where such a tool would have HELPED. Tubeless conversion was done a few days before the event. LBS clearly did NOT inform the rider of the process to ensure it seals properly .... just before the race she sees the front tire is very low on pressure. Grabbed my floor pump and quickly got that sorted ... to see the rear tire is just too on pressure. NOPE !! No way of getting air into that tire !!!! Sludge sealed the valve ..... I removed the core and cleaned as much as possible. By this time the tire had debeaded and just no way to get it to pop back on ..... In this situation driving to the nearest petrol station is hardly an option. C0 bombs ... just as well I did not start using my bombs, as cleaning the valve did not work. Last resort was to use a tube for the race. back at home this would not have been an issue, but with litterally minutes to spare before the start of the race that canister would have helped. Note to self - I must see if my 12V compressor is up to the task ... Link to comment Share on other sites More sharing options...

ChrisF Posted September 19, 2017 Share did you not try filling up the tyre with no core, then you just pop it back in(quickly)? much easier to seat the tyre too. JIP, tried it without the valve core. Just could not get it to seat .... tried the valve a third time, and realised it was a gonner .... With about 5 minutes before the race start we took out the rear tire and set about replacing the tube. Fitted yet another spare tube to the frame, while the pre-race talks were done .... The lady started stone cold last, and still won the ladies category over 55km ! In retrospect - POSSIBLE solutions : - spare valve (complete tubeless valve)- something to seat a tubeless next to the road (strong 12V compressor, floor pump with canister, this canister, CO catridges ....)- BUT, do you want to struggle like this just before a race ??? For this type of situation, fit a spare tube.- Then again, we drove up 500km to attend this event. Let's say I noticed my tubeless had issues hours before the race .... at what point do I stop repairing the tubeless and go for a tube .... I DONT presume to have the answers ! This incident has merely prompted me to think more about the options ... Also realised I dont have insulation tape in my toolbox in the car ... despite having a full toolbox ... maybe somebody learns something from this ....

ChrisF Posted September 20, 2017 Share I bought the Ryder pump tank unit - thanks to a special I got this for less than the Schwalbe tank. I always take the footpump with to events/rides So now I can also pop a bead if needed. And I also bought a set of valve inserts .... So if last weekend does happen again I should be sorted !

ChrisF Posted September 21, 2017 Share Murphy...... is ..... n ...... bl!ksem !! Start my morning commute, turn back to just top up the pressure in the back tire .... and the more I pump the more air leaks out (using the old floor pump) .... ligte ... brille ... cant find the fault, try again .... And the valve body breaks off !! fiets by die huis en twee karre by die werk ... Link to comment Share on other sites More sharing options...
