Been looking at these for a while ....
Always scared of getting a flat and wasn't keen on Mousses so ....
Bit the bullet and bought a set ... $100 US each ... a bit expensive but compared to a HD tube at $25 ea kind of economical given I replaced 3 front and 2 rear tubes this year ...
Followed the instructions which are very clear and simple ... thank goodness ..
Clean rim thoroughly ... put on rim tape ( supplied and is like narrow Duct Tape ) ... drill an 8mm and a 10 mm hole or use exsiting rimlock ones ... drilling one to 10 mm
Next is fit the small inner tube and pneumatic rim lock .... secret is to use plenty of soapy water and I mean heaps ... was able to slip it on with my hands ...
Next is to fit the tyre ... ( they recommend using new tyres - I used slightly used ones ) ...
Again heaps of soapy water all over the tyre beads and on the pneumatic rim lock ...
This is so cool and easy to fit or change a tyre !
You literally stick the rim inside the tyre with both tyre beads on the outside of the rim then just slip it on to the inside of the rim ... absolute piece of cake !! and no tube to pinch !! took like 2 minutes ...
Then tighten the big rear mean looking rim lock to 20 ft lbs .... then fingers crossed pump up the small inner tube to 110 psi ... yep 110 ...
And then the actual tyre - there are two valve stems - and fingers and everything else crossed all will seal and be good ....
I had 50% success .. rear was all good first go ...
The front hadn't sealed properly so following the instructions let all the aire out and slip the beads over the rim .... 2 mins again - poured in plenty of soapy water and bounced the deflated tyre a bit and tried again - bingo !! all good.
Pumped both tyres up to about 35 psi and left them for 4 days - held pressure like a bought one - maybe dropped 2 psi which could have been due to temperature changes ...
So rode on them today ... no issues and probably physcological but if felt lighter and was able to run 8 psi front and rear with no issues and great traction in the marbles...
Was a few rocky bits and purposely bashed through them - all good ...
So I will be running with them this season ...
Good Points :
- Virtually flat proof - unless you stake ya tyre
- Can run low pressures and even flat according to the blurbs I have read
- Tyre changing is easy and no danger of pinching a tube
- Appear to have a long life span compared to Mousses
- Reduces unsprung weight
- No need to carry tyre levers or CO2 kit - will still carry a small pump
Bad Points :
- Not cheap - US $100 each wheel
- Suppose to use new tyres
- Can be fiddly to get a good seal although I did use a used tyre
- Need a pump and tyre gauge rated to 120 psi +
