Hi all

Just got my set up exactly the way i want it....
Have FFWD Ryot 44s With GP 5000 STRs 66 PSI (font) 70 PSI (rear) using MilKit valves.
Have swapped cassette for an 11-32 and the rear cage from short to medium.

All is well
Except both tyres are loosing air and have become significantly softer over the course of about a week.

Is this normall with Tubless..?? If so i shall need a track pump.
Any recomendations and what to look for \ avoid.

No signs of the source of the leak no evidence of punctures.
Best
Paul

I'm assuming you have put sealant in already. Have you ridden the bike on a decent length ride yet? I find that helps settle everything down.

And buy that track pump, it's an essential tool no matter what tyre set up you have. Don't skimp on it either.

Pretty much standard with tubeless; air loss over a few days is normal. Some setups are better than others; just check before riding and add some pressure if required.

On a seperate note you mentioned changing from short to medium cage. Have you swapped the entire rear mech or just the actual cage? I ask because Shimano rear mech's have different parallelograms depending on whether they are short (SS) or medium (GS) and swapping the cage on its own will result in sub-optimal shifting.

Thanks for that !
TBH I never swapped it !!, Im not sure what a parrellogram is (reff a Bycicle) My shop did the fitting and chain replacment. In terms of performance id say it was even better than before.
(Was swapped as he SS does not support an 11-32 \ upwards cassette)

I’ve been using this boy for years, many tubeless setups done.

All the spare parts available online (but generally I haven’t been forced to swap any although almost everyday use).
Quite cheap and very reliable
Highly recommend!

Air loss depends on many variables. The tire used is very important. Pirelli Speedcore, Goodyear and Tufo/Enve tires are wonderful for air retention. The last gen Goodyears would lose maybe 2psi in a week. The rest will lose maybe 2-3psi daily. That’s better than any latex tube.

I'm using this. One of best for price you can find out of China. Can easily setup TLR such as GP5K STR, Schwalbe Pro One, Tufo Comtura 5 TR, etc.

Have the same pump. Still going strong after 5 years and I pump up tires before each ride. Seated tubeless tires with it also. :beerchug:

+1 for the Joe Blow. Inexpensive and very good, also good for car tires 😇

If committing to tubeless it is worth having a chambered pump that can deliver a blast of air to seat stubborn tyres. New tyres generally seat without complaint but older tyres being re-mounted can take a bit of coaxing to get back in the saddle, so to speak.

I have an Airshot for that eventuality and it has seen a fair bit of use.

Cheers All

I was pretty much committed to that pump seemed a reasnoble price and if i get 5 years out of it i will consider that a good return.
(Tho i did purchace from my preffered on-line reseller)
+ Unless replacing tyres im hoping there weill be no need to reseat the tyres in situ. As the MilKit valves let you Check Sealant, Remove old sealant and Top up sealant with the tyre still seated (but with a significantly reduced pressure) Not tried yet tho..

BTW have some blingy Lezynne Valve caps on the way which double with a core removal tool v sexy.
