so what do i need? i have a trek remedy 7 from 2009, with the original rhythmn wheelset, the rims say tubeless ready on them, but aside from tyres, what do i need to do to go tubeless?

Get a front and a rear strip….

Couple of valves

and some sealant (I found the Bontrager one rubbish) currently using Specialized stuff with no issues
top tip: you might need to fit the tyre onto a normal wheel and pump up hard overnight – this will stretch the bead just enough – only really needed if the tyres have been lying about for a while.

Had my set up for a year – well worth the brain retraining required!

Probably worth getting fresh tyres, if you've had lots of punctures and/or you live in a thorn/flint area.

I have the same wheelset and all you need is some valves (about £6 a piece) Tubeless tyres! and a bottle of stans sealant. The best tip i can give you is to rub some fairy liquid around the rim edges prior to inflating. This helps the tyres to seal on the rims. I use a standard track pump to inflate them. There is a bit of a technique to it but persevere and you'll reap the benefits! i've had one puncture in the last year which was caused by hitting a stone step head on causing a massive burp which was easily re-inflated. Make sure you carry a CO2 inflator with you and a couple of gas cartridges too.
