I bought a Canyon Spectral 7 CF with DT Swiss M1900 rims. The rims are tubeless ready from what I've read. I found a set of Stans universal valves in my parts box. Will my DT Swiss rims play nice with these Stans valves? I'm going to order the regular stans fluid off amazon.

Thanks

Are your rims and/or spoke nipples aluminum? If so, you might want to consider a non-ammonia based sealant. The valves will work in any rims except really deep ones (they aren't long enough, but you can get valve extenders or longer valves).

I find everything works easier if I put a tube in first for a few days. Make sure your tires are tubeless-ready.

I converted my Canyon Grizl to tubeless when I received it. The DT Swiss rims were already taped so all I had to do was deflate the tire, then remove the inner tube and install the valve. The tire was easy to put back in place and I then simply inflated the tire. The next morning the tires were still holding air even without sealant. I removed the valve cores and injected the sealant through the valve stem. After that I pumped the tires back up. Haven't yet had any sort of puncture and I only have to pump my tires after a couple of weeks. Due to an injury, I haven't ridden the bike for over 5 weeks and today I see that the tires are still holding air pretty well
The whole conversion job only took me about 20 minutes, but full disclosure I have been riding road tubeless for 12 years

Wouldn't your Canyon come with DT Swiss tubeless valves? My Inflite did, and it was a 2017 model.

I'm not a huge fan of those valves (and have had issues with them) as the nut tends to loosen up and there is no metal stopper on the inside. I prefer a stem like in this image that has rubber on the nut (doesn't loosen up), and some sort of metal on the inside to prevent the valve from pulling through.

Are you sure the tires aren't already set up tubeless?

Valves - I prefer the ones from Muc-Off.
Sealant - I prefer Orange Seal Endurance

I'm not sure now that you mention it. How could I check without disturbing the sealant in the case that they are already tubeless?

​​​​​​Look for a valve nut sealing the valve on the rim. Take the wheels off and shake them. Look through the small parts that came with the bike for tubeless valves, which is how my Inflite came.

Maybe, but it will hold air. Much worse than that holds air just fine.

Here's a couple pics. what do you think? There were no tubeless valves in the small parts box with the bike.

The valve stem nut is not a sure indicator of it being tubeless. Some people use those for tube valve stems, as well.

It's more obvious when there's a silicone ring under the nut to form a seal, but I guess your Stan's valves didn't have that so it's inconclusive. Honestly would be easier to just shake or spin the wheel to hear if there's any sloshing. If not, just break the bead at the 12 o'clock position and look for a tube. Hardly any sealant will come out.

Loosen the retaining nut and push the valve into the tyre - if it vents air and sealant then it's tubeless, if it holds air there's a tube.

If they are tubeless they may have a bit of sealant inside if it’s not dried up. Remove the stem cap and see if the stem has a removable valve. There should be flat sides just below the presta valve lock nut. If they are there it can still be a tube but you remove the valve. If it is tubeless there should be residual sealant.

There are few YouTube videos on how to check sealant. Here is one.
