Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

questons about going tubeless

Ok so I am my own mechanic and build my own wheels and never really have thought about going tubeless. So far it seems I would have no advantage or reason. I have Kinlin BDOP DIY wheels I built. I run Conti Grand Pri 4000 II (23mm) and have not had a flat in my 2 years or so. I run 110-115 front and 100 rear at 175 lbs. I really have no issue with ride quality and going less psi is not something I care about but seeking opinions. Could it be going tubeless is safer on descents or turns?

Is going tubeless better and will I see any improvement? Finally what do you need to make the change. I pretty sure these Kinlin cx279 rims are tubeless compatible.

those hoops are not tubeless compatible.

Oh thanks I thought they were. In any case they are good hoops. I was thinking of building a set of DT Swiss 440's with OC rear 28 24 and some novatec hubs, with plain out DB wheelsmiths spokes and brass nips.

If you haven't had a flat in two years, I personally wouldn't change a thing.

Do you really run more tire pressure in front than in back? I think you've got it backwards.

Most ride with a slightly higher psi in the rear tire to support the heavier weight in the back vs. front. However, tire pressure is a personal preference.

Edit: cross post with above. Noticed the same thing.

As it seems you prefer gambling over taking proactive flat prevention measures, and that you're so comfortably certain about what you haven't experienced, then I say yeah, don't bother with tubeless.

However, if the way in which your certainity about the Kinlin's being tubeless compatible turned out to be false prompts you to reconsider your other assumptions, then you may find some potential benefits in going tubeless.

No matter how you cut it though, no one needs tubeless, so you'll have to be working on a more sophisticated assessment than that, e.g. a more nuanced understanding than "I don't get flats, ergo I don't need tubeless."

I got a new set of Ksyrium SL's in 2012, after 12 years on the Heliums, with 2 flats over that time. I had never heard of road tubeless until I read a.review of the SL's where the tester ran some Fusion 3's, and loved the ride. So I ordered a.set, and haven't gone back to tubes yet. 23 mm tires running 80 R and 75 F. Try it,!you mightnlovenit n

I run tubeless in my commuter. Sector 28s on Stans wheels. Really nice. Really like them.

I will tell you, while you won't get flats in the traditional sense, a puncture takes time to heal with sealant.

During that time, a 27 tire will drop from about 90psi to 20 or 30 psi. So while you are not swapping tubes, you will certainly pull over and add air. I imagine this would be worse on smaller sized road tires.

For what it's worth...
