I just check the alibaba vendor, it says Type: Tubeless
but is it clincher compatible too ?? I am confused.
TLDR: It's a tubeless ready(TR)/tubeless compatible(TC) rim (these terms are interchangeable)
Meaning that it has a rim profile capable of accommodating a tubeless tire, but will still take a clincher as well.
In reality, most tubeless rims are actually TR
In fact, the difference between TR rim and a standard clincher is pretty small. To the point where some have success converting a clincher rim to tubeless. YMMV.
The rim profile on the TR just helps a tubeless tire mate better with the rim for a tighter seal.
However, there are dedicated tubeless rims where the spoke holes are covered, and they have a special rim profile to mate with special tubeless tires to create a seal with tape or sealant (eg UST tubeless).
This is not that type of wheel.
