Depends on the ground conditions with me, but my preference is gloveless.
If it’s a stoney, gravelley place which is fast which i’m trying to ride fast, i put on gloves.
If the ground is just soil, no stones or gravel, i much prefer gloveless. It’s my BMX ways. I like thin soft grips and having lots of feel.
I think it most probably comes down to what kind of rider you are for preference. If you’re the sit in the saddle, passenger type of XC/trail rider, you’re not really looking for ultimate feel and control. At the other end of the spectrum, if you’re a freeride/attack what ever is put in front of them, really nailing it, type of person, I would think the extra feel and control would be welcome.
Your hands are your first input/last feedback from/to the bike, people are going to have they’re preferences if they’re after a lot of control.
Though of course as with everything when it comes to bikes, it’s 100% personal preference. There’s no right or wrong. i think too many people get too hung up on doing the “right” thing rather than what is actually what they prefer.
