Stays put once installed. I don't detach it to charge it. I assume if you always take it off the helmet to charge it the clips will get worn out. It's a great addition a bike mounted tail light. It's bright enough to grab the attention of others.
These bibs are incredible. I've tried several brands such as Rapha, Aerotech Design, BlackBibs, Neo, Gorewear and none of them give me the soft and complete flexibility of what Assos bibs do. I love the cross straps because they truly stop the chamois from moving around. The fit is a little more towards the racey side than comfort but I don't think that's a negative because it's like having a second skin as clich' as that phrase is. I will say my only small gripe is I wish the pockets had a reinforcement stitch at the opening because sometimes my phone camera bump catches the opening takes a little effort to get it fully in the pocket. A very small nitpick though. I'm an Assos buyer for life!
I recently had to replace all of my older bike shorts, of another brand, and I decided to go back to my old Pearl Izumi's that I used to ride years ago. The Men's PRO Short I found to be excellent, if you are looking for a very good thick chamois. These short are very tight, but offer excellent support and comfort, if you have the body for what I call a "race-cut". They are pricey, but so are a lot of the other top brands, but overall, a great short. I know it can be hit or miss with bike shorts, but I found the Levitate Pro Chamois to be excellent !
My hands were getting numb easily during rides I needed shake them out frequently to get the circulation going again. Not a big deal on a casual ride outdoors, but when I'm at the track I'm in the drops virtually the entire time and don't get much of a chance to relax. I've been wearing a pair of nice padded gloves, and I began to wonder if I had too much padding, so I opted to try the Assos. Almost all of the numbness has disappeared. These do have a "second-skin" fit, i.e., there isn't any additional padding and no seams in the palm of the glove. The palm is a thin, stretchy synthetic material, and I don't know how well they will hold up over time, but so far they have solved the numbness for me.
