The answer to my handlebar grips problem

The stock handlebar grips of my Marin Alpine Trail 29er were slipping. I put some adhesive but the problem recurred after sometime.

I was thinking of replacing them with grips with lock-on.

Yesterday, I brought my bike to the bike shop, where I bought it, for the replacement of the broken spoke and for tune up.

There, I found the answer to my slipping grips. I bought a pair of the lock on grips and replaced the old ones. The brand of the grips is Answer. A pair is P1,100.
