Bolt/Nut Black Plastic Domed Caps

[2017EX_imp]

Looks great, but I'd be interested to how many come off after a few bumps

I had considered that, but so far neither the caps supplied with my Motech bars, or the caps I ordered have had any problems. At the minimal cost of $2.50 for a pack of 10 for each size, I figured I would have spares, and no big deal if some failed. The caps actually stretch slightly pressing on, and the fit consequently is tight. The caps are not difficult to remove if necessary, but do take a deliberate, strong grip to pull straight off. Should a cap get loose, a dab of clear silicone adhesive inside the cap would take care of it, but I dont think it would ever be necessary, based on what I have seen so far.
