Wowlife 4X Bike Bicycle Road Racing Colour Presta Valve Cap Dust Covers: Enhance Safety and Protect Your Bike Review

Aluminum. Easily bolts onto the Presta valve stem and will stay in place all summer with about 2,000 miles with no sign of loss or failure. Doesn't snap unlike the plastic caps you might be used to.

I know most people just throw these caps away, but I hate getting dirt on the Presta exhaust valve threads. Aluminum caps simply hold up better than plastic caps because the threads have a hard stop and if you choose aluminum it can also be color matched to the bike.

The caps are ok. The problem is that the delivery time for this product is about a month, which is not clear from the description. There are many other options for a similar price with the same quality but faster delivery and I recommend choosing another option.

I'm tired of changing plastic split caps and they promise to be much more durable and attractive. I had a shipping confusion but was amazed by the fact that when I tried to contact the seller (at least over the weekend) I received a response within minutes and corrective action was taken immediately.

They fit. They stay and look neat. they didn't fall off. They're aluminum, too, so they'll probably be around for a long time if you lose them. Good to have 4!Oh, and the purple goes really well with Hope's tech components.
