Review on Zéfal Pulse Bottle Cage by Bryan Gilliam

I really liked this fiberglass bottle cage because it stretches easily and securely holds larger 1 liter Zefal and Science in Motion (SIS) bike bottles. cycling water bottles. weighed 36 grams. Zefal has stopped its production. Looks like it has been replaced by Zefal Pulse B2, 31 gr. which I haven't tried yet. The Zefal LT1 also expands to accommodate larger bottles, but I'm not sure how safe that will be as I'm still testing it.
