I've used a wide variety of chamois creams in my 25 years of cycling and Enzo's ButtonHole is by far my favorite. Works great, smells great, just that little bit of menthol to add to the warmtingle factor... and is a reasonable value unlike some of the other products on the market. Highly recommend this stuff!
I use the system when I'm going long fast rides (100-200 miles) in hot weather. It is fast to refill and is out of the way. Works great! I also use it for time trialing since it's out of the wind. I use to slip a CamelBak bladder into my skinsuit, but it would move around, which is entertaining, but not real good for maintaining focus in a TT! Would be nice if it had a bit more room for tubes & CO2, but my biggest gripe is getting the thing open. I must have t-rex arms from riding too much because the lid seal is a bit stiff. Other than that, I love it!
For the price, the bag works fine. As the previous reviewer mentioned, the straps are a bit on the long side. You'll also need to make sure that the straps are line up well or you'll get some clothingvelcro rub on out of the saddle climbs. My biggest problem with the bag is the size and shape makes it very difficult to access a down tube water bottle, even when I use a small bottle. I have a 54cm Specialized Roubaix, but the problem is encountered on all my 54cm frames including the more traditional geometries. This is unfortunate since I got the bag for longer rides when 2 water bottles is a necessity. Quite frankly, I think the bag would be much more useful if the redesigned it to by reversing the bag and utilizing the topseat tube rather than the tophead tube. They could then increase the angle of the large portion of the bag so that it would hold more
The Iris cage is sleek and sexy, and gently flexes to hold a variety of water bottles. I use stainless Klean Kanteen bottles, that rattle in other cages and are held securely in these. Made in USA, steel is real. LOVE these.
