In 2010 Osprey Packs entered the fray of mountain bike / adventure racing hydration packs. They released a series called the “Hydraulics.” They have done an outstanding job with the Raptor 10 pack (competitor to the Camelbak Mule).
For those of you unfamiliar with Osprey Packs, they have been around since 1974 and have been primarily a backpacking pack maker. This reviewer has been using Osprey packs since about 1993 or 1994. One thing that I appreciate about Osprey is that they continuously make improvements to their products, never satisfied that they have, “arrived.” This is quite apparent with the Raptor 10 pack.
The Raptor 10 has approximately 600 cubic inches of storage, holds 100 oz of water, and has three zippered compartments. There is also an outer stretch woven pocket for a little external storage - visit the Osprey website for more information . The “key features” tab has some very informational pics as well. Some other cool features include: a built in magnetic retainer for the bite valve, pockets on the belt to hold some food / energy stuff, and a bladder that’s worth an entire review itself.
Here’s a quick way to shave half a pound or more of rotating weight from your 29er trail or race bike. Stan’s new Crest rim offers similar weight to the company’s 355 but provides a wider rim cavity (21mm) than the Arch or 355 in order to maximize tire volume. At an average weight of 370 grams, these rims are a full 100 grams lighter than the Arch.
