For longer rides and tours, having a bevy of tools for small fixes and repairs at your disposal is highly encouraged. And while throwing a few hex wrenches in your saddle bag is useful, a tool such as Crank Brothers' b17 Multi Tool, is just as light and features all the tools necessary to keep your ride on schedule. It will also negate having to make that call to your significant other for a ride home. The b17 weighs in at 230grams, and while, sure it's added weight, it's a small price to pay for peace of mind. The b17 was constructed from stainless steel durable, beautiful and resistant to rust. Leave it in your seat bag year round without worrying about corrosion. The tool bits are 25mm long which makes it easy to reach hard to get to places on your bike. The b17 includes the same tools as on the b14: hex bits in sizes: 2. 5, 3, 4, 5, 6, and 8, a t 10 and t 25 torx, size 1 phillips and flathead, size 2 phillips and flathead screwdrivers, and a magnetized bit socket driver. Additionally the b17 features two spoke wrenches and a chain tool. Now you won't be stranded when your chain breaks on the gnarly uphill. The Crank Brothers b17 Multi tool is available in One size and in Stainless Steel.
