1. What is the benefit of using a Rock Bar case? -- The benefit of the Rock Bar case is that it is a multipurpose low profile gear storage case or a case used for holding weight pouches. It is designed to hold extra gear without getting in your way due to its low profile design. The design allows it to be used on handle bars, under the top tube, under the down tube, and on forks. Store extra gear such as a tube, patch kit, food, tools, small bottles, etc. for long rides, or on the back road or trail less travelled. More than one Rock Bar case can be attached to your bike. -- The Rock Bar loaded with weights is ideal for adding weight to the bike without affecting the handling of the bike when the Rock Bar case is attached to the down tube or top tube. The Rock Bar Case is strong and holds 7 pounds of steel weights. Weights are available with the Rock Bar case. 2. How big is it? -- The Rock Bar case is 32 cm / 12.6 inches long (inside space of about 28 cm x 5 cm x 6 cm) and can hold items such as tubes up to a 2.1 width, small pump, tools, energy bars, 8 oz energy drinks, batteries and other items (not necessarily at the same time). What you use it for is up to you. 3. Where do I put the Rock Bar case when attaching it to a bicycle? -- A Rock Bar typically is attached to the underside of a bicycle frame down tube or top tube, attached to the handle bar, and optionally attached to the leg of touring or MTB forks. Two or more Rock Bars can be attached to a bike at the same time. 4. If I use a Rock Bar case with weights, can the weight amount be changed or removed? -- The weight amount is completely adjustable and the weight is removable. The Rock Bar case will hold the weights in a stable position. 5. Who should use a Rock Bar case with weights inside? -- As an exercise tool the Rock Bar case is for anyone seeking to gain strength and wants to incorporate another technique to help them do so. 6. What is the best location for weighted training if I use one Rock Bar case? -- The ideal location is below the down tube and bottom bracket. This position gives the most neutral balance. The second popular location is under a top tube. This position will make the ride a little harder since the bike usually sways from side to side a bit when riding, and thus will require more muscle force to center the bike.
