I hads a Cannondale handle bar bag for 3 or 4 years over time and exposure it finially disintragrated. I couldnt find a cannondale to replace it so i ended up with a topek. Now most things made by topek are good in my opinion. This handle bar bag wasnt. IT was sturdy enough even too sturdy. Because of that it was heavy even when empty. The mounting system was similar to the c dale. but a little cheezy the brackets were cheep plastic the heavy bag kept sliping under the weight i wasallways adjusting it and retightining the screws . Being made of plastic the mounts gave way and failed (broke) about 700 miles into a long tour so i ended up using the bikers friend DUCT TAPE to hold it on for the rest of the trip.
ILL take the cannondale.
