The F50S is a 'standard' size frame bag from Stealth. Designed with a 50 degree angle between the top tube and down tube, this bag will fit a good proportion of the road, touring and cyclocross bikes on the market today.
With 2.4L of capacity, a sturdy and modular daisy chain attachment, the F50S will be right at home inside your frame, enabling you to carry a multitude of items from your favourite drink, to a jar of sauerkraut, whatever floats your boat.
The bag allows for some change in angle so will fit bikes with a down tube - top tube angle from about 45-55 degrees. To check the fit simply print the below PDF as an A3 and check the fit against your frame. If your bottles get in the way then the Wolftooth B-Rad adaptor can be used to move the cages down.
Comes with 1.5m of back to back Velcro for attaching to the frame. Simply cut to desired length to suit the frame and slide through the slots where suitable.
