In a nutshell
Transport bag reduced to the essentials, without padding, for road bikes up to a frame size of 60 cm and bikes up to size XL, with space for handlebars up to 80 cm wide (information for borderline cases without guarantee, as wheelbase and tyre dimensions also influence the effective packed size, especially for bikes).

TRAVEL LIGHT bicycle transport bag in detail:
Unpadded transport bag for road/gravel bikes up to a frame size of 60 cm and bikes up to XL (handlebar width up to 80 cm). Thanks to its low weight and packed dimensions of (Ø19 x H12 cm), the bag fits in a backpack or on the frame. This simplifies logistics on tours with different departure and arrival stations. High-quality materials: the upper part made of tear-resistant ripstop nylon, the base made of robust Cordura with PFC-free impregnation, and the sturdy YKK quality zip guarantee a long service life. For easy packing, the zip starts at the front at the height of the fork crown and extends to the bottom at the rear. For transport, the front wheel is removed from the fork and secured to the frame with the two supplied tie-down straps. The packing bag with padded base serves as fork transport protection. (VN)
