You won't want to be carrying loads of luggage on on your urban fixed gear but you'll probably want to carry something. At 1.5 litres this Top Tube Bag is just about perfect.

It's got a Hypalon Cover on the YKK zips, X21 waterproof fabric with nylon lining and rubberised strapping to provide extra grip to the frame and stem.

It measures about 10cm tall and 37cm long.

Another great product from Restrap 100% handmade in Yorkshire, England.
