Redline Liteflight Tube 20 x 1-1/8 (451 ISO), PRESTA Valve

Great price and fast service.

Just what I needed , can't find at any regular bicycle shop !

Its not the seller on Amazon's fault, but I found it listed as 56 grams on two other sites. When I received them they weighed 74 grams. That is without the cap or stem nut.
