Sportaid Front Caster Tube 8 x 2 in, 45 Degree Valve
Wide 8 x 2 in pneumatic casters sit close inside their forks, and a straight valve can be hard to reach with a pump head. This tube has its stem angled at 45 degrees so that it points out to the side of the wheel. The retailer lists it as fitting most 8 in tires of this width and also sells a 90 degree version of the same tube at a lower price.

Sportaid Front Caster Tube 8 x 2 with 45 Degree Valve (2545-45): common questions
Is this the same as a 200 x 50 tube?
The two markings describe a similar caster size, but the retailer lists this tube only as 8 x 2 in. Send us your tire marking to check.
Why choose an angled valve?
On small wheels the hub and fork crowd a straight stem. An angled stem leaves room for the pump head.
Is the brand stated?
No. The retailer does not name the tube maker.
