Sportaid Front Caster Tube 8 x 1-1/4 in, Straight Valve
Pneumatic 8 x 1 1/4 in casters give a softer ride than solid ones, but their small tubes are easy to pinch and wear out faster than rear tubes. This replacement has a straight valve stem and is listed as fitting most 8 in caster rims. The retailer notes that its photo shows the 45 degree version, which is sold separately, so make sure you order the stem style your rim needs.

Sportaid Front Caster Tube 8 x 1-1/4 Straight Valve (2546): common questions
Straight or angled valve: which do I need?
Look at the tube you are replacing. If the stem leaves the rim at an angle, order the 45 degree version.
Does the photo match the product?
The retailer states that the picture shows the 45 degree stem, while this item has the straight one.
Does it fit 200 x 50 casters?
No. That size is closer to 8 x 2 in. Ask us for the 8 x 2 in tube instead.
