Ja sam shvatio da ima granicu, ovisno koji tip gume kupiš, no kako je to izvedeno nije objašnjeno.
Citiraj:
One “Casual performance” tire plus one 65psi fixed pressure control valve and one inner tube will retail for $64.95, but you can reserve this group for a pledge of only $45 towards funding their business plan. They will also be producing a “Pro” level tire with 95psi valves. You can reserve a set of those for $100, with retail for the set to be $149.90.
