On square impacts, the Air-Liner’s resistance ramps up while it compresses to prevent rim strikes and pinch flats – it’s basically a shock installed in your tire.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eIn addition to big-hit resistance, the Air-Liner Gravel lets you run a lower PSI, which lets your tires gobble up stutter bumps that would otherwise filter up through the bike. You’ll still feel a connection through the contact patch, there’ll just be less static from gravel chatter – and less accumulated rider fatigue from that chatter filtering up through the seatpost and bar. The Air-Liner Gravel’s profile reinforces the sidewall for stability while cornering, and it locks the tire against the rim bead. It also lets the tread ride on air, maintaining contact-patch conformity for responsive traction while climbing and braking. No folding, no burping, no sluggishness, and no flats.\u003c\/span\u003e\u003c\/p\u003e","brand":"Vittoria","offers":[{"title":"700X31\/40","offer_id":67931535606066,"sku":"1AA00019","price":1140.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0720\/3389\/4706\/files\/BSC-Products-7-1-6.jpg?v=1791446071","url":"https:\/\/bellscycling.co.za\/products\/vittoria-air-liner-tire-insert-size-gravel-31-40mm","provider":"Bells Cycling","version":"1.0","type":"link"}
