Featuring an open skeletal design and a dual mid-bolt wedge mounting system, they are lightweight yet maintain a very high level of strength. A 53mm extension stem weighs just 218 grams\/7.7 ounces. By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, we reduced the weight and size and eliminated a serious hazard to the rider’s knees.\u003c\/p\u003e","brand":"BOX BMX","offers":[{"title":"Default Title","offer_id":55353934381432,"sku":"ASBX2C853K","price":78.2,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/9434\/1977\/files\/ASBX2C848K-bx-two-centre-clamp-stem_f8cc3c0e-0406-423c-9517-85f507490969.jpg?v=1775822728","url":"https:\/\/www.bikeparts.co.uk\/products\/box-bmx-box-two-22-2-x-1-1-8-centre-clamp-stem-black-53mm","provider":"BikeParts.co.uk","version":"1.0","type":"link"}
