First, the previous two listings both named a specific system (Praxis, Look BB65) — buyers searching this odd 31 mm bore will almost certainly be searching by frame or BB brand, so naming the systems it fits would help it get found. Second, if the 43.5 mm OD is a nominal figure rather than measured, worth confirming, since half-millimetre outer diameters are easy to mis-transcribe and the wrong OD is the one dimension that will not press in.\u003c\/span\u003e\u003c\/p\u003e","brand":"Easybikeparts","offers":[{"title":"Default Title","offer_id":55652761141624,"sku":null,"price":9.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/6675\/6923\/files\/IMG_3121.jpg?v=1788795185","url":"https:\/\/easybikeparts.co.uk\/products\/mr314357-2rs-bottom-bracket-bearing-31-x-43-5-x-7-mm","provider":"EasyBikeParts","version":"1.0","type":"link"}
