Since then, different manufacturers have introduced their own systems that are not interchangeable so you must use a chainset that matches.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBCD - \u003c\/strong\u003estands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is only really needed when changing chainrings. To calculate the BCD, measure the distance in millimeters from the centre of any chainring bolt to the centre of an adjacent one and multiply it by 1.709 (you’ll likely need to round the resulting number up or down a little to get your BCD measurement).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCrank Arm Length - \u003c\/strong\u003ethis is measured from the absolute centre of the bottom bracket hole to the centre of the hole for the pedal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChain Width - \u003c\/strong\u003ethis is mostly only relevant for chainsets with a single chainring - if this is ⅛” then you must use a ⅛” chain. Almost all double and triple (and some single) ring chainsets will use a standard 3\/32” chain, the only exception being old chainsets designed for 3 or 4 speed freewheels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePedal Threads - \u003c\/strong\u003ethis must match the thread of your pedals and is usually stamped on the pedals themselves, most bikes use a standard thread of 9\/16” x 20 tpi. The exceptions being older French bikes, bikes with cheaper one-piece type chainsets and Shimano’s Dyna Drive system (easily identifiable as the pedal holes are about an inch wide!).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e*Intended Speed - \u003c\/strong\u003ethe number of cogs at the back the chainset was designed to be used with. We refer to it as ‘intended’ speed as most double and triple chainsets will actually work with different speeds than originally intended, but the further away you get from the intended speed the more likely you are to experience minor setup issues. The exception being some chainsets intended for 10 speed use or higher, with these it’s better to stick to the intended speed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e*Bike Type - \u003c\/strong\u003ethis is just a guide, any chainset can technically be used on any bike as long as everything's compatible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e*Matching Bottom Bracket(s) - \u003c\/strong\u003eif known, based on standard rear spacing of the period. For square tapers, ISO and JIS standards were introduced in the early 1990s; earlier cranks were designed to fit the proprietary taper. Alternatives can achieve the same chainline and clearance if the axle has the same taper and dimensions, and sticking to the same manufacturer and era will help. Mixing tapers is not recommended, as it can damage the cranks.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNB:\u003c\/strong\u003e “ITA” refers to Italian-threaded frames (70 mm BB shell).\u003c\/p\u003e\n\u003cbr\u003e\n\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Campagnolo","offers":[{"title":"Default Title","offer_id":57243771142525,"sku":"U-G3-CS150V","price":115.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0105\/7312\/files\/U-G3-CS150V-Campagnolo-Nuovo-Record-1049-Strada-Vintage-172.5-mm-Road-Chainset1_2f8ea2c8-e286-4542-8b7f-ea3ba7aa0d25.jpg?v=1761834368"}],"url":"https:\/\/www.pedalpedlar.co.uk\/collections\/chainsets\/ofmega+chainset+7-speed.oembed","provider":"Pedal Pedlar","version":"1.0","type":"link"}
