It suits riders who already have a compatible Praxis M30 crank and want a conventional threaded installation rather than a press-fit solution. Compared with the ceramic-bearing version of the same M30 BSA bottom bracket, this SKU uses steel cartridge bearings. It is not a universal interface for every crank spindle, and it should not be confused with Praxis M30-Thru hardware, which uses a different bearing arrangement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStepped M30 \u003c\/strong\u003e\u003cb\u003eInterface.\u003c\/b\u003e The M30 system uses a stepped bearing arrangement that matches the Praxis spindle design. In practice, that means correct crank identification matters more than simply matching the frame's thread standard. A drive-side wave washer provides bearing preload, while the forged and machined heat-treated alloy cups thread directly into the frame shell. This makes the bottom bracket a specific interface between a compatible Praxis crank and a BSA-threaded frame, rather than a generic conversion part.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCheck Crank Compatibility.\u003c\/strong\u003e Installation requires a Praxis M30 socket-style or wrench-style tool, which is sold separately. Before ordering, confirm that the frame is BSA threaded and that the crank is a standard Praxis M30 alloy-spindle model. If the crank is M30-Thru or another manufacturer's spindle system, this is not the correct bottom bracket unless Praxis explicitly lists compatibility. Praxis also offers an M30 bearing rebuild kit for later bearing servicing.\u003c\/p\u003e","brand":"Praxis","offers":[{"title":"Default Title","offer_id":48009793700001,"sku":"PXS-68-0202","price":3100.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/5869\/2257\/files\/ShopifyProducts_52859d79-5c00-456e-af0f-acee9b5c03af.png?v=1791176251","url":"https:\/\/www.thebikeaffair.com\/products\/praxis-bsa-m30-68-73-threaded-bottom-bracket","provider":"The Bike Affair","version":"1.0","type":"link"}
