Specialized Tarmac: Only an Idiot Would Buy This

A Specialized Tarmac SL6 arrived after a bike mechanic couldn't remove a seized bottom bracket In this video I inspect the frame, measure the BB30 bearing seats, explain why the interference fit is out of tolerance, and machine the shell so a Hambini bottom bracket can be installed correctly. Specialized bikes are marketed as the muts nuts for engineering, speed, holding their speed etc. It is essentially verbal diarrhoea to empty your wallet by proxy. If you have half a brain cell, buy a different far eastern bike. They are all the same, they just slap a different badge on them. You just pay for less western middle men to whack on their hair care fee. Along the way I cover: Why BB30 bearing fits are so critical Correct circlips vs horseshoe retaining clips Measuring bearing bores accurately Why excessive interference causes seized bearings Internal inspection of the carbon frame Installing a precision Shimano conversion bottom bracket Final assembly and spin test You can support my journalistic career on Patreon   / hambini   I'm also on Facebook and Instagram   / hambinieng     / hambinieng   Website https://hambini.com Discount codes: https://www.hambini.com/hambini-bicyc...
