Pressfit vs Threaded Bottom Brackets
There are various camps out there on the internet that swear by threaded bottom brackets as a means to avoid creaking. This video below shows the pro’s and con’s of both.

9Velo is a relatively new company based in the Chinese coastal city of Xiamen. They are well versed in the manufacture of wheels with a claimed 50 years+ of combined engineering experience within the organisation. These CD55 wheels are the first to feature their new axial freewheel system which has up to 54 teeth of engagement. This is a well engineered wheelset and good value for money.
The Elves Vanyar is a one piece moulded carbon fiber frame produced by the Taiwanese/Chinese company Elves. The frame was sent in by a viewer and thus the purchase was anonymous. Overall the frame was nothing more than average albeit no worse than the likes of the named brands Cannondale/Canyon etc

If you are about to buy a Cervelo bike, watch this video. It shows the appalling tolerances the bike frames are made to. The bottom bracket pressfit specification is so bad, neither NTN or SKF will warranty their bearings in it. This particular frame had misalignment between the two halves of the frame body.
Blind bearing pullers, initially created to remove bearings from rotating equipment without rear access, have been popularized for removing wheel bearings. Despite their increased use, these tools can inflict unnoticed damage on wheels. Primarily deployed in automotive and machinery maintenance, blind bearing pullers slide through the bearing, expand behind it, and retract, exerting a steady force without damaging surrounding areas. However, concerns arise when these tools are used without considering potential damage to internal preload spacers, causing potential legal repercussions for negligent installation in professional settings.
