T47 is examined in engineering detail. Some of the quirks associated with the standard, the weights and the frame geometry limitations are discussed. Trek, Felt and Factor variations of T47 dimensional standars are covered.
Introduction Grease is an often talked about but little understood. It can have a significant impact on performance on a bike specifically in the area of transmission frictional losses (watts). This guide covers the practical aspects of using grease as a lubricant and as an assembly aid. Following a number of questions arising from a […]
The Winspace Hyper X 50mm are highly regarded, they have very good aerodynamic properties and are comfortably the fastest wheels you can buy in 50mm rim depth. The Winspace hubs use standard 6000 series bearings of common sizes. This video shows you how to remove the bearings and replace them if they are worn or […]
This Scott Foil had it’s aerodynamic credentials severely burned on the Hambini barbecue. Staggeringly, the frame was the user’s second. The first was found to be out of specification. This frame was also found to be out of specification.
A user from Australia sent these video clips in showing the before and after on his SRAM Quarq dub power meter crank set axle. As always, an unloaded test is not a good indicator of loaded performance but it does highlight good alignment Here is after
A Hambini bottom bracket user from Canada sent this link to their mechanic installing a Hambini BB into a Cervelo bike frame. The music and install are quite therapeutic!
A Hambini BB user sent in this video of his Specialized Tarmac SL6 with a Hambini BB30 to Shimano Bottom Bracket installed. As always, an unloaded spin test is not a good indicator of loaded performance!
One of my viewers contacted me about an issue he was having with the installation of a set of NTN bearings. He purchased what he believed to be Loctite 641 from an online supplier, this was promptly delivered with a label indicating it to be “high strength”. This is incorrect as high strength Loctite is […]
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.
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.
