Fresh from YouTube is another Hambini Bottom bracket install. This time in a Yoeleo R12. This is a revision of the R11 bike Frame that The Unabiker had issues with and it highlights the problems of frame tolerances. The bottom bracket is made to much tighter tolerances than the frames they are pushed into.
Here is a video posted by The Unabiker on YouTube. In it he describes some of the problems he had with his Yoeleo frame and specifically trying to fit a Hambini Bottom Bracket into it. Yoeleo have historically had decent tolerances but it shows that nobody is immune. The check to get it fixed and…
Farsports are a chinese company that has been in the wheelset business for a number of years. Their products have been widely used amongst budget conscious riders wishing to get the best bang for their buck by buying directly from the far east.
Campagnolo cranksets have a reputation of being well engineered and robust but they are not without their problems and quirks. This post explains one of those in detail which surrounds the myths of the preload system, the “safety clip”, the system stiffness (or lack of it) and the involved nature of a bearing replacement. Campagnolo Ultra Torque is found on many of the upper range of Cranksets including the Super Record and Record.
StylishRiding, a viewer of the Hambini Channel videoed their installation of a Hambini BB30A to Shimano bottom bracket and uploaded it. You can view it below
This Teardown covers the Engineering behind the ROTOR 2InPower 30mm Crankset. It focuses on the materials, manufacturing, tolerances,, bearing preload system and system stiffness.
The axes and planes that would affect the handling and braking of the bike are well above average. Machining quality of the parts was excellent. You can see the video of the review below You can get the bike frame from the Trifox Website
This article will cover the technical and engineering aspects of SRAM GXP. Sram GXP is a very popular crankset standard used by SRAM. It offers an industrial based bearing arrangement and was touted as having the lowest weight and rolling resistance of any crankset bottom bracket standard. The engineering will be analysed in detail. Currently…
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…
Over several years, bike wheels have been tested for aerodynamic performance. To date, this is the largest independent dataset available. Popular brands such as DT Swiss, SwissSide, Shimano, Mavic and Bontrager have all been tested. This dataset was originally derived from wind tunnel test data but has latterly moved over to Dinitriev number with a…
