Hambini Roasts: Trifox X10
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
SRAM GXP Cranksets: An Engineering Guide
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…
Bike Bearing Grease: A Practical Guide to Bearings and Assembly for Bikes
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…

Bicycle Wheel Power Data 50km/h
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…

Winspace LUN Hyper Wheel Teardown
The Winspace Hyper are highly regarded, they have very good aerodynamic properties and are comfortably one of the fastest wheels you can buy. 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 you want a bit…
Canyon Aeroad gets roasted.
Canyon’s new aeroad has been plagued with failures around the seatpost. Now sales have been suspended and they are looking to introduce a new design.
Scott Foil gets roasted on the Hambini barbecue
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.
Hambini BBright DUB Bottom Bracket
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
