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.
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
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. The video was removed by YouTube for harassment, IT WAS NOT TAKEN DOWN VOLUNTARILY. but you can view it below on Odysee.
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.
This video uploaded by youtuber Peak Torque shows a Hambini BB having it’s engineering tolerances judged. Some key points It’s a BB86 Shimano Racing Edition Bottom Bracket The bottom bracket tolerances are accurate to 0.005mm, that is less than the diameter of a human sperm cell. The eccentricity was found to be 0.010mm (0.0005inch), the […]
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.
