We have seen some dramatic developments in extension design in the past 12 months. A team mate of mine did some experimentation with foam and heat shrink. I copied him using balsa wood (!)

Aero testing at Welwyn 2019
I wanted to compare the CdA of my current “tall and narrow” position to the low position that I used in the 2014 season, to see if it would be worthwhile doing another six months, over the winter, re-adapting to a low riding position.
Uvex Race 8 versus Met Drone
I hadn’t had the opportunity to test the Met Drone against the Race 8 until recently. I did one set of tests before our club circuit TT last Wednesday and another set of tests today. The results were consistent within the margin of error.
P3C set-up for the 2019 season ….
My 51 P3C was getting a bit scruffy, it was time for a re-finishing. Here are some details of the changes and components used to set the bike up for the 2019 TT season.
Pinarello Winter set-up
My focus in the winter months is on training and preparation for the next season. Most of my training is highly structured workouts on the turbo, however, I do get out and do some real world riding occasionally, and this is the bike I am using at the moment ……
Measuring saddle positions
The standard method is to measure height from the ground and off-set of the saddle nose from the centre line of the bottom bracket. This works well on a single bike but is not ideal when trying to replicate the back-end geometry between different bikes. Here’s an alternative method that I use …..
Options for the front end
If you go to an event and observe the riders on time trial machines you will see a wide range of front end positions. Getting the most efficient position for both aero performance and power production is the Holy Grail. In this post I attempt to give some structure to the process of finding that position ….
Test session at Newport Velodrome 28th February 2018
I book a three hour slot at Newport Velodrome once or twice a year, and use the data to validate my “open field” test results and to refine options. In this session I was benchmarking a 54 P3 with a new configuration of bars and wheels. In parallel I tested some shoe and helmet combinations.
Wheel and tyre comparisons
Some pretty basic wheel and tyre comparisons – I’m limited by the availability of wheels and testing equipment, but …..
Drive Train Options
I guess we’ve all heard of drive train losses and drive train efficiency. There was a blog post on “keeping it clean” 13th October 2016. I’ve talked to a few people since then, and picked up some interesting tips.
