I’ve been to the Bike Whisperer – he’s now based at Greenham Common (/Star Wars Rebel Base) just outside of Newbury which was very handy for me.
He’s excellent – spends a lot of time on the person before getting on the bike, lots of tests of alignment, flexibility, proprioception etc. He admits some of it is a bit weird but he sometimes learns things from the less obvious tests – e.g. one is to stand with your eyes closed and arms crossed over your chest and to march on the spot. Most people rotate in some way which might indicate a difference between legs.
We also spoke a lot about the type of riding I do and what I’d be doing in the future. I tend to do long endurance stuff so there was an aspect of 8 hour+ comfort to be considered in the position.
Fitting then starts with shoes and cleats before adjusting other elements on the bike. I was very lucky in that I didn’t need any cleat or shoes wedges (which most do) as I’m naturally aligned. In the end only a few minor adjustments were made from my previous position (which had been done by Epic Cycles as part of a purchase 5 years before).
Everything is done by eye/experience – no fancy-pants lasers or computers involved.
Total time was about 6 hours including lots of chatting about cycling too.
