Bike Fitting 101: Part 1

Finally finish all the bike fitting services provided by the Bike Butler. Quite an experience and educational. It allow me to pay more emphasis on my bike riding.

Why i go for it?
2 year ago, before i entered Army, was recommend to visit Bike Butler for Bike Fitting Service. Price then to me is pretty steep (even now). 100+ for Bike Fit and Positioning and another 100+ for Powerfoot Cleat Alignment. Hence, didn't go for it as I'm fine with my old bike position.

2 years later, with more positive reviews from Coach and illusion of me being more wealthy with the army allowance. I went for the bike fitting. Was so decided to get a new bike that i sold off my old ride and hoping to get one from the Bike Butler.

Bike Fit Positioning
First thing Butler did was throw me on his 'Measuring Station'. Figures shows that i had short arm short leg. -_-" sound like turtle...

Next I'm introduced to this 'AFS Bike Tool' a dummy bike jig used to assess my riding posture and my custom frame measurement.

After some body alignment... Wala! My new custom made titanium frame!


Some measurement of the frame:
Top Tube: 51cm (actual), 53cm (virtual)
Seat Tube: 44cm (CTC), 48cm (CTT)
Seat Tube Angle: 72 deg
Head Tube: 16cm
A pretty sit-back and up-right position with the 72 deg seat tube angle and long head tube.

Bike is then setup with the parts which i like, also tried to copy the theme of CUBE HPT but didn't turn out well.. Making of the CUBE

After service review & thoughts
Bike Butler have this signature mark on most of his bike. Yes~ the super long Head Tube which had invited many comments about it. Should really see my Coach ride... With the more upright position, i constantly remind myself to apply lesser pressure on my palm and work my core harder to maintain the nice curve of my back.

Leveling the handlebar and saddle height, makes the rider looks less 'garang'. But allowing the rider to sit in the 'neutral/optimal' position. Personally I'm still trying to find out more on this 'neutral/optimal' position specially on how arch should our lower back be? Tried googling it but not much findings.

Compared the Bike Butler's fitting with the US Fitting Service. Of course with more resources and support, US looks much better. They can provide video clips of you riding before and after the service. Can try go 'YouTube, Bike Fitting' as Bike shops actually uses YouTube as a media to market their bike fitting service.

Lastly Bike Fitting Service is like consulting a doctor. They can diagnose through a few tests to tell where is the problem. But without proper input from the patients, they still cant make proper judgement and prescription. E.g. Pain.. How pain? Discomfort, How discomfort is discomfort? Same for ache, sore, numb.. Especially for beginners.. isn't pressure on hand and buttock common? Will a series of tests and questionnaire help?
