Why suddenly this beautiful white Miss Cindy Cone appear at my backyard?.
In just 3 weeks I change the 'frame' of my mountain-bike to a new KONA Cinder Cone 17 inch.
All the other parts except seat-post (uno Carbon) and headset (Mortop seal-bearing) are retain.
When I bought the CUBE Aim 16", the idea was to go for off-road trail -uphill & downhill.
Only one group playing downhill at 'Bukit MCA' the rest are more into road/urban riding.
Downhill is not for me, so I follow the majority riding at night on alternate day twice or thrice a week. I'm 178cm tall, to have better handling in road ride I have to change to a longer frame, hence the 17" Cinder cone.
How to calculate the bicycle frame for you height?.
You need to measure your inseam in centimeters (cm)
(Inseam x 0.65) - 10 = frame size in cm. To convert to inch, divide 2.5
In my case: 80cm x 0.65 = 52-10 =42cm -> 42/2.5=16.8" (
17 inches)
A
cinder cone or scoria cone is a steep conical hill of tephra (volcanic debris) that accumulates around and downwind from a volcanic vent (from Wikipedia)

Here the comparison of both frames.
