I recently tested different bike chain lubricants
following an article found on the Friction Facts website . The author
tested a large part of the lubricants on the market Performance of bicycle for Vélo Magazine using
his measuring bench. He found in dry conditions up to 3 watts of gain @ 250 watts
between the best and the worst.
3 watts is not nothing in a gain per transmission
On a 5% slope it is
practically as if we lightened the bike by a kilo! Let’s imagine a pro
who climbs @ 400w, he can proportionally save phone number library 5 watts just by choosing the right
lubricant! Enough to make the difference at the end of the stage!
So I ordered one of the best from his Performance of bicycle selection,
Gold Chain Lub (attention, found in Australia!). My test initially
will be to try to quantify a gain compared to a
degreased chain and then compared to another
well-known lubricant, WD40. I did brian haeckler information technology system compliance specialist not take the best from his selection, namely
paraffin, because I do not see myself melting it before each
lubrication.
The SRM measurement
(as for my chain efficiency test )
and so I compared each time the difference in watts measured between the 2
sensors. I chose a 10 min circuit around my home, stabilizing as
much as possible around 250w like the measurement bench. I chose however to
put a little gear (50*15 to 50*17) by turning the legs rather towards 70
rpm in order to have tension on the chain. The goal being to amplify the
losses of efficiency in the hope of measuring something! Before clean email applying
each new lubricant I completely degreased the chain then dried it. The results are below.
