Ever since I got my Ridley from about a month ago, I've been puzzled by these two "soccer" balls near the bottom bracket.
There's another two directly on the other side of the bike, partially obscured by the chain ring.
There are other little numbers elsewhere on the bike, like the one below, which are not so
Yes, my bike has a clock - this is an accessory which I installed.
The problem was finally solved by worldly wise Son No 1, who said the answer lay on the other side of the bike.
Lotto Belisol sponsored a team in the 2013 Tour de France which rode the Ridley bike. Sad to say, they came in 20th out of 22 teams.
Lotto operates the Belgian lotto game and Belisol are window manufacturers.
