A new fork for Leo, and reasons to talk to a framebuilder

Leo bought this frame on “the Bay” and believed it was a 650. He is a small guy and wanted a track bike to fit him. It was small. It had a 85mm head tube and the seat post had been swaged at the back to allow the use of shorter chainstays and so the wheel could slide further forward It didnt come with forks and the seller professed ignorance as to where they had ended up. Leo missed a set of 650 forks at a later auction and came to me to build him a set. Given that we were building a set from scratch there were numerous choices I could offer him and Leo decided that he wanted a sloping crown ,alla cinelli and a fully chromed fork with a threaded steerer.

My first step was to measure the angles and lengths of the frame and run some figures to decide on the dimensions of the forks. He was keen to retain the quick handling despite the fact that this bike would end up as a street fixie.When I did the numbers it was evident that something was wrong. I figured it was my calculations and decided to do a full size drawing of the frame and work backward to the fork.

At this point I began to have my suspicions, soon confirmed, that this was actually a 700 frame. I called Leo up and we met to decide what to do. I mocked up the bike with a set of forks and wheels and he stood over it. Luckily it would still be OK and we went ahead with the build.

Moral of the story. Be carefull what you buy on eBay and talk to someone who can sort things through with you

Romain’s Farleigh restoration

Romain’s Farleigh developed a crack in one of the dropouts. Given that the frame is at least 25 years old then that is not surprising,and even though Romain has it set up as a fixie,he wanted to keep it reasonably original and stick with the road dropouts.After looking at our available options for dropouts we decided that a set of Campagnolo ones would be the best. The picture below shows the d/o removed from the frame at the top with the campag one at the bottom. The other option being shorter than the original leaving little room for chain adjustment on a fixie

While I could have just replaced the broken d/o the fact that we decided to install something slightly different led to the decision to replace both.Anyway,once all of that was agreed to it was a matter of carefully removing both d/o’s from the frame,prepping the stays, installing the new ones and aligning them

All of this led Romain to have the frame repainted and after a trip to the painters and a set of new decals from Greg at Cyclomondo he was happy and back on the road
