I have a 1928 frame with footchange conversion and brake crossover bar. The chainstays on my frame are shorter than those on the later frames which means I have little room for chain adjustment. I saw several cable conversions at Abbotsholme this year – can any kind member advise me on the best and most effective way of getting rid of the crossover bar? I’m not too worried about originality, the bike is a bitza,
I’m a bit puzzled by your comments as the 1927/8 frames had longer, not shorter frame chainstays than the later frames. As your bike is a bitsa and you are not bothered about originality, I would be inclined to throw the very heavy and cumbersome crossover shaft, levers, pedal, etc., onto the shelf or under the bench, and save a few pounds in weight by making up a cable operated rear brake instead. If you look at the right-hand side mounted, and forward pivotted pedal on a standard vintage Flyer, you need to fabricate a pedal that is similar but left-handed, and pivotting in one of the “spare” holes in the left-hand frame bottom member. You can then run a well hidden cable from it, crossing over to the R/H side somewhere around the mag platform, and ending at a cable stop bolted onto the rear brake plate. The wheel can then be moved backwards or forwards at will to adjust the chain, without upsetting the brake adjustment at all !
I would use a very heavy gauge cable for the job, something like the gauge used for a car handbrake would be suitable as you can exert a lot more tension with your foot than you can with hand levers….Better safe than sorry.
PS, Brian, the frame number is 2090 (2091 is 1928 from the the records seen at Abbotsholme). I measured some chain stays at the Gathering and mine are some 1-2″ shorter than the footchange models. If you can tell me what I’ve got I would be grateful,
If you are like me and have modern bikes as well you will be ambidextrious by now, so like me you could leave your cable operating pedal on the right
NB must check out a spare Vincent rear brakecable, that may fit
I have a 1929 TT Rep with a cable rear brake conversion, lever operated by the left foot. The pedal pivots in the rearmost understay mounting bolt with a hollow centre and cable outer attachemnt lug is an extension of the rear mag bolt head.
