Awesome Shop Bike: Bob Jackson racing trike

      This is a bike / trike that I am surprised never made it to the blog yet. I was reminded of it because earlier in the week a similar trike came to my attention offered for sale on central NJ Craigslist. My size even! Here is a link to the listing. Bob jackson trike craigslist

      The above photo is of the one for sale (no affiliation to us).
  
     Ours is roughly from 1974 and the shop has owned it for close to 15 years. It is left hand drive, set up for British roads. Below is an explanation of the difficulties one can encounter riding such a set-up on American roads / tracks.
   A single-sided drive trike -- especially a British single-sided driven by the left rear wheel -- presents problems, (or let's say potential challenges) to an American riding it on the right-hand side of the road. A left-side driven trike, in Britain, would tend to push one up out of the shoulder of the road surface toward the crown of the road -- a good thing -- compensating as it were for gravity and road surface. However, the opposite is the case if ridden on the right-hand side of the road, where the machine would tend to pitch one down the camber of the road into the margin, so that, to stay out of the shoulder, one would be constantly correcting against the mechanical impulse of being driven doward. With a one-wheel drive you're correcting anyway, but if you're also correcting for having a "wrong-side" drive, it's much more pronounced. 

     While I am not an expert on all the details of trike differentials, a differential will help compensate for the difference between the two rolling rates of the the rear wheels whilst turning and so provide better tracking around the bends. As you no doubt know, turning at speed on a trike is a tricky business to begin with! (taken from an email on the CR list regarding British trikes in the USA)


 Ours is built from Columbus tubing, of note is the dual front brake set up and the unusual front brake cable hanger that mounts to the stem clamp. another detail at the back end is the use of Bottom bracket cups for the rear axles and the indented chain stays (as if a single rear wheel would be used !?). Very cool / rare piece that needs to be ridden more. Enjoy the photos!

Awesome customer's bike: Early 1970's Pete Matthews

     This bike belongs to one of our best customers. He recently acquired it and brought it in for us to assemble / service.  He rode it for the The Great British Bike Weekend that happened over the weekend here in Philly. It is an early 1970's Pete Matthews. Mr. Matthews is mostly known for his wheel building skills and gained a worldwide reputation for his very lightweight and durable wheels. Here is a link about his work. Pete Matthews
     The bike pre-dates him taking over Jim Soens bikeshop in Liverpool , England by about two years. The owner estimates the bike to be from 1970. it is a very nicely constructed road bike with eyelets for fenders (common on British bikes due to frequent bad weather). It has nice long lug points and elegant fully wrapping seat stays. Not to mention the nice sunburst style pinstriping on the fully sloping Cinelli fork crown. Also of note is the modified Campagnolo front derailleur. The clamp band has been thinned (filed) and drilled. It is also an early version with the bronze arms. The cable stop has also been cut off and filed smooth. This bike rides great and when test riding it, I imagined it would be a perfect bike to do a century on, quite comfy. Enjoy the photos!
