Hiya , are these Carlton's ok ? , saw one today looked in good shape and original , could be worth resto if it's worth doing
Nice geometry so nice to ride despite not being a featherweight. became the Pro-Am 12 when it got 12 gears.

Funny how what was then run of the mill mass produced nothing special is now seen as some sort of classic.
The giveaway is the parallel geometry, literally a corner cut in the design to make the build cheaper at the expense of the ride.
Would a non-parallel frameset be better? shorter wheel base and so forth? I think the differences would be negligible, unless the rider is some sort of pro.Funny how what was then run of the mill mass produced nothing special is now seen as some sort of classic.

A genuinely good quality frame has the angles in proportion to the size of the frame, eg. a steeper seat tube for a smaller frame. A smaller frame may also require an adjustment to the head tube angle and/or trail in order to give toe clip clearance. But varying angles means more work to build. Using the same angles for every size of frame is a cost cutting measure that you'd only expect to see on the less expensive models.
Pubrunner, frame material is no guarantee of quality, back in the day loads of really cheap and nasty 531 frames were made, be they massed produced in factories or built in people's sheds.
Shaun, nothing wrong with parallel angles as such. If 75 parallel suited the rest of the dimensions of the frame then that's fine. My point is about when they use the same angles irrespective of the other dimensions.
