Kurt - When it's a little nicer I will put the girls together for a side by side shot but this is as close as they will get for now.
The Lenton is an inch taller at the head tube than the Sports but is still riding on it's EA1 wheels which puts both bikes at nearly identical standover heights and the room in the bikepit is almost the same.
The geometry is very similar if not identical... both bikes have relatively short rear stays as they were built for a smaller wheel.
I am pretty sure the straight gauge Sports weighs less than the Lenton which is a 531 frame... before I added the fenders and swapped out the bars and brakes it was 26 pounds on the scale from the loo.
The Lenton's did not come with the lovely heron chain wheel but rather have a swappable 1/8 track chain ring on a 3 bolt spider as these were used for everything to commuting to time trials and club racing. The Lenton could have also been purchased as a three speed for a few pounds more.
The Bluemel fenders fit wonderfully on the Sports and there is still good clearance between them and the 700:32 tyres which are some run of the mill Duro Proteks... they have a vintage look and I have had good success with these tyres.
The Lenton uses the same fenders and you can see how much extra clearance there is in the frame.
I am not sure how these new parts would fit into a modern Sports as the geometry on the '54 might be just a little different, I do know that you cannot use the stock steel fenders in a 700c conversion.
And of course, because I built a fair weather and rain bike... it is now snowing.
