Shimano 600EX crankset - 52/42 replacement
My JH Wilson steel frame currently has a 52/42 on the front and 11/32 on the rear. I live in the Peak District so some of the hill climbs are a real challenge with the current setup. Does anyone know of a replacement that might make it a bit easier? A 50/34 or 52/36 etc?
I'm after an older looking solution as the bike is from the 70s/80s.
Thanks

While a finding one may be a bit more pricey than a more modern looking crank set the Sugino Maxy's took 110 bcd rings allowing for a 34 small ring and are a close match cosmetically to the 600ex.
The main things you should be looking for is a crank set with 110bcd which would allow you to run a smaller modern inner ring and iso/jis spindle tapper.

For more gearing while staying cosmetically and vintage correct you could also change to Suntour V-GT long cage rear derailleur and a wider range modern 6 or 7 speed freewheel. Which would alloy you to bic up about 30 percent more gearing while keeping the nice crank and most of the 600eu stuff. Id did this on a old Jeunet to get 34/30 low gear.

I've found that going small on the chainrings doesn't necessarily provoke comments from people unless I deliberately draw attention to them. Being able to keep up with the faster riders in the group speaks for itself.

I've "built" several compact cranks, using a Sugino double with 110 spacing, and then "borrowing" the two largest rings from a MTB triple. Visit a few co ops and you will likely find some good candidates.

+1 while this thread is getting a bit off track using vintage MTB cranks I have built gearing as low as 38/26 front 32/13 rear for short range cargo bikes.
