It's much harder to find good options in 38mm vs. 42mm, unfortunately. Neither size is as popular as I'd like though!
The Rene Herse Babyshoe in endurance casing measures a little smaller than in lighter casings; about 39.5mm on A23s for me. I will take your word that this is too large for the rear, but if there's a chance it'll fit, it's a good option: I find the endurance casing to be very robust, tougher than a lot of casings that flaunt their flat protection. Another option I can suggest is the Teravail Cannonball 650x40 in 'Durable' casing, very tough tire with a fast rolling tread. I'm not sure what it actually measures out to; might fit both ends of your bike but I can't put money on that -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
