UltraDynamico is our friend Benedict and Patrick's tire company and these are a great choice for 650b Clem, Appa, Atlanti frames if you don't want to max out the tire size, or Sams and Platypus frames if you do. Here's Ultradynamico's description of the Rose:
The ROSÉ is our first offering and the mainstay of our line. Double it up for optimal traction offroad or pair it with our CAVA in the rear to drift the corners a bit more.
-JFF means Just For Fun, but not ONLY for fun- these tires are equally equipped for long days locked in the pain dungeon as they are for a Sunday tour of Portland's vegan doughnut shoppes.
-JFF is our most accessible offering; think of it as the industry standard in terms of casing and rubber spec. This is approachable luxury- the cubic zirconia of our catalogue.
-Handles both pavement and dirt like a skilled musician handles a Stradivarius
-Carbon compound for longer tread life on pavement
-JFF more durable casing than our RACE offerings. Fixing flats, while character building, has never been fun
-Zero sidewall protection and no puncture protection on top for premium terrain massaging ride quality
-Exotic file undertread revealed after ~1000k of use (unlike you, this tire gets faster with age)
-Continuous center tread for optimal propulsion
-Aeronautically designed delta knob pattern for superior braking traction during gravel re-entry
-Tires packaged individually in a reusable organic cotton produce sack /dirty underwear on a tour thing
-650b x 47.99mm
