Good commuting tire. Thiis is a decent quality tire for commuting where you don't care so much about flat protection, but want a good value on a tire. This has a raised tread square tread pattern. Great deal in an inexpensive package. +
Bike Friday bikes can be built with either 451 and 406mm rims. Both sizes can be referred to as 20" wheels, when the 451 is a larger rim. Confirm you have a 451 or a 406 before ordering by looking on the side of your current tire to confirm the rim diameter.
