I've just got a new bike a Carrera Crossfire 2 with 700c x 45c wheels and I'm looking at mudguards specifically the topeak defender XC1 and XC11, I know the rear (the XC11 will fit as it comes in 29er size) will the front fit the size of wheels I have or is it only for 26" wheels any help would be appreciated as the set isn't cheap
