I'd like to replace my Rock Shox Jett C. I now ride only on the road and MUP, so I'd like to go with a rigid fork. The Jett specs are 43mm of travel and an axle to crown height of 424 mm. All the suspension corrected forks I've found say they are to replace forks with 80 mm of travel. If the axle to crown height is in range, will they do? What range of A/C is acceptable?
