Dig your enthusiasm
santambrogio. With 9 months of training ahead of you, 41-28 is plenty low. Super Record with a 28? Maybe. If this is your first time, go stock OE. This will be my 5th one and my plan will be the same one I always use: get strong enough to ride the whole course with a 52/42-13/24. I’d hold off on using cleats on unfamiliar training courses. When you can do the dirt and climbs with clips and straps then try the cleats.
edit: my plan hasn't worked yet but I always have a blast.
