Would you bother?
What are Ralph's like in the damp/wet summer showers?
(Have NN's on now & been given a RR, but debating whether to buy another RR (all UST))
Best of both if you are uncertain, RR on the back and NN up front is a popular combo. That is what I'm running and liking it.
Throw a RR on the back and keep the NN on the front. An excellent and light combination that I ran last summer and am again this one.
Personally prefer Racing Ralph on the back and Rocket Ron on the front
Have used RR 29er tyres throughout the winter. They are not great on mud but grippy on hardpack and do pretty well in the wet.
Ridden RR all winter.... was surprised how good they stood up to all the crap 😉 diff get them on for the summer... so fast in the dry!
I've never bothered. NNs are good everywhere.
Depends what you're doing. If it's going for that last bit of weight loss and speed then RR front and rear would be better. If not then stick with NN up front and RR on the rear. I'm currently using rocket ron up front and RR on the rear which is fine.
