Which saddle (brand, shape, etc) are you suggest to me? My legs are not tired after 40-50km but the sitting is not so comfortable (I use cloths).
And pls tell me about the differences between wheels and tires. What can I gain with a better wheels and tires? Originally I bought the bike with Bontrager R1 700x23c.
My main goal to is to keep 30km/h for a long distance. Therefore I train every day, I ride 42km. I have a good track/route. A little uphill for 20km than turn back.
I agree with others on the saddle. If you don't like the stock one, it's an upgrade that you can actually feel. Personally, I love Fizik Saddles. I have the Arione, but they have several different ones that have different attributes. That said, there are many premium saddles that are quality, so you may want to visit a shop and test a few. Every body is literally different and what you prefer may not be known until you test them.
Bontrager tires are fine, but if you want more flat resistance, you may go for something like the Continental GP 4000S (the black chili compound version). Bontrager makes a "hard case" tire that will give you good flat protection, but the ride won't be as good as the Conti.
