It's been a while since I last posted, so here are some updates:
The Seat Concepts is finally broken-in, and on a ride of 400km in one day, I had no more problems.
I had my AirHawk with me and I didn't need to use it, which says a lot
I feel is 100x times better than stock :O
I have almost 10k km on my Michelin Road 5, both front and back, and both seem to get close to the end.
I'm surprised, I liked better the Road 4, and not only the back had a better life (about 11k, compared with 9k) but the front went for almost 15k...
I'll try the new Road 6, they say it last 30% longer. And as usual, I'll be changing the tires myself
