Bump, anyone?

You should be fine, wind is not an issue for IMBR tipically, last time I raced there (2009) I used 808+Wheel Cover without problems. Road are smooth asphalt and well maintained, the main part uses the central lane of the highway with cones separating the traffic in other lane(s) so there is some auto-drafting effect, it is mostly flat barring 3 "morros" around 3% for ~1km each which you climb going out and coming in, nice and fast course IMHO.

Hi. The wind is not very strong. The road surface is not good in 20% at least of the bike segment. A 808 will be fine. Enjoy the race! And welcome to Brazil!
