My first good road bike was a 2003 R800 triple, the fancy rim with 8 pairs of spokes. Yes, 16 total.
And I did blow out the rear wheel climbing a hill. OK, order new wheels. I had set made with HD rims, 32 spokes laced cross 3. Yes they were TANKS, these will last a life time.
Point being, those wheels were much heavier, and me and the R800 lost all acceleration. The bike still road and handeled great, it just took longer to get up to speed.
So think on this when upgrading wheels!
