I have had a Cannondale Caadx 105 for a little over a year now. I am very happy with the bike and having a lot of fun.
I have started to get very comfortable on the bike and I want to take my riding a small step further by making my ride a bit more agressive ie. removing the 3 spacers which will lower my position about 1-2cm. Any tips or advice on this? Will I end up with immense back pains or is this quite allright to do?
Second thing is wheels. I am using the stock Maddux rims which I estimate weight about 2.2kg in total or there abouts. I am torn between Shimano Ultegra or Pro-lite Bracciano. Any opinions?
Thanks for the experience and expertise I don't have
