I will write again when there will be new ones :-)

Colle Agnello is one of the highest BIGs and it is a very hard climb from the italan side.
The video is here:

I uploaded 2 videos about cycling Passo Stelvio from Bormio.
That's a true bicycletouring video and was recorded just the following day, when I and Mauro repetti cycled Trittico Mortirolo.

Here you can find all of my other videos about climbs going above 2000m.: http://www.gyorgyigabor.hu/GYG_osszes_hago.php
I will go on with uploading new ones.

Up to now I haven't found bicycvling video about this climb on the net / web.

Now, I have one - I can suggest this to show, how hard it is:

A partly rainy day: first in rain cycling up to the hardly known ascent above 2000m, Champillon (in rain) (2078 m),
then the BIG: Col du Gr St Bernard (2473 m) - mainly by sunshine:

Rare video about Rif Gardeccia ascent + Pasmpeago & Zischgalm (2000 m), but before that the video stats with
Passo Gardena and Passo di Sella . It was cycled on the 20th of May, 2011 with snowmeadows along the road.

Total 175 km + 3848 m heightdiff.

This video contains 2 BIGs and the remaining ascent is the most beautiful: just under the MOnt Blanc under blue skies: Val Ferret.
BIGs: italian side of Col du Petit St Bernard (2188 m)
(than Les Suches, 2200 m)
and than Colle san Carlo (1950 m):
