I took my 8 speed bike to the French alpes this summer. The picture is from 28. July and there is about 1 km to go in 39/26 on the Alpe De Huez.
8 speed was not the trouble, I just have to do more KMs next time or maybe get me a compact chainset.
The chainset used on the picture is a 10 speed Record Carbon ultra torque, it works fine with 8 speed without any mods.
