Hi

Hoping for some help as i am looking for a new bike for upto £600, i am looking for a good all rounder so i can commute on it and maybe do some events on it, not bother about mud guards or rack.

i have found a few in my size (58cm) just not sure which is best

I have looked at each bike and just wondering if one stands out from the rest as all the specs seem similar? will i notice the difference between sora and tiagra?

If there is a bike i have missed please post it! will need delivery though as on isle of man lol

thanks for any help

When moving up a groupset the difference between most groupsets is usually quite small, the main exception is the move from Sora to Tiagra, the Tiagra is significantly better, especially the shifters. Having said that the Tiagra chainset on the Cube is Octalink which is pretty much obsolete (they must have found some old stock lying about). To me the Cannondale looks to be the best of the bunch.
