Colango Extreme Mark’s Colnago original drop out failed. It seems to be a design fault as we have received a few Colnagos with drop outs cracked in the same place, the same way. Drop out has been replaced, Mark is back on the road. Share this:TwitterFacebookLike this:Like Loading... Related August 17, 2015August 17, 2015 by London Carbon Repairs Leave a comment
