I put about 3,000 miles on my Endurace before giving up on it. It is a very nice bicycle, but the frame was just too stiff for me, so the ride was not comfortable enough for my beat up body. Otherwise there was no problem. Well one problem...the bike uses a 1-1/4” steerer tube, so finding a different length stem can be a bit of a challenge.
I had no need for customer service other than a couple of minor presale questions regarding conflicting specifications between models on their website. My questions were answered with several “I thinks” and “probablies.” This was not confidence inspiring and as it turned out the answers should have been “No”.
