The Specialized Borough CX's came stock on my Tricross and the experience I had with them was less than desirable. They flat a lot and pick up every shard of glass in the road. I spent lots of time picking it out and was amazed at just how easily they cut. After a couple of months I finally lost a big chunk of rubber out of my rear tire and replaced it with a Marathon Supreme. Not one flat in the last 6 months. If I had to pay money for them I would classify it as a wasted. For the money your going to spend, there are much better tire choices than the Specialized Borough CX's.
