For the price how can you go wrong
This is my second go around with the cutter tubes from BT. The first 8 I bought about 2 years ago and I had awesome luck. I used them on both my road and tri bike putting thousands of miles on them. 2 were junk out the box but the rest took almost 2 years to blow through so that says something. Just go my second batch and so far have only used 1 with zero problems. Trusted these on my bike for IM Lake Placid and had no issues or fear of flats.
