Hi Bikeradar!
============
On your Trek Rumblefish Elite review (April 14) you wrote: "Switching to faster-rolling rubber for some of the test livened the naturally lazy feel of the bike up dramatically for very little cost in climbing tenacity".

The RF Elite stock tires are Bontrager 29-4, 2.3" wide. Which faster-rolling tires did you switch to?

thanks
