Mosaic
RT-1 ITR

The legendary Mosaic RT-1, re-imagined with 35mm of tire clearance and a completely integrated cockpit system. The RT-1 Integrated Thick Road (ITR) is designed for where we ride and the way we ride. 

Utilizing ENVE's Integrated Road Fork and a new chainstay design, the RT-1 ITR has the same intuitive steering response as our RT-1d, bringing confident handling at speed, plenty of get-up-and-go out of the corners, and the encouragement to rip up your favorite climb, paved or otherwise... As usual, this is all delivered by a particular blend & rider specific selection of double-butted titanium tubing that is infinitely customizable depending on your fit requirements, ride preferences, and build configuration.

The RT-1 ITR is completely Made to Order, inclusive of custom geometry and complete choice of Mosaic Finishwork. It's the ultimate drop bar bike.

A Note on Tire Clearance & Compatibility

We're excited to have the option to run big tires, and we know you will be too. The RT-1 ITR has optimized tire clearance for a tire measuring 35mm in actual width.

 

What does this mean? What tires can I run?

 

In testing, we found that our favorite RT-1 ITR setup of the 32mm WTB Expanse mounted on an ENVE SES 3.4 measured 34.5mm in width. This combination falls completely within the realm of acceptability in terms of tire clearance in the fork and the rear triangle. We've put thousands of miles on this setup, and would recommend it with 100% confidence.

 

Another setup we tested was the Vittoria Corsa N.EXT 34mm tire mounted on the same SES 3.4 Rim. These measured in at 36.5mm in width. This combination, although marked as 34mm, is far in excess of the 35mm measured tire clearance on the RT-1 ITR & ENVE Fork. Whilst the Vittoria Corsa N.EXT 34 / ENVE SES 3.4 combination is indeed rideable, and it's great, the clearance on this particular setup is minimal, especially against the front derailleur clamp. 

We anticipate that there will be several 34-35mm tires that depending on the rim they're paired with will not work with the RT-1 ITR, as their actual width measures far in excess of 35mm. If you're curious about the tires we've tried, and the ones we've landed upon as favorites, please don't hesitate to reach out. We would be happy to provide a recommendation.
