Hoping for some advice from people more knowledgeable than me about tire/rim compatibility. I am looking at buying a Grizl CF SL 7. My road bike is really old, and I’m ready for something newer, updated geometry, and the idea of a Grizl that gives me the option to ride on gravel or on road is really appealing. Admit I also love the look of it #bikeporn.

Looks like the stock bike comes with Maxxis rambler 45mm. If I wanted to buy thinner tires as I expect to do a fair amount of road biking, what is the thinnest tire that would fit, and could you offer any recommendations? The roads around me can get a little gnarly with bad weather, cracks/potholes, so not looking to go super thin as I’ll end up with punctures every week, but definitely thinner than 45mm so I feel I’m rolling and riding/climbing efficiently.

My current road bike runs on Continental Grand Prix 5000 25mm which would I think look quite silly on this bike. Maybe I’m wrong?

Here’s a link to the specs (hope linking is OK?)

  1. Nice bike, I know a couple people who love them. Thinner tires are perfectly fine, you’ll be able to go down to 28/30mm no problem. I have a second set of wheels for my grail with 30mm slicks for road riding. Depending on how often you’re changing them out a second set of wheels is a nice to have but not necessary.

    For your roads I’d recommend a 32-35mm tire with appropriate pressures. Unless you’re racing it’s pretty well accepted that they’re just as fast and way more comfortable.

    And totally up to you but if you’re doing lots of road riding maybe look into the 2x. Depending on your riding style and speeds.

  2. I got 35mm S-Works Mondo fitted on my Grizl. Rides good on road, havent been on gravel yet.
