Nice to see that you're doing your research, DackRider!

Both the Muirwoods and the Codas appear to be excellent candidates for your cycling needs. The only real difference that can see, would be tire width. The Muirwoods have a tire width of 1.6in (40mm), where as the Codas have a tire width of 32mm. Tire width becomes a factor when it comes to both speed and surface impact.

The Codas, having 32mm wide tires will perform better on paved surfaces, in terms of speed, that's why they're considered as "Performance" hybrids. Essentially, the Codas are flatbar road bikes. Of course, they can handle the lightly wooded trails too. OTOH, the Muirwoods would be better appreciated not only on pothole riddled streets, but on root riddled trails, as well. What the Muirwoods lacks in speed, it compensates for in road tenacity. The Muirwoods are more like rigid forked hard tail mtbikes.

Simply put, one is more speedy than hardy. While the other is more hardy than speedy!

I say, test ride them both on typical terrain, and go with your gut feelings, before you pull the trigger!
