Just thought I'd throw my thoughts up, since this thread was instrumental in my decision to go with the grade. I live on a gravel road, and it's about four miles to get to pavement, so my traditional road bike isn't something that gets ridden much. I have been splitting time pretty evenly between a Salsa Vaya and Ridley X-Fire. I love the Vaya, it fits well and it's comfortable, but it's just not that fast. The Ridley, on the other hand, is fast, but on rides over an hour long, my 41 year old back starts begging for a little more give, so I decided to look for something different.
I ended up with a 55cm Grade. At 5'9" and pretty evenly proportioned; I'm not certain it's the best fit, but the 53 felt just a tad small. I'm still playing around with stem length - it looks like I'll end up at 90-100mm, but I went to a 40cm bar (just my preference), and changed out the seat for an Fizik Antares VS. The other change I've made is taping up the Stans rims and mounting a set of Compass Bon Jon Pass tires tubeless. I've been riding their Barlow Pass tires on the Vaya for a while and love them. If you're looking for a great 35mm tire for any hard pack or gravel surface, the Bon Jons are tough to beat. Their only real downside is mud, but in those conditions I won't be riding this bike.
Here's a pic of my bike sitting in my office:
My initial impressions (I have maybe 200 miles on it) are that it's a pretty well thought out bike. At first I was not overly impressed with the hydraulic discs; they didn't seem to provide much advantage over the cable actuated Avids or TRPs I'm used to riding. Once things seated in properly that all changed. I love that I can now do stoppies from the hoods. I have no problem keeping up with my buddies running 25mm tires on their road bikes. My only real complaint was mentioned earlier and has to do with the wheel build. With the wider tires, it's glaringly obvious that the dish on the rear wheel is off. It's not bad, but mine probably needs to come 1mm or so towards the drive side. It might be a problem on the front too, but that's not as obvious. At any rate, I can live with it for another month or so. Once riding season is over here, I'll pull them and fix the dish this winter.
Finally, thank you to everyone who posted their experiences with this bike. This thread has been a valuable resource for me.
