Here's the thing.....Whatever bike you bring to the ride, is your choice. You can't make excuses. If you are the only SS in a group of geared bikes, so be it. It was your choice to ride without gears. Nobody wants to hear about how hard it is. Yet sometimes it's hard not to follow this rule.
Take this morning for example. I was already in the car half way to work when I got the text from the co-workers about a lunch MTB ride. Because it's cross season and because there is a cross race in my backyard on Sat (Draper), I decided to throw in the cross bike as I left the house. This, of course, meant I didn't have the right bike for the proposed ride.
I replied to the text confirming that I had "a" bike and would met up with them at lunch for the ride. I showed up with my skinny tires, 36x16 gearing, and fully rigid bike and did my best to hang with the group. I won't lie. I had to hike a bike in a few spots but managed to keep the group in sight.
The rides in Orem are steep. Designed for gears not so much for SS. And especially not for SS cross bikes. I'm not sure what was harder. The climbs or the descents. At the end of ride, I had a much greater appreciation for my disc brakes on my MTB.
I don't think anyone in the group noticed my bike looked a little different than theirs. Or at least, they pretended not to acknowledge it.
