One example is my "new" Specialized Roubaix. It's a 2010 model, which features the former-generation Shimano 105 shifters. This unit has the external shifter cable, while the new Shimano components have all cables integrated internally, then routed under the handlebar tape.
I must admit that this shouldn't matter, but it does. I'm not fast enough to be anything special, yet hold some perception of who's on the latest equipment. I'm not.
Another cosmetic issue that popped up was the fact I always run a frame mounted tire pump on my bikes. But when I bought the Specialized, I opted to get the new CO2 canisters for tire inflation. Why? It's not cool to run a pump on your frame. Not the look of fast dudes.
But over time, I had a change of heart and mind. I'm not fast and won't be able to get faster. Additional training and more weight loss may get me 10% but that still puts me off the back.
So, I love my bike, irrespective of the external cable shifters. I bolted my pump back under the water bottle cage. I'm a goon and that's what it has to be. Life is rolling past and I have to live within the parameters God has offered.
