Just thought I'd share a few of the recent modifications I've made to my 2014 Fuji Absolute 1.5. Two things prompted me to make these changes. First, I was looking to decrease or eliminate the numbness I've been experiencing lately. And second, I wanted to make the bike a little more trail-worthy -- specifically, to give it more grip in loose material like gravel or stone.
I changed the stock grips (Oval brand) to
Ergon GP1 grips. The Oval grips were good at absorbing vibration, but they were a little too large in diameter. As a result, I think they were pressing into my hands too much and cutting off circulation. The Ergons fit my hands much better.
I added
bar ends to give myself more hand positions. I wondered whether they needed tape as well, but I decided to try them bare first, and I'm glad I did -- no tape needed.
And finally I swapped out the stock 28mm Vera CityWide tires for
35mm Schwalbe CX Comp cyclocross tires. That is a wider tire than what Fuji told me could fit on the bike, but after measuring all the clearances myself I was convinced they'd fit. And they did indeed. I've read many times on this forum that tires make a big difference, but still I was surprised at just how much of a difference they made. The combination of gaining 25% in width and lowering the pressure by about 50% smoothed out my ride on the bumpy, cracked country roads around here. And today when I hit a short stretch of loose stone, I could immediately notice the improvement in control. To be sure, they're slower on climbs. But it's worth it to have the comfort.
In order of what made the most difference for the numbness, I'd say the tires by far made the most improvement, followed by the bar ends. The grips help, too, but I don't think they're as big of a deal as the other two things.
I'm attaching a few pics to illustrate. The first shows the original tires for comparison.
