Customer feedback
“The Lightning shifting was actually better (with Stronglight Zephyr rings, 50/36 and Red FD) than it was on my Campag Ultra torque non-compact set-up: shifting between rings was a little quicker and I never dropped the chain off the inside, which happened very occasionally with the Campag.” — Graham B.
“When I spend a good deal of money on something, my philosophy is that I had better see and feel a difference right away. That’s exactly what happened with the cranks. Straight away I knew they were so much more efficient and faster. The first ride was a 30 mile out-and-back ride. I know all the time checks at the various points and know my best times there. At the 20 minute mark I was 1 minute faster. At the 30 minute mark I was 90 seconds faster. At the 15 mile turnaround point I was 3 minutes faster!
“I averaged 19 mph at the end and I think my best average before was 18.3. All this without trying to hammer and go faster. I guess the efficiency and weight savings did it all. So far I have done 3 rides and am amazed each time I ride it. It feels like I have a continuous tail wind. One of the cat 3 dudes tried to shake me off his wheel twice going to the finale and he couldn’t drop me. I was holding on without too much effort. Just amazing! My hat’s off to Lightning. Thanks.” — James
