This was the one treat I allowed myself at Stalen Ros. A Campagnolo Veloce 39-53 crankset. It was being sold off because people want compact chainsets, now. They have been a boost for climbers, but the rear cassettes have become the bane. I thought gearings were poor enough back in the 70s. It is even worse, now. Gearing has become the abandoned aspect of bike set-ups. People ride with 30 gears, but can only use ten. And bikes are being sold with 53×11 combinations because that is what professional riders in the Tour de France pelotons have – as if the average rider, even with training, can make that combination turn around.
I rarely get out of my small chainring – a dated 42 – but I rarely get dropped from training rides; not because of high speeds, anyway. If I keep this 53, then I will look for a 16-27 cassette. This is radically far away from the standard today. At the low end, a 39×27 is so easy to turn over for a sportif rider. Even then, I might look for a 50 tooth large ring to make the ride smoother at the top end. You can go quite fast on a 50×16. And don’t kid yourself. It is faster to spin a 50×16 than grind a 53×11.
Flat blocks, combinations that change one tooth at a time, are a godsend, and yet harder and harder to find. You can make subtle changes in your cadence and keep a far faster ride overall, especially on hilly circuits. But people insist on, or get sold, a jarring, widespread combination they can never use efficiently.
If you want to do yourself a favour, look for a cassette with minimal changes between rings. It can be as revolutionary as better wheels and tires. Junior racing cyclists are limited to 52×14 combinations. It used to be 50×15. I would ride the latter, if I had my way. I used to hold near 40km/ph for 40 kilometre time trials and would regularly race a 50 kilometre criterium in an hour. Take a look at your riding and speed and just spare a thought. Do you really need town gears you cannot use? Do you need anything larger than a 52×14? Next time you replace your chain and cassette, consider something flatter and easier. You will be faster.
