with his ROTOR chainrings of some sort
Chainrings — the big gears at the pedals of a bicycle — are normally round, but there is the idea that slightly oval ones can be more efficient because they can take advantage of the naturally-strong part of the pedal stroke by placing more leverage there, and less where the stroke is weakest.
I was thinking to get some to try, but the company that makes them, ROTOR, is apparently willfully, egregiously not interested in selling them. They make a dizzying number of different models of oval chainrings, with scant information on their site about the difference among the various lines.
Every first-time buyer will have the same set of questions.... which ones fit my bike, and among those, which are right for me, and in what sizes? They leave most of this for you to somehow figure out on your own (or, failing to have confidence, just abandon the idea of buying them).
Their willfully-stupid site makes me wonder whether their products are also willfully stupid, and it should have been a sign to walk away, but I thought I'd at least ask, so I sent them this request:
It's so frustrating when a company seems to care so little about what they sell that they don't bother describing the product sufficient for even the most basic purchase decisions. I guess I shouldn't have been surprised when the reply didn't even try to answer any of my questions:
That last line was the end of it... the ticked was closed and there was no avenue to reply. Notice their customer-service email address? “email@example.com”. At least it's not “firstname.lastname@example.org”.
Wow. Just wow. Of all the companies in the world trying to avoid accepting my money, these guys really go the extra mile. That's too bad, because my friends that have them like them, though it's a mystery to me how they knew what to buy.
