I bought 'em, and figured if they worked, great. If not, I'd put 'em back on Ebay, and go from there.
I bolted 'em up to a set of Force compact cranks, using the standard 50/34 gearing. I run an 11-23 cassette in the rear almost all of the time.
I also live in AZ, so we don't really have any major climbs around the city. I push bigger gears, and lower cadences.
I don't know if the gains were psychological, or not, but these things work! I went up a couple miles of hour on our modest climbs, and found I was dropping my friends on hills I struggled with before. For me they were a "secret weapon", and luckily no one noticed I had put 'em on.
Not to be rude, but your account is pure anecdote. I really doubt the rings are making you go a couple miles an hour faster. Ride them for a year. Keep track of your power numbers, climbing speed, then report back. BTW, there are plenty of major climbs near the valley. EOP, Bartlett lake, mining country loop, Mesa to Payson. I won't even bother with all the big mountain bike climbs. PM me if you need to know where to ride near the valley.
Not to be rude,but did you even read my post before you started typing? Look at the part in bold. I said it may just be in my head, that they worked. I did notice a slight gain after installing them. Just because they didn't work for you, doesn't mean they don't work for me.
I adjusted my FD, and they shift fine. Did you try to adjust yours, or just bolt 'em on and hope for the best?
See the part in bold italics, I said around the city, not around the state. I live out in the east valley, so Usery to the beeline is about as big as I have time to do.
PM and I'll tell you where to go, and what to do when you get there.
