Hey guys! Got a nice Salsa I need to sell ASAP.

Here's a link in case you don't frequent the flea market...

Fox/Rock Shox both have about a 60 hour maintenance interval. This would be new oil, seals, and inspection normally. If you do the math that's not a lot of miles and most riders would need fork service 2-3 times a year based on the factory recommendation. From my personal experience, once a year service is a good average to shoot for.

Well, I gave in to the light and bought some SPDs this past weekend. I am strongly thinking of installing them this afternoon, and then going on a night ride with them. Maybe foolish since I have never clipped in to clipless pedals, but should be good fun!

Was it Aurelius that hooked his bike up to a machine at the shop and came away with 40% power gains going from platforms to clipless?

I wouldn't do that. You'll fall over every time you have to put your foot down unexpectedly. It's very unnatural to twist your heel sideways to free your foot from the pedal, but this is something you'll have to practice until you do it automatically, and that takes a looong time.

The power gain was 22%, which roughly matches the 20% gain other riders had told me to expect. Keep in mind also that I didn't know how to pedal properly with clipless pedals at that time; had I used the correct pedaling technique, applying force smoothly through all 360 degrees of pedal rotation, the difference might have been even greater.

OK, cool. I may not ride tonight at all. My wife may be going to her parent's tonight to visit with a sister who is in town and lives 1500 miles away. If she goes I will ride, but I may just leave the platforms on for now. Probably the more wise thing to do, I am just excited to try out the new ones. And 20% I can live with

I wouldn't go night riding. I'd go to a nice soft field for your first few trials. Because you ARE, ARE going to fall over. Would you like to do that during the day on nice soft ground or at night in traffic?

...if you choose the latter can I have your stuff?

I remember reading a fairly scientific study of racing cyclists pedaling efforts that they don't actually pull UP when they are spinning, but most of the power gains from cleats/clips/whatever is from a 'scrape the sh__ off your shoe' motion at the bottom of each stroke.

since I've started using pin pedals on my hybrid city-bike, I'm finding I get quite a bit of that going as they really hold onto my favorite walking shoes (New Balance MW956)

these pedals I picked up off ebay or amazon or something cheaply rock.

The part about not pulling up could be true at high rpms. While pedaling at slow rpms, you'll find that you can pull up quite hard on the pedals, but that ability diminishes as the speed of pedal rotation increases. When there's little resistance on the pedals, the leg pushing down will always be 'faster' because three muscle groups contribute to the down-stroke (the quadriceps, glutes, and hamstrings), whereas only one muscle group (the quadriceps) is capable of lifting the leg back up.

The part I don't believe is that "most of the power gains from cleats/clips/whatever is from a 'scrape the sh__ off your shoe' motion at the bottom of each stroke". That doesn't make sense, because the 'scraping' movement can be performed with or without clipless pedals. The only thing you cannot do with flat pedals is pull up on the pedal.

with flat pedals, the 'scrape' thing doesn't work real well, except with pin-pedals, I find it does.

It works much better with pins. Without pins, you need to angle the pedal to make sure your foot doesn't slide off when using the 'scrape' technique.

Fixed for reality

And dully noted. I'll stick to the open home sites across from my house for the first few rides (or, the falling experience with some riding thrown in for fun).

The down side to all this riding is no clients. No clients = very little $.

I'm in the 'more time than money' part of 'I have enough $ and no time, or no $ and enough time to ride' equation.

Qouting myself 'cause I'm cool like that.

And these clipless pedals are weird! I am glad I didn't go to the trails for the first ride. I will get used to them, but I think I almost fell every single time I came to a stop. Not a natural feel at all! Just have to train my brain what to do when stopping, but it will come.
