    The bike is a 08 Look 566 with 175mm crank. I guess I should have done some more homework on the gearing. The bike came with 12-25 which at that time, I could not use. Just too fat and every time I when out, I just knew I was going to have a heart attack. Change to a my current 12-27 without having to go to a longer cage. Really works great, but even with the weight lost ( 50lbs so far), I am still around 230Lbs.

    I to have had 3 trip under the knife with my knees. ( football, baseball, dirt bike riding, ect.) rode hard and put away wet as they say. I keep looking at gear ratio like a motorcycle. One tooth in the front equals 3 in the back, but based on your numbers, it is not quite the same. Was just trying to take a little more strain off the knees. I do use the big ring a lot more now on the flat and small hills, so maybe not is all lost.:D

    No reason to spend the bucks for such a small amount. But then again, I spend more than that to change out the cassette. Based on the numbers and how I am riding now, I may run out of gearing on the flats with the small ring. Oh well live and learn.:D

    Thank you for your help

    Gummee. Yep they do make a 33. Not cheap and made only of Ti. I am not that big of a weight wienie. Using Ti on my bike is like taking a sun chair off the Queen Mary and bragging about how much lighter it is.

    1-tooth difference in the front is gonna get 'lost in the noise.' 1 tooth in the back will help more. Going to a 28t big cog isn't gonna mean new derailleurs unless ya want em. Bigger than that and you'll need mtn stuff. You *may* be able to get a mid-cage to go 30t, but I'm gonna bet that its iffy. I haven't tried it with my D/A 7700 9sp mid-cage rear derailleur...

    Shimano? Wanna sell the 25t cassette? Trade for the derailleur (assuming you're running the big S)?

    Re: mini v-s. The reason they went 'mini' is so you don't have to change out the road levers on yer cross bike. Nothing but the cantis get switched out. HTH

    Sorry no. I have it mounted on the Fulcrum 7's that came with the bike. Hope to build a bike for the wife someday. Currently running the Wilson's 30x on the Look.

    But thank you for the offer.

    33 vs 34 in the front is almost imperceptible. get a bigger cassette in the back and will make far more of a difference.

    34/27 is 1.26:1
    33/27 is 1.22:1

    34:29 is 1.14:1
    34:32 is 1.03:1

    (29 and 32 being typical larger cassette lows)

    do check your rear derailleurs max low gear and max difference... The max difference is (big front + big rear) - (small front + small rear), in your current case (50+27)-(34+12), or 31 teeth. You can often push these numbers a couple teeth but caveat emptor.

    re that '1 in back is 3 in front', that works when your ratio is 3:1, but at the lower end of the ratios, its not nearly as accurate. with extreme granny gearing (less than 1:1) in fact the opposite is true.

    I didn't skip riding today.
    But, I was a good boy and did not force anything funny deal is that I took it easy with the headwind today and made to my usual marker about the same time I always do. I turned around at 33 minutes figuring I'd get an hour in.

    Got home in 54 total. And I stopped to put my floppy tire sock in my back pack because it was bugging me flopping around tied to the seat and seat post.

    I don't feel too bad, so I'll ride tomorrow as well. Maybe get to sneak in a ride on Sunday too.

    Belt? Belts are for road bikes, You've evidently never ridden in Ohio's premier wet clay!

    I'm not investing in all new running gear when I know what's on there works

    Turned out to be not quite 60mi with a few of em on a gravel road. Moorsomethingoranother Rd up to the top of the hill, then back down and back to C-peper. Rolly vs hilly. :clap Still managed to get up some stinking hills.

    One 'ohmydoG' moment as we were horsing around sprinting. There were 3 of us. J takes off and M and I watch him go for about 100m. M takes off with me on his wheel. When M catches, J starts to swing wide to keep him off his wheel. What J didn't see was me sprinting around the outside as he was looking over his right shoulder. J kept drifting over... and over... and I finally hit his left bar with my right elbow when I ran out of road to my left, sending J into an overcorrection and at a ditch. HowTF he managed to keep things upright, I'm not sure. :scratch He ended up in the grass and next to a barbed wire fence for about 100m trying to slow down. :eek1

    The rest of the ride was pretty uneventful. We were 3-man pacelining for a bit down one of the roads outside Rapidan, VA. Fun times that. Pacelines are SO much fun. :ricky

    I had a nice uneventful ride this afternoon. After spending the morning motoring around the Inland Empire looking for stuff. The REI used gear sale was on today so that was a zoo. Did not feel the need to buy anything after the sight of the first wing of the checkout line. Internet here I come.

    Splitting lanes for 15 miles to get home sucked.

    I got in an hour and a half down the good old river trail. I kept my head even when people came by, I resisted the urge to spin up and grab their wheels. Good thing, the skinny kid on the fixie was doing about 23 mph.

    Yeah, I did pace him... Began catching up too. :evil, but thought better of using up what I had left in the tank so early on the return route.
    It turns out that was a good thing.

    As Paul Sherwen would say, I turned myself inside out to get up the first, then second steps and that final step I dug deep.

    As I rolled into the hood, my clocked ticked over 1:35. Nice!:clap

    I managed to average just a teenie bit under 15 mph so I'm happy with that. I even stopped for some snaps,

    The weather today was as near perfect as it gets.

    It was beautiful here in CT today as well. 42 miles with the killer hills. Going out tomorrow for 55+, with less humidity. First flat this year today,at the bottom of a 42mph hill! Could have been scary!

    Sunday ride, 58 miles. Going to put a big dent in the couch this afternoon!:deal

    You and I should head up to Danville one weekend. They are supposed to have a nice trail system that parallels the River. I know the MTB trails up there kick ass.

    On another note, I placed 2nd in the Powerade N.C. state games crit today. Got away with 4 other riders and lapped the field a few times before drilling the sprint. :clap

    I bought my 6 year old son a Raleigh Rowdy (with 20" wheels) kid's bike yesterday. Scored it used on CL for $40. It has a 1x6 speed gripshift with Shimano Journey derailleur, Tektro brakes, Suntour forks, Cane Creek headset. It is 10 times better than the hand me down, taco wheeled, Mao Mart POS he has been riding for the last year. We went out to the local nature park today and rode for 1.5 hours on the paved/gravel roads. The boy got the hang of the grip shift in a hurry and was making me work to keep up on the flats, as he spun it out in sixth. He was smiling the whole time. We covered at least 12 miles. What a great Father's Day.:clap I've been waiting years for this.
