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.

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.

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.

I have been losing a ton of weight so that is helping, I guess my real question is should I get the 33 and use it for a while while losing weight and once the weight comes off go back to the 34, or just keeping working my ass off and deal with the 34.

thanks

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.

Old buildings, a river and bridges, and a bicycle ride to boot. Very cool.

Overlook on the Ford Parkway bridge:


The Ford lock and dam on the Mighty Mississippi:


The bridge in the background is the Mendota Bridge over the Minnesota river. I crossed this a few miles earlier before crossing at Ford:


Robert Street lift bridge in downtown St. Paul:


This was my longest ride this year, so far, and I felt great. The only problem was I didn't think to bring any food or money with me, only a bottle of Cytomax and a bottle of plain water. I was getting pretty hungry towards the end and was actually worried I wouldn't make the climb out of the valley to get back home (about a mile long, 3%-10%). I made it, but went up verrry sloowwly. Fortunately, it was overcast and only in the low 60s for temps. Next time, I'll remember to throw an energy bar in my jersey....

(I also bought a small point and shoot camera that'll fit in a jersey pocket or jacket when I'm on a motorcycle, so I've been playing with that too. )

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.

I know ,I'm so ashamed, Thanks for the info. Now I've got to see what changes I've got to make with the levers etc.

With mini v brakes you can run standard levers. For a few bucks more you can get v-brake compatible levers and run regular v brakes. You will have more choices in brakes.

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

FWIW, I've always been kinda "meh" re: Trek MTBs, but that is one sexy beast!

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. 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. He ended up in the grass and next to a barbed wire fence for about 100m trying to slow down.

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.

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. , 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!

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.


And one to keep the honey badgers at bay,
