Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

very offset seatpost

does anyone know of a 40~45mm setback seatpost in 31.6? all I find is a Ritchey WCS and I'm not really looking forward to buying a $250 post.

thanks...

Really.

Even a larger frame can only do so much. Remember we're only taking maybe .5 degree difference in seat tube angle when you go up a size... if any difference at all! Notice the saddle all the way forward on this bike with the seatpost shoved all the way in there.


A frame with a more relaxed seat tube angle, however, could do the trick. But in either case, a $250 seatpost would probably be less expensive than a new frame. Look for older Easton posts, as some of them had long setbacks, although not as much as 45mm iirc.

they don't make this frame any larger, so that's not really an option. and I'm not going custom. I could probably get away with a 35mm offset, but I would like the extra room and to not have the seat forward on the rails.

If you want more room, why not move to a longer stem?

Those are both terrible suggestions that probably won't achieve proper fit. If I tried that, I'd need knee replacements soon!

Tough. Face it, you're a freak with weird proportions like me. Be happy if you can attain the correct position on a 25mm setback post and just ride.

Stem length has no affect on hip position in relation to the bottom bracket or knee angle.

Longer stem or bigger frame. Pick one and go with it.

Proper fit is a range of things based on bike geometry, comfort, and what you want out of the fit. People have different bikes with different setups that both fit. It's a dynamic thing and not a static thing.

You can keep the knee angle and extension pretty spot on if you raise the post and move the saddle forward, and like BT said, stem length doesn't affect your knees.

The OP said that they like having more room in the cockpit and a longer stem can help achieve this.

Just my $.02. I'm not a fit expert by any account.

I went to get another fit this weekend and the problem seems to be my femur length and the seat tube angle. we tried going to a 130mm stem to accommodate, but he didn't like the position it had me on the bike. I need to go rearward on the bike about 20mm and run a 110mm stem, which I'm currently using. Ritchey makes a 45mm setback, which will work, but I've never used or no anyone that uses their products.

Not only are they the lightest, but I have found them to be the easiest to adjust and disassemble for cleaning.

The Europa is the best seatpost I have used.

the Ax Lightness is listed at 345euro, which comes out to 520.00$ dollars.
i said the LOOK post was expensive, but i suppose it's all relative.
i stand my ground. the LOOK post is a solid one bolt design, and how often do you clean your seatpost anyway.
520.00$, you've got to be kidding me...

I don't kid. Ever.

If it rains, I clean my bike. If I rode on or through something that isn't a paved road, I clean my bike. If it's a recovery ride day and I have a hour to spare when I get home, I clean my bike. Just as everyone with the tools and the know-how should too.

My saddle cost $600 to have made, and it's lighter than the seatpost.

WW-ism is as serious as it gets in terms of cycling beliefs.

Training wheels are training wheels.

$400 that lasts 10 years is worth more to me than $2000 that might not.

Although correct, the saddle position does affect the hip position, and the suggestion was to get a longer stem instead of a further setback seat. Your own comment proves me correct. If you need the saddle further back to get the correct hip position and knee angle, a longer stem would not achieve that.

See above. I'm also no pro fitter, but suggesting a longer stem to someone who wants his/her saddle further back makes no sense for the exact reason you claimed (stem length doesn't affect your knees).

If the OP just wants a longer cockpit, a longer stem may be the answer. If s/he needs the saddle further back, the stem won't help any.

As someone who needs his seat pretty far back, I can tell you that getting a longer stem and leaving my saddle too far forward would only cause knee pain. I say this with painful personal experience.

Sounds like me. I search out frames with laid back seat tubes. Most big names out there don't cut it, and I'm currently on a Tsunami, which has a 73* seat angle for a 55cm size. I'd love to find a 72 out there, but racing bikes with laid back geometry don't seem to exist.

You can get FSA K-Force seatposts with different amounts of setback. The one with most setback is listed at 37 mm: https://www.fullspeedahead.com/fly.as...duct&taxid=116

Ah, sorry for the confusion.

I was confused why the OP wouldn't just move up the seatpost till the femur was accomodated. Raising the post would provide additional 'setback'. This would shorten the cockpit, hence a longer stem to the OP's preference.

I understand that you two have long femurs (urban and OP), but I can't understand why raising the seatpost isn't an option as that will give more leg extension.

Fill me in, what am I missing. I'm honestly confused as to why this isn't an option.

Truvativ single clamp seat posts have 40 mm of setback. You can get them as XR, Team and Team carbon. Check eBay. There are usually a few floating around in various diameters at good prices.
