Not trying to beat a dead horse (or in this case a dead seat clamp. ), but technically speaking the only real way that your brother could have stripped the teeth on the clamp is either if the clamp was not tightened properly over time or if it was defective.

I agree that it's a smart thing not to let others ride your bike, but I think part of the reason why you never noticed the issue beforehand is that you have a different riding style than your brother (as in, he doesn't have one just yet really. ). If the seat bolt was loose it can cause the teeth to grind together and may eventually cause it to fail. You probably never noticed the issue since you tend to stand up over bumps. Him sitting on it caused the problem to show up sooner. After the first time the seat started to nose down and you tightened it the damage was probably already done.

Not trying to go back and forth with you on this either; I agree that it's a smart thing not to let others ride your primary bike, but give your brother the benefit of the doubt on this one, that's all.

BTW what seatpost did you have anyways? On my bike it came stock with a carbon fiber/alloy seatpost from Ritcheylogic. I'd bet a 10 dollar bill that nothing short of an angle grinder could wear down the clamping surfaces on mine. Can you post a pic of the seatpost?

It was the stock one Alloy Micro Adjust Bootless Suspension 27.2x350mm switched it for a kalloy one.

Size 60cm bike, Mavic pedals, size 48W shoes... Nobody could ride my bike

I could ride it, shoes too probably.

Mine is 63cm CAAD9 - the biggest they make.
And I ordered a custom frame from Italy which is even a bit bigger.

I'm happier with the custom frame by the way. If you shop around it doesn't have to cost too much and getting the fit dialed in is way worth it. Maybe not in the first 60km of the day, but definitely over time it's great to have a good fit.

Getting back to the original topic though: having the fit dialed in is another good reason to not let someone else ride it. They'll tweak this and that, and even if you thought you had measured it it's not easy to get it all back to your fit.

I'm going to try and find a 63 Frame over the Winter, swap all my parts and then sell my
frame.

A funny equipment swapping story:
Seattle Cross Club runs a Valentine's race called Heart-Braker. The first year I decide to race it, the format was "TBA". So we all sign up our teams and get to the race venue only to be told that each two person team will trade off laps on the course, using one bike between the two racers (hand it off like the "baton" at the start line.)
Teams were already picked, so teams like mine with huge height discrepancies were at a distinct disadvantage. My teammate couldn't swing a leg over my 62cm frame without busting his nards, and I felt like a circus bear on a mini-bike riding his 54cm frame.
Top that off with his bike having different pedals; so I'm left scrambling about trying to find someone to trade shoes with who happens to 1. wear my size, 2. have the cleats I need, and 3. need the cleats I have! Astonishingly, I found someone exactly like that within a half size.
So I raced that day on someone else' bike which was 8cm too small, while wearing someone else' shoes which were a half size too small.

That is signature worthy lol

You do realize that you are still on the losing end of this argument. I am just over 350 pounds and ride a variety of bikes, mostly road bikes. Because I am so big, I generally do not stand up when I hit bumps. My seat post clamps have never gone out of adjustment except for when I forgot to tighten it down VERY firmly. You just might not have the hand strength to tighten it down all the way. I understand you are upset at your brother and are trying to blame him by rationalizing his lack of standing up for bumps but that isn't the issue, the issue is an improperly tightened down saddle clamp.

You avoided the issue by standing up for bumps but that doesn't mitigate the fact that the clamp apparently wasn't tightened down enough. Because of that you are blaming the brother and I think that is unfair.

On top of that, seat posts are cheap. You can get a new seat post for around 10-20 dollars for a decent serviceable one. You shouldn't let the bike languish in the garage just because of a saddle clamp problem. Go to a bike co-op in your town, they will help you get a new seat post for super cheap or help you fix the current one with the hacksaw trick (I like that idea!). You should get it fixed at a co-op for under 10 dollars.

While realizing that this is an old post, I wanted to compliment you on your generosity. There are good people in this group, and you are certainly one of them. Thank you.

I wear 48W's and here's a pic of my last road bike............






Don't worry though, I won't ask to ride your bike or borrow your shoes if we ever meet.

donalson

how big is that thing? what is the bb-sadle top length?... I really like that super long head tube... as for shoes... I squeeze into a 47... bet a 48 with proper socks would fit nicely

IAMAMRA

I don't know, and now that a bit of time has passed so has my feelings on the matter. I was able to sell off some stuff to buy a new post(was about $20). The new one is working great, and very happy with it. Never heard of a bike co-op, but sounds interesting.

bobotech

Ahh, missed that the original post was older. Anyway, look for a bike co-op in your area. They are run mainly by volenteers who help people work on their bikes and teach them how to fix them. They also have a supply of cheap used parts and most all tools needed to work on bikes.

We charge an hourly rate for the use of a stand and very reasonable costs for the used parts.

She was a 27 incher from BB to the top of the seat tube, I sold it several years ago. It was a sweet riding bike but I was spending all my time on my MTB and needed garage space. Not sure what I was thinking, I'm really wishing I had it back now...

donalson

wow... just how tall are you?... with a frame like that I could actually have the bars high enough without stupid stem work...

Murray Missile 

I'm only 6' 1-1/2" with a 34" inseam, it was actually about an 1" too tall for me, I could just barely clear the top tube when standing on flat ground. Ideally I rode a 25.5" road frame but I got such a good buy on this one I couldn't pass it up.

For some strange reason, I almost never get anything returned in quite the same condition it was loaned out
