i have two gear questions. first, i want to get a carbon aero seatpost for my cervelo eyre. i have found posts from some company called BP (the post is called the blade) and there are posts from u.s.e. and weyless (supergo’s company) and some company called pazzaz. does anybody else make them? i only have about $100 to spend. i’m a poor college student.
second question: i need some good solid 650 c training wheels, especially a rear one, that can be worked on. i have gipiemme tecno 404 wheels right now that are a huge pain to service because the hubs are designed really strangely. does anybody know where i can get really solid, decently fast wheels, probably with shimano hubs, for cheap? (cheap means maybe $200)
In Excel’s print catalog they have a table with all possible combinations of hubs and rims and spokes but, I don’t know if they carry 650’s. Nytro.com has a bunch of wheels on closeout. I was just looking at their site and they had a rear for $85. Before you buy an aero carbon post, you should read John Cobb’s article where he found aero posts to be slower than non aero. They look faster though which is what really matters.
For Carbon seat posts, there is also the U.S.E. Alien post, round and aero, the Easton and the new Deda Black Stick.
I have an Alien on my road bike and used to have one on my tri bike. It is a great post, one of the lightest, but is an extreme pain to adjust. I just swapped out the post on my tri bike for the new Deda Black Stick and it is awesome, probably the lightest post out there and easy to adjust. Might be a bit out of your quoted price range though. I think it retails for around $175.
I am also in the market for a carbon post for my eyre (aero or not). I posted here a few weeks back looking for one that would fit without a shim - no luck. The brand recommendations other people have given you are the same one’s I got and I’ll probably go with one of them, with a shim. If I find a carbon post (aero or not) that will fit without a shim I’ll let you know. If you find one first please let me know.
can you tell me more about shims (what they are, why they’re necessary)? i came to triathlon from a swimming background and spend more hours than i want to think about trying to make up for my lack of history with running and cycling, but still don’t know anything about shims. do standard 27.2 mm (i think that’s the measurement that’s standard. it’s something like that) not fit into the eyre’s seattube?
thanks to everybody for answering and helping me out.
yeah it’s the right address, sometimes his site dissappears for a day or two. Not often but i’ve noticed it down before. It’s worth it to check back though, killer deals.
First, you should check the diam of your seapost now. You can’t be very accurate with just a ruler (calipers work best). Any bike shop will check it for you. My eyre is from the last year they were made ('99 I think) and it takes a 28.9 post. If yours is a different year it may be different.
As far as the shim - I can’t be much help. I haven’t gotten one yet and have only had them described to me by the local shop. My impression is that they are basically a tube (aluminum I think) which goes inside the seat tube/around the seat post to make up the difference in size. I know they come in different specific sizes to fit different size posts to whatever larger size seat tube you have.
A shim is anything from the thickness of a coke can to a regular tube with a slit down the middle.
I am not a huge fan of shimming more than a couple of millimeters in thickness. That’s just me. And from the sound of the Cervelos you’re wanting to put posts into, I would find the biggest diametre I could find and go from there.
The only exception is the Corima shim for their post. It is not exactly a shim, though it does hold a device to adapt the rectangular profile of the mounting surface of the post to a round profile. I never had a problem mounting it into a 27.2mm tube.
I also have a USE alien and found it to be a pain…it also never seemed to keep its position no matter how tight I tightened it. I just purchased a Easton all carbon post but this sure has a great deal of setback. Even at my most forward position on this post I am at de3ad even with my cranks and can not get the 2cm forward post that I like. Do you know of any post that is carbon and does not have the huge setback that Easton does?
i was just over at marketplace.consumerreview.com . link up to the road bike review classifieds. under the wheels and tires section a guy just listed a set of 3 650c training wheels for sale. not sure what they are, but it says they’re like new (and they sure are cheap - $100 for all 3). may be worth seeing if he has a picture?
thanks sydnrusty. they look good and they’re shimano hubs, which are fairly easy to work on, so i can do my own maintenance on them. i just wrote the guy selling them and hope to buy them if they seem good. thanks again.
