Anyone know how much a replacement seatpost with rails would cost? Does Dahon swap this out for free anywhere? How about modifying the existing post? I want my Brooks!


I posted this hastily so it's cryptic, but for anyone else who's curious, certain models of Dahons come with this "new" technology (i.e. cheap seatpost-seat combo) that doesn't use normal rails and therefore can't accept any other saddles. It's called Ibeam-Iseat. If you're considering a Dahon I would take this into account--

No solution I know of, but I commented on this on their forums.

This seems only an attempt by SDG to try and gain market share by giving a good deal to Dahon.

Here are a couple of replacement rails for the Dahon, but they're mainly suspension seatposts. Nevertheless, you should be able to fit your Brooks:

Thanks for the replies and the link to the dahon website. Maybe I'll get out the hacksaw and torch.....I already dremeled some Cristophe clips onto the stock Wellgo folding pedals. Great bike, but needs all sorts of mods.

better yet
call me ( 800 222 8356 ) I have those regular seatpost for sale ( $ 17.00) . I am out at the moment but will receive all kinds of parts next week. ( www.thorusa.com )

Than you cn mount your brooks saddle without problems and sell the I beam together with saddle either here or on the Dahon bulletin board. There just might be folks out there who want to save some weight. as that is the main idea of specking that I beam stuff ( plus you have greater forward back adjustability )

Just out of curiosity, where is the weight saved? Just the metal of the rails? How much weight is actually saved? Thanks for the link to your site.

BTW, again, for those looking for a dahon--Brakemeister's website has good prices; on the speed 8 it's about $12 less than I paid with delivery, and I got a pretty good deal.

brakemeister

most weight is saved in the saddle, but a little in the post as well.

Its a good concept. but I wish there would be a conversion clamp available.
On the other hand the regular seatpost aint so expensive either

I bought the 2004 model before the 2005 was available primarily to get the standard seatpost clamp.

Yeah, shoulda thought of that, I was comparing the two years but didn't know what the I beam was....but I didn't like the white frame on the 2004.

Unfortunately my camera is currently somewhere in Barcelona while I am stuck here working....

I probably voided the warranty, but I just used the old-style cristophe clips that attach from the top; drilled two holes in the top-front of the pedal, and looped the strap through the webbing of the pedal, close to the outside. Doesn't work great, but better than nothing.
