shims or posts?
My new bike build is almost done.....I need a seatpost....a 30.9.....
Now I have several 27.2 laying around....so my question is....
Should I just buy the shims or adaptors which will allow me to use my 27.2 seatposts.....or should I just buy that 30.9...
What are the pros and cons of the Shims.....
- will it damage my frame/Post
- am I secrificing any strength
- would the shims cause any slippage, needing frequent seatpost adjustments?
- are the generic shims accurate in terms of sizing...
here is a sample of what I am considering

Must be a Specialized, eh?

What are the pros and cons of the Shims.....
- will it damage my frame/Post? No.
- am I secrificing any strength? No.
- would the shims cause any slippage, needing frequent seatpost adjustments? None that I've ever detected.
- are the generic shims accurate in terms of sizing? Should be.
I got sick of the 30.9 deal with my old BigHit and went to a shim and a 27.2 and never regretted it.

Thanks
dminor, gastro, and FreeRidin' ...
its A Haro V5 frame....
I have a couple of Kelloy UNO seatposts. that I could use with the shims.... the cost of this would be around $10 for me.....
but I was eyeing on some Estong EA70 and Thomson Elite seatposts.....cost probably $50
what am I going to get for the added $40? any thoughts.....
thangs again guys...
Once I put the seatpost on....I have to find a digital camera to take some pictures...
and I will probably come back with "what digital camera for All Mountain bike pictures? under $XXX?"...
you know that digital cameras that take XC bike pictures are not as sturdy as the AM digitals....

thanks for your suggestions Pete. the seatposts I was refering to worked for me pretty well. never any problem. But, I am kind of venturing into the obscure world of All Mountain riding (I have no idea what the heck it means)...but still going with the AM flow....
here is my current set up so far....
Frame: Haro V5 18"
Fork: Manitou Splice Elite, I am going to give it a try. If it does not work I will put my RS Tora 302 (used)
Cranks: Shimano LX M 572
BB: Shimano
Wheels: Mavic XM317 with XT 765 or Sun Black Eye with Deore Hubs (thinking about putting the better wheels on my Cinder Cone 2005)
Brakes: Avid BB7s with 160mm rotors
Levers: FR-5
Pedals: Kona Jack
Tires: IRC Backcountry 2.25 (thinking about putting a Pana Cinder up front)
Shifters: SRAM X.7
Derailleur (Front): SRAM X-Gen
Derailleur (Rear): SRAM X.7
HeadSet: Cane Creek S-8
Handlebar: FSA FR-270 (1.5" rise)
Stem: FSA FR-200 (90mm/6º rise)
Cassette: SRAM PG971
Chain: SRAM PG951
Grips: Generic Lock On grips
Seatpost:**********
just wanted to sare this. I know its kind of juvenile ....but, I still get very excited when I put together a bike and ride it for the first time...even at this old age of 30....
