Default Drive train upgrade and weight reduction?

I suppose many here have gone down this road before..

92 wicked, Original owner,

I bought a new set of wheels from Settemarche (white ti) and am going to try and put my old gearset onto this hub. I am hoping I will be able to get the gears to mount and line up properly so I can still use the SIS setting. 6 speed xt shifter. My LBS found the 13 outer gear so I should be able to transfer and space it and get it to work- however I keep questioning do I go with the rapid fire shifters and update it? I love the one on my other bike..

I Also am going to try and lighten it up in the process, the rear wheel was the stock xt 36 spoke and with the fire xc pro weighs a whopping 5 lbs. so I know I am on track with the wheels.
I ordered a new fork from Rody and will go threadless so that will drop a lb from the mag 20 21.

Is there a lighter crankset to replace the boipace xt? it needs to be strong as this old one..

Is there a lighter seat tube available? I read someone saying good luck finding a seat post that size. is it 25.4"?

I already saved 200+ grams with a different seat.

Thanks for any help,
Steve

The Wicked should have a 26.4mm seatpost, these are hard to find these days. Check out IRD and or keep a lookout on Ebay. Your XT crank is plenty light enough and it can be tough to find a crank to use with your press fit BB. My recomendo is to just get some new chainrings that aren't Bio-pace or even consider going 1 by however many you have in the back. Remember Keith Bontrager's mantra of "Light-Strong-Cheap, pick two" and remember that light isn't always better, I have had too many near death experiences with ultralight BS!

I may have misspoke. My 93 Yo and my 93 Monster both have 29.4. The 92 Wicked is smaller.

26.4 suntour xc or syncros post. both tough to find but doable. check ebay. suntour is a bit heavier. good setback and seems durable. more so than syncros.

get the suntour!

ok i'm an idiot. I pulled the seat out and see it says 'strong' 26.4

I know I will save some if not alot of weight with my new wheels, I just keep thinking I want the rapidfire style of shifter..... I guess we will see what we can do with the rear cogs when they arrive.

Also when Rody gets my fork done that will lighten it up a bunch :}

Probably not by much. You really shouldn't worry much about weight with a seatpost that is that small a diameter.

I got a 25.4 x 350 Kalloy seatpost for cheap and an alloy shim ( $10) for my Wicked. That works fine. I use a solid seat clamp, not quick release. Make sure you don't grease the shim or the post will slide!
