Another Bianchi P.U.S.S. 650b Conversion - AWESOME!!!

6123 Views 16 Replies 9 Participants Last post by  Hand/of/Midas
I had seen TimT's post last week and also just happened to see a frame/fork on ebay. I built it up with mostly used parts (going back to rigid singlespeed to save some $$$ - going to sell the S-Works Epic).

Built yesterday and ridden today. This frame works very well with 650b wheels. The center of the BB is exactly 12 inches high which is perfect with my 180mm cranks. Weighs about 20.5 pounds with plenty of places to lose weight.

thats a ***** colour. :D

whats the plans for the future? Do share...
Nice bike. I like the color! Its way cleaner then mine tho. Which rims did you use?. I have a set of old Race Face 180mm cranks and the extra clearance helps for sure. Are those Wind Cutter rotors from Alligator? I just got a set myself for X-mas. Oh yea a heads up the PUSS is pretty rare so every one will know who you are!

Tim

Where are some big places to loose weight on this bike? I've got a SISS and I'd like it to go on a diet.
You should check out the weight weenies page on this site. Or http://weightweenies.starbike.com/ or http://www.light-bikes.com/
I've put mine on a diet and started out with replacing all the bolts with Ti or aluminum I also went with the Alligator Windcutter rotors and a Winwood Purist fork. Next on my list is the pedals. I will go with the Time ATAC carbon Ti.(I'm saving my $$ now) I currently use the older ATAC aluminum. I will probably stop there.

Oh no, PSpuza is on the way to being a weight weenie! Like me! Soon you'll have the weights of every part on the weightweenie listings memorized!

The PUSS was sold as a frameset only, so my build probably has little in common with yours, but I've already swapped to lighter chain tugs and ti spindle frog pedals.

Next will be:

Thomson Masterpiece seatpost - will save 145 grams
Carbon fork saves 401 grams
Ti Bottom Bracket saves 135 grams
racing ralph front tire saves 220 grams
seatpost clamp saves 40 grams
Ti rail Phenom saves 45 grams
Misc Ti and Alum bolts will save around 50 grams

That's 2 1/4 pounds of savings right there. Would take mine down to the 18 pound range.

Also a tip for a new weight weenie - I like to put all of the weights into a spreadsheet. You can sort it out by dollars per gram saved. If you're only goal is to lose weight, it would be logical to start with the lowest $/gram parts first. Good luck!

Thanks for giving me some good pointers, my Bianchi came with the Masterpiece seatpost which is nice. I really think the big problem that's weighing down my bike are the wheels and those cost big bucks. I'm actually thinking about going 69er on this bike, even more money. I better start saving!

Midas- you work at a shop right? call QBP and ask them to get you one, they will get it drop shipped from Thomson, I had to do that for a customer that needed a 27.4mm
Thomson don't list a 26.8 Masterpiece any longer. They've cut out a lot of items from their list of offerings. Some silver seatpost sizes and all silver Elite 25.4 stems have been ditched for example
Nope I'm sorry I thought it was but mines just an Elite. Does anyone know what the stock wheelset weighs on the SISS by chance. Oh and I mounted up a 29er front wheel with a 2.3 WTB exiwolf and it just barely fit on the front. I'll try and post a picture later (maybe in a new thread though cause it seems like it's hard to find a lot of info on the bianchi's)
You've probably seen this, but just in case, here is some good info on Bianchi's website:

'03 SISS:
http://www.bianchiusa.com/past/2003/site/bikes/05_SISS.html

WTB Speed Disc front, SPOT bolt-on rear hubs, WTB SpeedMaster 32h rims
I can throw my stock wheels on the gram scale sometime. I'm still riding them until i buy AM Classic hubs for the 650B 355s i have laying around.
