1" carbon forks upgrade advice

[bg2]

hi

i have a steel Gios frame from the early 90s that i use for road and club riding often.

It has some beautiful chromed threaded 1" forks, with a cinelli 1a stem, cinelli bars and a campag headset

however, this is all rather heavy!

Being a regular bike, i'm looking into making a massive weight saving by going 1" threadless with some carbon forks.

I've seen a few options on wiggle and various other internet stores.

just wondered if anyone has any advice or experience with this?

p.s. before someone mentions upgrading wheels and gruppo first, it's already done!

Well of course you will need also to move to an Ahead setup. So it's forks, stem (plus 1"-1"1/8 converter shim in all likelihood) plus a headset.

I have done a similar thing with my 1994 Litespeed. It's not difficult but is definitely more involved.

You don't necessarily save loads of weight - I put 1" carbons on my Donahue - threadless, with ahead stem & shim - will try & load some pics later...
Maybe saves 150g or thereabouts (or about 1/10th of a full water bottle)! I'm really happy with the ride, but I was before too - I only really changed because the old forks were not that attractive, whereas chrome forks on a Gios just seem right don't they?!
1" carbons are not that widely available - you can get some threaded ones for quill stems - Tifosi I think. Also try Ribble's clearance/2ndhand PDF. Mine were from Bike24 in Germany. Things like ITM Millenium & Look come up on eBay. I know I have a pair in a shed I never used - carbon with aluminium crown a can't remember the brand.

really?

columbus carbon forks: 360g
steel forks: 650-900g(?)

quill stem: 280g
threadless: 160g

bars: no idea

seems like there could be something in it.

Are you sure on that weight? I couldn't see published weight for 'Minimal' when I was shopping around - but 360g are normally about £500 not £160! If so, great, but it's more likely 485-500g (hence saving of 150g on decent steel fork). It's a lovely looking fork whichever way - one of the nicest looking carbon forks.

Here's the Donahue too:

I bet that is for 1 1/8" forks with a carbon steerer. There were a few originally but as far as I can see anything new is ALU steerer and 500-550g. Probably 1" carbon steerer tubes were a but marginal anyway...

Re:

Oddly enough my wife's bike went in the opposite direction. The figures which I weighed at the time were 450g for the ITM Millenium Carbon (there were tons of 1inch carbon around I had some on a C40 and also have a spare set of 1 inch Colnago Force that my Master was supplied with. Intergiry no issue), 670g for the Gios Team. So 220g saving.

I had my eye on these: http://www.wiggle.co.uk/columbus-minimal-road-forks/

Apparently 329g

Re:

They are nice - trouble is the 1" is out of stock, unfortunately. Although they are coming back in at some point I'll need to keep an eye on that I may snap some up myself.
