Sounds like they live in an alternate reality when the USSR still was a cohesive entity and when cell phones were the size of bricks ??!

They think carbon is evil and carbon dust is the black version of cocaine. Highly priced! :shock: :unbelievable: :roll: :twisted: :?



Tell your buddies that if it wasn't for carbon, they'd be riding around on iron frames ;)

In the Columbus range Spirit tubing is thinner than XCr, so it is lighter.

There was a big splash for MS2 tubing from KVA a couple of years back promising to be both light and strong but I've
not seen much about it since then. Anyone know anything about it?

Here's an Alchemy frame built with it up to 14.1lbs. Not bad.

Spirit tubing is for TIG. Not sure if XCr is meant for Lugs or TIG. Weight savings mainly come from wall thickness for a given tensile strength and the use of TIG instead of lugs but only the more recent developed tubing are cater for fully TIG.

Yes, but that's only within the Columbus range of tubings.

just been thinking about my 953 frame....

there's a shim(metal) in the seatube (oversize 953) to bring it down to 27.2
it's a big shim that won't budge - i asked the frame builder if it'll come out - he hasn't directly replied to that question!
Looking on ceeway website it looks as though this shim is around 100g..
factor in paint - 100g ish?
the fact that its a 57c-c seat tube frame with a 16 head tube and 55 top tube also helps the weight
so completely bare of anything it's probably nearer 1600g or so... maybe!

I am much more familiar with columbus than I am with reynolds but I was replying to your point that stainless can be made thinner, it's not the case with columbus as their thinner steel is not stainless.

I have to admit that I miss the feel of a good steel frame. I had several Waterford frames many years ago..they were very nice. I think I'll seek out a nice steel bike for my next ride. I've always wanted a Serotta painted in the 7-eleven colors.

TIA

Depends on what you think is light...

If you want typical carbon light (1000 grams or less), you're not gaining a whole lot it durability. I've crashed light alloy and bent and damaged it...

Giant, Specialized and Cannondale all do relatively light alloy frames check out their websites. In saying that I've seen cheaper carbon frames from shops that are most lighter as well.

Thanks Charles and Irish. I wanted to get her a carbon, but unless if I can find one new from a good brand under her budget of $800.. otherwise it's alloy for her.

My old 58cm CAAD8 is 1265g, which I consider pretty light for alu.
My 'old' 56cm Carbon Soloist is only 90g lighter (1175g)!
