Carbon kallineb!

Cyclingnews'i andmetel on oodata carboni ja seega ka rataste ja juppide kallinemist juba sel aastal.
Põhjused on suht proosalised:
...However, there's a global shortage of carbon fibre, with composites factories all over the world having to cope with rationing of the fibres that go into making carbon fibre. This is due to the expansion of the Chinese economy, the building of the Airbus A380 and Boeing's 7E7 Dreamliner, top-secret US air force projects, and the proliferation of windfarms across Europe. Every windfarm blade of 50m or more is made of carbon fibre. Shorter blades can make do with cheaper, heavier glass fibre....
Samas on artiklis ka hoiatus selle osas, et carboni nappuse/kalliduse tõttu on osa juppe nn "võltscarbonid", st väljast carbon aga seest nt klaaskiud.
...The first consequences of the forthcoming price hike can already be seen, claimed Dr Weng. He said his R&D team have come across Asian bicycle components made from cheaper glass fibre, 'wrapped' in carbon fibre. Last year's trend was for carbon fibre sheathing over aluminium cores, a shady practice but one that's easily proved to be taking place (so long as you can bear cutting into your 'carbon' handlebars, that is). However, glass fibre cores can be dyed to look indistinguishable from the carbon fibre outers and it needs specialist testing to spot the duds.
Dr Weng said consumers should be made aware that carbon fibre bikes will not be coming down in price any time soon and that cheap-as-chips carbon parts and frames may not be all they seem....
Lisaks saate teada kust tulevad Giant'i ja lähitulevuikus ka all-italian Colnago carbonraamid.
