Four-time world champion Franco Marvulli will be joined by Swiss countryman Tristan Marguet, German Marcel Barth and Austrian Andreas Mueller at today's pipe-opener for next week's major carnivals.

Cycling co-ordinator Rick Martin said he had spoken to the four overseas riders and explained to them the trickery of the tight Rosebery circuit.

``It's probably not much different to some other flat tracks they've ridden on, although the surface may be a bit rougher,'' Martin said.

``But when it's all said and done they're top-class riders who know how to keep out of trouble.''

The overseas cyclists are the first to ride at Rosebery since American Bobby Lea won the wheel race in 2004 and their appearance today will give the carnival an enormous lift.

Martin said the four Europeans had arrived in Tasmania last Monday and Marvulli had offered their services to ride at Rosebery.

They will stay overnight on the West Coast at Tullah Lodge and plan to ride the 160 kilometres back to Latrobe tomorrow as part of their training regime.

They will be joined at Latrobe within the next few days by world madison champion Kenny De Ketele, from Belgium, and Denmark's Roy Pieters.

Exciting Sydney 16-year-old Jack Edwards will become the latest contracted rider for the carnival series after he was promoted to the scratch mark. 

Martin said Edwards would be offered some money from the budget to mark his elevation to scratch.

``It is inequitable for one rider off scratch to receive no money compared to the others,'' he said.

Martin said funds had become available following the non-appearance of Adelaide scratchman Alex Edmonson.
