Malaya - glad to see you got on the Carnegie website, they're probably one of the largest and best equipped racing clubs in metropolitan melbourne.
You might also want to try posting on http://atta.asn.au/bb/index.php
- the board isn't used so much over the southern summer, but someone might pop in and help you out. If not, try contacting the Australian time trial association by email through their website http://www.atta.asn.au/
- their contact us page might help.
Other people to contact might be:
(they have a forum if you can't get in touch with someone from the club)
(they're a shop, not a club, but talk to them about putting you in touch with the local Tri clubs, they're possibly the best connected shop in Melbourne when it comes to the Triathlon community - Anthony there is a nice guy)
- A local coach, not many of his members have TT gear but he's a nice guy and may be able to help you out.
- Another local coach, deals mainly with juniors but again has a few clients with TT gear.
Hope that helps - unfortunately the TT scene arround here isn't that fantastic at the moment.
