New to Brisbane for a month

I need compact crank 34 and rear 32 in order to climb

I second that.
I might jump in this tread and ask a question if it's not too much off topic. I'm going to be in Bris on Saturday. Dropping daughter at QUT 8.30ish and thinking of bringing up the roadie and going for a spin from there for a few hours. I've heard of the 'River loop'. Any links to a 50k or so spin from the city. My old garmin 705 has a bad case of 'Failure to Communicate' so I can't load a course.

50ks - go for a coot-tha riverloop

Great, Thanks for that. think I'll do a river loop out through Indooroopilly with a side run up Cootha on the way. Should be just right. My 34/32 will get used up Cootha for sure. I'm a MTBer who's used to spinning up hills with 22/36 when the going gets tough.
