The story goes that these things were the lightest hardtail MTB frames you could buy with your hard earned drug money back in the day (something like 2700usd). I can't even remember if I saw it on here or FB marketplace, but a number of years ago one popped up for a steal and I decided I had to have it. Unfortunately I've been doing other sports and riding took a bit of a hit. But over the weekend I decided to chuck something together with spare parts I had laying around and I'm keen to get it out for a test rip.

Geo is old school 29er awful. But that might be part of the appeal, I'm sure it'll climb tight switchbacks like a mountain goat.

Scales says 9.2kg as it sits. Plenty of room to loose some weight (cranks, wheels, rigid fork?), but lets see how it rides first.

I wanted one of these badly back in the day. Super light but old school geometry. Pushys had one for a bargain but a didn’t end up grabbing it. Will be interesting to see how it rides.
Biggride still have one for $3999

I got excited and thought you had some old school dual air RockShox SID on there. It's impressively light!
Should be a whippet but I don't know that I'd want to spend all day on it, my old man body would hate me.

Old school 29er geometry just makes them very fine gravel/fire trail bikes...or quite hectic trail bikes. Whichever your preference.
 
Trails were still drying a bit here with the flood water running past town. But other than a few unavoidable puddles it was good running. If your old here and have a good memory, you'll know my local trails are all pretty much completely flat, other than some small little pitches up and down along the river bank trails. So ideal for a bike like this.

Immediately loved how pointy it was. In the tight stuff, with your weight naturally more over the front of the bike it went exactly were it was pointed. Rear end had decent compliance and felt nicer than my gravel bike through some of the rougher stuff. I run a 2.2 mtb tyre on my gravel bike so its not bigger tyres accounting for it. All of this to say, it was a bit of a rocket ship, don't know why I let it sit in the shed for so many years.

Watch me change my tune as soon as I get it on a trail that points down.

That would be pretty sick to get a hold of. These are some take off old school Fox forks I bought off a Burner a few years back.
 
I built one of these things up many moons ago. I think I sold it to guy in Geelong??
I still have one of these frames too. It's sat in a box in the UK, waiting for me to ship it over at some point?
I loved mine...until I didn't, then sold it. Much like every bike I bulid and own. Shame really.

I spy my Macgyvered open setting that I jerry rigged to not required the bar mounted lock-out switch. Definitely not Fox 32s though, I am pretty sure they are SIDs (I certainly didn't resticker them if not!) .

You are 100% correct, this is the problem when you put something together over a few years and don't look too hard. Yep they are your Macgyvered SIDs haha

My only problem with you building and selling absolute stunners every second week is you're selling L frames and I usually ride an M. Otherwise, I'm through Ballarat all the time haha.

It would be interesting to compare geo with a modern gravel bike to see the what the differences or similarities are.
