        provides "ample breaking" every time :-P


        Yeah pretty much the same as the one above, hey?


        Rebel sport have a 50% off on bikes …. $500 down to $299, better than what the Deliveroo riders use and look at the mileage they do without carbon frames or Ultegra, or Deore or Lycra, …. get in quick now O-bikes are gone from melbourne.


    Hi op, how does this compare the Polygon T8?
    I've been eyeing off the t7 and T8 as an upgrade from my Aldi beast.

    Haha, my 1998 Marin Riftzone just turned 20. Still not managed to break it, most likely as that year actually shared the same swingarm as the B17. A few upgrades over the years to give 100mm travel/front but the fundamentals have never been changed, even the swingarm bearings are original. It still runs v-brakes but given they're by Avid rather than Shimano they still work fine in dry conditions. I've got other bikes but this is my basic goto. It's had a long route starting in San Francisco, via the UK, Switzerland, the French Alps and now Sydney….

    The whole range has got a bit lighter over the years but still a solid contender, just not common in Aus. Marin have always been a reliable brand IMO.

    My advice with Mountain Bikes is go for something as simple as you can, with standard parts and a consistent history e.g. Marin, Giant, Trek, Specialised etc.


      Nice. My first MTB was the 1998 Alpine Trail. It had a ghastly cro-mo swingarm but with the same front triangle as the others. I coveted the next models up for their alloy swingarms but just couldn't afford it at the time. Marin single pivots were always way ahead of their time. Canonndale copied it some 6 years later, look at this bike and tell me it isn't a 1998 rift zone with different decals lol… https://www.feedthehabit.com/mountain-biking/2003-cannondale...

      That was always the best part about Marin bikes, they all used the same frame throughout the range. So even if you bought at the cheaper end of the range, you were getting a top of the range frame. So you could over time build a genuinely top of the range bike just by changing components. But that has changed now. boo.

      My favourite bike was a 2001 Wolf Ridge. That was peak Marin single pivot, before they went 4 bar "quad". USA handmade 3VH front triangle (same factory and front triangle as Ellsworth bikes costing 4x as much) and a beautiful solid CNC machined yoke on the swingarm, and same with the BB/pivot housing. 9-way adjustable shock mounting. It was such a nice bike to ride. I wish I had kept it.

      My last Marin was a 2004 Attack trail. I still have that frame lying around.


        I remember the Alpine Trail - I decided to go the next one up i.e. the Riftzone, it was the US version so had a Fox rear shock. Cost 1550 USD. At the time my local bar, the Marin Brewery had a 97 Riftzone hanging from the ceiling.

        Over the years I also acquired an early 90s Marin Ultimate, allegedly ridden by Paul Lazenby but who knows. It had all the high-end boutique gear, e.g. ceramic rims, Pace cranks, XTR and Titanium Hope hubs. Sadly the frame cracked bombing around Parramatta Park - just need an ex-Russia aerospace welder to fix that up…



    Seems pretty heavy 14.5kgs

      Pretty standard weight for this price point and spec.


        At the discounted price yes


        I actually just picked up a new bike today, carbon frame 12.4kgs with fox all round, sram gx for $3199. So if you know what you are looking for there are some good deals out there


      Its got 27.5+ tyres. Marin frames are usually at the lighter end of the scale. My last one was a 2004 Attack Trail and I built it into a 12.0kg 6"x6" with a carbon Pace RC41 fork. These are also true four bar link bikes, or at least they used to be. Looking at the photo of this one its hard to tell but it looks like its could be a faux bar link. hmmm.

      EDIT: yeah it is faux bar. The Marins further up the food chain are proper four bar like they should be.


    What's with people riding bikes with ridiculously large tyres these days? I saw this guy today that appeared to be having trouble riding his bike on a flat road because the tyres were as wide as a cars!


      ahh the sand (profanity) …. bikes designed for the sand …..hate to think of the rolling resistance on the road ….

    Mountain Bike - $3,499

    You'd think for that price, they'd include the pedals…

    • +2 votes

      yes, even $1000 bikes should come with at least cheap pedals so you can ride the thing home and then swap over to your nice ones or decide what to buy next ……it’s like selling a car without an accelerator pedal …are people supposed to supply their own or not drive the car home …..


      …still waiting for this to be funny

        usually when i get a new bike i take the train or tram to the shop to pickup the bike and then ride it home , only option if you don’t have bike racks for your car, or a car big enough to,take a bike.

        seems dumb that i need to buy them as extras to get the bike home ….and extras have higher margins than if supplied at the factory as std ….. or bike shops that don’t want to keep cheap $5 pedals ….
