    Total weight - Don't know but a lot more than my epic weighed...

    Had the chance to ride a 2014 Rocky Mountain Altitude 770MSL for a couple of months mid last year and started to think about getting something Enduro to keep up with the marketing hype.

    I was in no hurry as my Specialised Epic was a surprisingly handy bike across a lot of conditions but after riding the Altitude, I realised it really opened up some new terrain to me.

    I kept an eye out for anything XL in the 130mm-150mm travel range and was ultimately looking for carbon 650B but finances dictated that was out of the question.

    When this came up on here (thanks Zaf) and looked at me with it's sexy lines and colour, I thought about it for a while (almost too long) and finally snapped it up.

    Here are some photos. More info in next post and ride report to come...

    Default the story in more detail...

    So I've been into mountain biking for about 15 years but for the 10 or so I was riding very entry level hard tail GT's and Kona's. Only really riding out on fire trails in the Dandenong mountains.

    My first real mountain bike was a Specialised Epic which has been amazing for its versatility and the amount of riding it has opened up to me. It is still the perfect bike for probably 90% of the riding I do but, as mentioned in the first post, I have a taste of what a well built 150mm bike can offer and was enticed to find my own slice of the pie while I'm still young enough to huck the shit out of it.

    Unfortunately I have neither the time nor the space for a quiver of bikes so the Epic has to go :(

    I was looking for about 6 months on here and other sales/trading sites and made enquires about a few complete bikes and a couple of frames. A frame seemed like the best idea as I could transfer across my parts that I had upgraded over time but given the fuckery going on these days with so-called 'standards' and the fact I was looking at 650b with longer travel - I was often still forced to buy wheels, forks, and sometimes any cranks. Often, by the time I added up all the parts I would have to buy it was looking a bit shit.

    Finally this came along - neither carbon nor 650b. So not really what I was after. But it came with a good deal on the fork as well and i could swap over my wheels, brakes, bars, cranks, drivetrain and dropper post. In fact, it was a massive and happy surprise to find it had a threaded bb and 30.9mm septets - same as my spesh.

    I have to say a bit thanks to Zaf who has been really open, honest and helpful with the sale. Also a big thanks to a bunch of other people on here who have traded me parts that have ended up on here. In fact, this bike was almost built by RB. Thanks to Zaf, The Azza, Rendog, Rutter, Ezkatron, Moorey, Oriion, Hard Nox, Sedifus, Topperharley - all of whom I have bought stuff off in the past. And a big thanks to Psimpson7 who has been kind enough to lend me some 20mm adaptors to get me going while a really shit LBS in Melbourne fucks me around no end on a simple part...

    Thats it for now but ride report to come soon!

    Holy shit there was some bad spelling mistakes in that previous post. What the hell is a 30.9 septet?

    So I took this massive monster out for a spin at Plenty Gorge the other day. To be honest, it wasn't the smartest choice for a first proper ride. I've never been there before and spent most of my time stopping after a couple hundred metres to try and figure out where the hell I was... Not much flow.

    The bike was sweet though. I did an ok job of setting fork and shock pressure in the car park so it felt pretty good. The Zoky has a weird bit of stiction off the top if it hasn't compressed in a while. So if you ride along a fire road then hit a trail, the first compression comes with a bit of a jolt but once it's moving, it's very smooth and so far seems to hold up well under braking with not too much dive. Will be interesting to take it to areas I'm more familiar with and see how it goes.

    The CTD shock is so different to the brain shock I was running before. I was running the brain shock mostly open so there was no transition from locked out to open. It gave a nice and progressive ramp up which gave the bike a lively feel and avoided any bottom out.

    The CTD is much more linear and seems to blow through its travel a bit. It's pretty plush though which is the obvious trade off/benefit. I would consider getting some volume spacers though to make it ramp up a bit.

    Have to play around with it a bit more too as the climb and descend modes seem to do fuck all...

    The trail 9 brakes were awesome (bring it on haters) and the fit of the whole bike with a 50mm stem was spot on.

    Finally hit some familiar terrain with the Yeti and have started to appreciate the strengths/differences of this frame and fork/shock.

    There is a section of trail a few hundred metres long that I hit often which has rain ruts running straight down it as well as sticks, rocks and roots littered across it. The Epic would get sucked in the ruts pretty easily but was so light and 'poppy' that I would sort of zig-zag my way down the trail popping back and forth over the rut.

    The Yeti can hold a line better and suck up roots etc more easily, so it's more a case of point and shoot.

    Neither is necessarily better than the other, but very different.

    I find I can readjust my line mid corner with the Yeti too. Most of that seems to come from the stiffness of the frame. Especially the fork.

    The stiction I was experiencing in the fork has lessened a lot now too so it may have just needed to be cycled through a few times... All in all, I'm pretty impressed with the fork so far and looking forward to taking it to the you Yangs one day for a real work out.

    One of the things I'm most relieved/happy about is the geometry of the frame. It has a long effective top tube but a slack-ish seat angle which a was a bit unsure on.

    I've moved my seat forward on the rails a bit and gone for a shorter stem. The result is a great seated position and a shorter reach figure than I previously had which feels great when standing and throwing the bike around.

    Still learning to have confidence in it but so far so good.

    Default The accidental 30th anniversary Yeti SB66

    Hit Lysterfield for the first time on the Yeti today and am slowly getting more used to its strengths. Can't help but feel I still need to tweak the suspension a bit to get the most out of it. I think I might be running a touch too much air in the fork and I still can't feel any difference in compression damping when cycling through the shock settings.

    Might need to take it for a service at Tekin before Brad sells...

    On the up side, this thing still eats mid sized bumps for breakfast and is so solid that I'm holding lines through corners way better than before. Could be confidence but I think it's more to do with the stiffness of the front end.

    I'm finding I need to alter my riding style a bit. I used to ride very light on the epic and take a lot more in the arms and legs. I would also pre-load the suspension a lot and pop over sections and back and forth across the trail. It was a lot of fun to ride like that but this bike is a bit heavier and the suspension doesn't pop back from pre load the same.

    I finally figured out that I just need to get in attack position and plow through. Not only can this bike take it but I think it actually responds much better to it...

    Set a few PBs and was on a gold medal run down Follow Me until I caught the group that had headed down a couple of minutes before me.

    So - a few things still to tweak but feeling pretty sweet!

    Not sure about the Marz specifically but every new fork is going to take a good 10 or so hours of riding for all the bushings and seals to wear in; after that point it should be a lot smoother. For every new fork I always do a change of oil in the lower legs after that 10 hours run in period to get rid of the small fragments of metals and whatever wears away initially.

    That bike should have plenty of pop; I suggest set your rebound full open, then slowly close it one click at a time to suit your preference. Tune the fork and then the rear shock. Many people run their rebound way too slow.

    The fork is second hand and has had oil change so I think it's probably working as it should. That said, I'll get a service in the next few months just to be sure.

    It's a good point re the rebound. I think I am running it a bit slow. The adjuster knob has broken off so I need to take a 3mm hex key with me and play with it a bit. I may also have compression a bit slow and will continue to tweak.

    Made a few tweaks and the bike is really starting to come alive for me. Took the shock to Tekin for a service and it's running sweet now. Full range of compression damping and not blowing through like it was.

    Took teK's advice and sped up rebound on the fork a little. Also took a few PSI out. Now getting full travel and feels a lot more lively.

    Went with a mate out to the Youies yesterday and had a blast. Sessioned Cressy and took a run down lactic acid and Boulder.

    The Yeti just ate it up. Felt so composed at speed and jumped really well. Hit a few doubles and landed them no sweat. Still have a few more to build up to but that's more about my skill than bike abilities. i have no doubt the bike will take it all in stride.

    First crack at it, I set personal chest runs down lactic acid and Boulder - beating previous times I set on a Rocky Mountain altitude 770 msl.

    Bought a new Yakima hitch mounted rack because the bike is massive a wont fit on my roof racks. The rack went well.

    They love to charge!
    It was the first thing I noticed going to it from my Fuel EX, it still rides the same trails that the Fuel does, but it doesn't make you want to touch the brakes, and coaxs you to hit the burly lines knowing you'll come out cleanly.

    Did Tekin identify what was wrong with the shock in the end?

    Hey Zaf, your right, it somehow feels better the faster you go. Managed to leave the brakes off through a few sections that I usually brake into - including a rock garden that usually slows me right down.
    It also loves to fly. Jumps better than anything I've ridden (not a huge number of bikes admittedly).
    Not sure what the exact problem was with the shock but compression damping was blown - I'm guessing a seal or shim somewhere in that circuit was gone. Just got them to do an advanced service and it's now smooth as butter and working perfectly. There's even a noticeable difference between the three trail adjust settings which I was a bit sceptical about.
