Sign up. To be honest, there's not much between a lot of downhill bikes on the market, but the two that you're considering really are at opposite ends of the spectrum in terms of what they each excel at.

Let's look at the Demo first: it's a nimble bike that is going to take less effort to ride and race on tracks that require a bit of pedalling or are less fall line in their layout, and it's a load of fun on smoother, jump filled trails that really allow its playful side to come out. Depending on the terrain, it's also one of the best cornering downhill bikes on the market, at least in my mind, thanks to its relatively short rear end and low bottom bracket height.

If the Demo is the gazelle of downhill bikes, the Gambler has to be the lion. The Scott has a much larger presence on the trail, and while a solid rider is going to get it down any course in good time, it feels most at home on steep, chunky and fast terrain. It also sports adjustable geometry that allows you to tailor it to exactly those sorts of tracks, letting the rider slacken it out much more than what's possible with the Demo, and really feels at home on the gnarliest of trails.

Where it doesn't excel, at least in my experience, is on tamer terrain that requires you to use some ponies to keep your momentum up. It's a serious bike that performs best on serious trails. I'd recommend that you make an honest evaluation of where and how you ride before laying out cash for either. I'd tell a downhiller who rides and races on more average terrain to go with the Demo, but the Gambler may be more up your alley if the only pedalling that's required on your trails is the twenty feet from the truck to the trailhead, which really isn't how it usually is.

Sometimes the gazelle is fastest, and sometimes it's the lion. Take the chain off the front sprocket and spin the crank. If it spins smoothly, you can eliminate the possibility that you blew up your bottom bracket bearings. Next, view the rear derailleur from the back of the bike to see if it is visibly bent inwards. If not, the most probable reason for your rumble is that the rear derailleur's B-tension screw is not turned in enough to keep the upper derailleur pulley from running into the cogs.

The B-tension screw contacts the hooked tooth of the frame-mounted derailleur hanger. Turning it in clockwise rocks the derailleur body away from the cassette sprockets. Another problem that is specific to one-by transmissions is running the chain too short, which draws the lower cage pulley so far forward, that the angle the chain creates between the pulley and the chainring is greatly exaggerated when the transmission is shifted to the extreme ends of the cassette.

This causes rumbling at the chainring as the links attempt to engage the sprocket teeth from an odd angle. The new chain and cassette may have tighter tolerances and thus would naturally make more noise.

Check the B-tension screw first and then set your chain up as long as possible. Start by stringing it through the rear mech with the derailleur shifted into the smallest cog. Set the chain length so that the pulley cage just begins to angle downward - that's the longest that the chain should be.

Finally, you did not mention whether you were using a short, mid or long-cage rear mech. If you are using a mid or short-cage derailleur, it may not have enough chain takeup to cover your gear range, in addition to the amount of chain growth built into your rear suspension. A drivetrain with a perfectly tuned chain length on the bike stand may be pressed to the breaking point when the suspension is sagged or compressed while climbing.

You may need to bump up to the next longer pulley cage if this is the case. Bottom bracket 'standards' can be confusing, since the number of different options continues to grow. If your cranks are already removed, the easiest way to tell what you have is by measuring the spindle diameter. As the name suggests, a BB30 or PF30 crank will have a 30mm spindle diameter, while a GXP crank's spindle will measure 24mm with a 22mm splined portion on the end.

If you look at your bike, the bearings for a BB30 setup are typically found inside the frame, while the bearings for a GXP would be housed externally in cups that thread into the frame. Another way to find out without doing any measuring or crank removal is to go to your bike manufacturer's website - there should be a section where all of the frame specs, including bottom bracket type are listed.

The-dirt-farmer Aug 19, at Bottom brackets are one of those areas where I wish every manufacturer would agree on one standard, and stick with it. I would also be nice if I could afford Scott but life is tuff haha. Enduro27 Aug 19, at And that standard should be an external cup threaded style.

Yea, the bike manufacturers could even test out their new ideas for BB standards to see if they work before putting them into production? Then, for example, if they were considering using press fit BBs on their new frames, they would find out that they last around km before needing to be replaced and then they might reconsider putting them into their frames. Barkit Aug 19, at Enduro27 : Amen.

It will be interesting to see how many props are given to Enduro27 and ka-brap's statements. I wonder how many it would take before manufacturers woke up and took this seriously. Of course I also wonder when I will win my state's lottery.

Unfortunately, I have never "played" the lottery but I suspect that both events are just about as likely. Reinforcer Aug 19, at IMO press fit bb is one of the worst and most offensive changes to bikes ive ever seen. Also press fit bb, from what ive seen, can creak like hell and often they dont last as long nor are they re-install friendly.

I can understand if cheaper models came with press fit but when someone buys a 6, dollar bike with a press fit its just and insult to the cycling community. A year ago there was a wheelsize poll that saw maybe 10k total votes and while the most votes went to the 26ers for life option, pretty much every brand that hadn't gone to B already has now done so, which goes to show you how much brands actually listen to people here ie, not at all.

Fielder Aug 19, at So sick of replacing my drive side PF30 bearing every month on a bike. Pick a bottom bracket standard and be a dick about it. Again don't let whiners on this site who have time to complain fool you into thinking that there is any sort of majority against it, because the developers of these bikes are riders, and they're not against it, nor are their customers, nor are the vast majority of high end road bike customers, or bmx customers, or jump bike customers Pinkbike users speak for no one in the industry except themselves, because the industry honchos long ago came to the conclusion that this isn't the place for mature discussions, its the place for showing off eye candy or commenting on stuff as if its just there for the user to fantasize about.

For examples of that ridiculous behavior by pinkbike members, i suggest you start following the posts of Amanda Batty, as a female DH racer she gets all the immature sexist abuse this site is known for. Literally try your absolute hardest to fabricate a single benefit to a press fit bb other than manufacturing cost.

The benefit was explained in another article quite nicely a few days ago I bought a new carbon stumpjumper in April with press fit BB. In under 18 months I have been through 8 or 9 BBs. I have also had to send the frame back to spesh twice now because the BBs have seized and started spinning in the frame and worn the carbon away. It's been re-appoxyed both times to make it a tight fit again. This is my first bike with a press fit BB, and until now I have never had a problem with the old screw-in external BBs.

The guys in the bike shop tell me that they're all experiencing the same problems that I am. Thats not the fault of press fit bottom brackets per say, that's a problem with the construction of your particular frame.

If you have to epoxy the thing into the frame then the tolerances were pretty shoddy. Case in point the whole fiasco with ISIS bottom brackets. There does seem to be something wrong with he construction of the frame in this case, but the frame has failed twice in the time that the BB bearings have failed 8 or 9 times I've now lost count.

There have been 6 or 7 times when the frame has been fine but the bearings alone failed. And the frame is only failing because the BBs are seizing in the first place.

You can tell me over and over that there is no problem with the design of this press fit system, I will never buy another frame with it and looking at the way the different comments on this thread have been propped, I know I can't be alone.

A frame with for example a miss-alignment in the dropouts where the hanger cants inwards slightly even with new derailleur hangers, if the part of the frame it attaches to is out of whack, then you're pretty pickled will always be miss-shifting and also prone to putting the chain into the spokes.

As to the way comments are propped on pinkbike Bike designers long ago gave up taking this site's member opinions seriously because the vast majority who bother to complain about something don't represent anything but the whacko fringe of the sport.

You spend a lot of time commenting on and reading these comments for someone with so much contempt for them. I really don't see how the frame could be out of alignment - I have no problems with my shifting and you would hope that if spesh had gone to the trouble of re-appoxing the BB, they would make sure it's done straight.

I have contempt for ignoramuses, idiots, and morons of which this site plays host to many. Frames usually don't "get" out of alignment during usage without a crash being involved but they often come that way brand new out of the shipping box.

The epoxy specialized's dealer used to re-install the BB was a bandaid solution to avoid having to warranty the frame. The site is full of conspiracy theorists and cynics Of course what do I know I've only mountain biked for almost twice your age, and have seen practically every bottom bracket interface ever tried. I'll play it when its appropriate.. When Race Face was pushing hard for the ISIS standard and Shimano wouldn't play along, we all thought Shimano were being dicks and greedy and not wanting to play fair.

Then we all forgot about ISIS and were really impressed with the innovation Shimano brought to the market. We don't hate new, innovative things. We hate change for the sake of change, moreover change that brings about a poorer product.

If not, then you clearly have no idea about how many customers are actually affected by this. It really sucks. When this design was first pioneered in the road bike industry, it worked pretty ok because it's obviously a different type of riding with less abuse on the products involved. Now that this design has been brought to the mountain bike world, it really sucks.
