i plan to run the shock so stiff that the BB pivot wont matter, i had a kona DS back in the day and even that didnt pedal so bad, its only got 4 inches of travel, cant be that bad.
could be, but if they work they work
isn't it a bit odd to buy a full squish bike and run the suspension so stiff it's basically a hard tail?
it is, and it feels weird, you can feel when the suspension compresses that the guide moves and pulls the chain, its there and it keeps the chain on, but it feels terrible, this frame should not be ran with gears IMO
yes and no. if you run it too stiff then yes its uselss, and this is super relevant with a 4" travel bike, if one runs it too stiff, it will compress on landings but it is so harsh that you dont even notice it i.e you might as well be on a hardtail, you end up taking the majority of the impact with your knees anyways just as if its a hardtail. this frame should still be ran with 15% sag if it were me.
I know your probably going to think im just ragging on you again, but if you want a DS 4X jump kind of bike, i really suggest you look at something else, not taking away from it as its a great jump/play bike, good for someone with only 1 bike thats rides dj's, some trais, and overall playing around. For someone that already has a hardtail and a 6" bike (yourself) i think you would benefit far more from something a little more dedicated to the race side of things with slacker geo and a better suspension platform. such as a spec SX, yeti 4x, intense tazer.
because your chainguide and chain will move whenever the swingarm moves. look at your DH bikes, the tabs are on the the main triangle, not on the swingarm.
yeah, but that doesnt make sense? On my (insertDHbike) i pedal around the lot and it works fine, whether i am on a slope a flat or a downslope. Now the killswitch keeps the chain in the same spot as a DH bike when its not compressed, right? For me, when i land a drop and compress 9 inches the chainguide stays still, but the chain now comes in from an angle it "shouldnt". The killswitch compresses like the bike "doesnt compress"
it keeps it in the same spot when its not compressed, yes. but when you compress the suspension on the Killswitch, it will move the chain and guide because it is rotating with the swingarm thats around the BB.
i fully understand that, but since the killswitch is concentric, the chainguide will move 30 degrees(factual number) but so will the derailur, chain and cassette, so shouldnt this become really good in that sense. its all attatched, so although it moves, it doesnt move against itself like a DH bike does.
exactly, you have to imagine, being a full suspension bikes, that compression happens from both end with you floating in the middle, this cause both ends to move "up" while you remain constant, the guide on the killswitch will also move with compression, combined with a spring loaded derailer, this will create tension and relaxation in the chain (chain growth and shrink) thus you will feel your feet being pulled by this. on a regular bike, the guide remains constant with you, keeping the chain where it needs to be, on bike with unusual wheel paths this is why a pully has been incorporated in some designs.
Has pinkbike ever disliked anything before? What are the chances they will say (anything) sucks, this bike isnt worth the money, it rides like crap. I highly doubt they will, because if they do, they will no longer get free stuff to test. Not saying i blame them, but i have yet to see pinkbike slamming products.
When I worked at REI they gave us stuff to test and review, but before we could put the review in the magazine the company had to look at it and approve it. I don't think you are allows to simply say "this sucks."
yea it moves in conjuction with your drivetrain (because its mounted to the swingarm). but picture it this way: when you are NOT pedalling (landing a jump, through a turn, etc) the chainguide will move and your cranks will not.
Why would that matter? At worst its a 30 degree variation putting growth in your chain comparable to say... 2-3 link lengths, if that. I think you'd notice that about the same you'd notice chain growth while your downhill bike is cycling through the travel.
the only scenario I can think of is that since the lower roller on your guide is changing position (rotating clockwise 30°) in relation to your front triangle and cranks (assuming the situation I described when your not pedalling) it might generate some pedal feedback
Is it an irrational concept because you dont want it, or cant afford it, or is it an irrational concept because i can provide more uses for it than you can? is this the same deal as the 831 (that you now have) Cant we just play nice
wouldn't a BB mounted chainguide not solve the problem since its a concentric BB and the front triangle is surrounded by the chainstays?
I may be totally wrong here, but im thinking that this would be better than the normal DH bike, it might look weird having the guide "move" but its moving with all the components that would normally create the problems, this should be good?
it would be the same thing on this particular bike as mounting it to the ISCG tabs.
Agreed, but now the issue is the top guide's clearance with the frame, and/or the pulley giving you some kind of pedaling response. Both of which, I think Blck Mrkt would have noticed early and made efforts to fix.
I have seen them with chainguides on them, so my guess would be that they chainguide doesnt smash the frame anywhere, that seems like a something important they would check.
i am playing nice, i dont see any part of my previous comment that was supposed to be negative, it was a general response that can be applied to any sort of consumer good, just using your case as an example.Is it an irrational concept because you dont want it, or cant afford it, or is it an irrational concept because i can provide more uses for it than you can? is this the same deal as the 831 (that you now have) Cant we just play nice
