    The DHR requires a high seat eh?

    I'm a happy owner of the 08 DHR, and so is my GF, but we don't find it perfect. (No such ting as a perfect bike I guess...)
    The frame construction requires the user to run a pretty high seat, if you wanna avoid your tire to hit the seat. This I find a bit annoying and my gf hates it, and it actually slowes her down as it takes away her freedom of movment while riding. I'm 5'10" on a medium and she's 5'2" on a small.
    I'd like to lower mine a tad, but I can live with it. My gf however needs to get something done, so hence this post.
    We've allready swapped the seat to a turner xc, which has a low profile and "tire-hole" in the back. We've moved it forward a bit, and adjusted it higher and higher as it still keeps skrubbing her tire while landing hard on jumps and drops. This suckes for her, cause now it's to high, and the tire still hits it. (We're both running Maxxis 2,5" for the record).

    I've thought about getting a shock with a shorter stroke, like a 9,5x2,75" or something, but that's not an easy find. An option migth be to add a nylon spacer on the backside of the tiny bottom out bumper on the stock fox shox.

    Any sugestions ppl?

    Happy to hear from you

    Oh, I guess I was a bit unclear in my op, so I edited it a bit.
    The problem is the tire hits the seat while bottoming the rear shock.

    For what its worth this happens on my small Highline too, although I'm fine with the height I end up needing. Its probably much more of an issue on small frames, because the linkage is the same but the frame is much more compact and the rider is shorter (and therefore wants and needs a lower seat). I've definitely had a few times where I had the seat a bit too low and got that loud buzzing/thunk on the first drop. I need to expose about 4-5" of post to avoid that.

    You could try sliding the seat all the forward on the rails. What kind of post are you using? Most posts have a certain amount of layback built in. You could try a post like a Thomson, which has less and will push the seat forward a bit.

    Wow! I didnt realize this was an issue. That might be a deal breaker for my gf looking at a Highline. If she cant slam the seat down, then it isnt much use to her! Almost ALL of the riding this bike would see would be on the Shore, and for that the seat needs to be slammed.
    Dont know where to turn to now.......

    My wife is 5'4" and has a DHR as well as a HL. The seat/tire interference is an issue on the DHR but not the HL, at least for her. She runs a Thompson w/o any layback on the HL and has slammed her seat nearly all the way down for dh runs without any seat buzzing. The DHR is another story though. It is tough to get all that travel on a small frame without the seat getting in the way. This has only been an issue in very steep nasty terrain where she has wished for a bit lower saddle height.
    I have heard a rumor that the small DHR will be receiving a shorter seat tower tube to move the saddle forward and help correct this situation.

    I should add that I'm using a WTB Power V saddle, which is pretty big. And I'm fine with the saddle where it is, even in very steep terrain. I just have to remember not to put it down all the way.

    Here is a pic of my bike with the saddle at (or very near) its minimum height.

    Thanks for the pic Jabber......that would not be low enough for the type of riding we do! Yes, a Power V is a big saddle ( I have one on my RFX). Perhaps with the right seat, it would be doable as 1SR says. She occasionally bottoms her XCE on the Shore, but I dont see her doing it all that often with something with 3+ extra inches of travel

    Cheers

    I dunno, we have some rollers around here that are damn near vertical and I've never felt like the seat was in the way. For me, its more that I'm so used to just slamming the seat all the way on my dirt jumper that I tend to do that on the Highline too, which then causes the tire to hit the seat on hard hits.

    We definitely ARENT sitting while riding! The seat needs to be slammed so you can get back far enough over the rear tire to stop yourself from going over the bars and taking a big dirt snack. The stuff up here on the Shore just isnt very forgiving if you get it wrong.....

    Keep in mind the Highline is a compact frame w/ great standover. This means that the amount of seatpost exposed can be misleading as to actual saddle height.

    Just about every race inspired DH bike will have this issue if the seat is slammed too low, as most, if not all of them have an angled back seat tube. The Intense's, especially the new M6, Cove (Shocker) V10, etc...all have ultra slack seattubes. A good rule when building any race bike is to remove the spring & cycle the shock all the way down to find the bottom out limit, then set / mark your post for max insertion. And as mentioned already, this is especially the case on the small frames. I just finished my DHR last night & have plenty of seat post adjustment, but then again, mine is a large & I never slam my seat, even riding the shore ; )

    I buzzed the seat regularly on my size Large Orange 223, and that had 9" of rear travel. I ripped the plastic shroud clean off the seat on one occasion.

    Yeah the brake dragging, fall line skid rut, 2mph survival riding of the shore isn't really too conducive to high seats. I'll give you that.

    I'll also give you that I rode my bikes with non slammed seats on cypress and fromme and had a blast. Even on those goofy granite rollovers like the widowmaker 13 stairs etc. You don't need your seat slammed to ride that stuff. And the dhr seat towers are pretty low actually. What you think may be a lot of seatpost exposed isn't necessarily.


    If the tire hits the seat, move the seat as far foreward as you can. If the tire hits a straight seatpost, then the frame designer didn't do his homework.

    Slammin

    Since slammed seats are for decoration, use the smallest one possible. they are for sitting on in lift lines etc. At speed it is universally understood that if you are sitting you are slacking. Use an in-line headed straight up seat post and put that seat as far forward as possible. Any check of shorter riders bikes will show that the backs of the seats are regularly chopped into an arc either from the mechanic or the tire. going to a 2.35 will not save much seat foam from getting chopped, but it will make the bike lighter and easier to whip around for a smaller rider.

    You've got to be kidding me.


    After all this time of riding big bikes, you actually think that measurement is relevant?


    That's road bike sh1t.



    Go sit on one. There's no way in hell that measurement is a hindrance if the seat is slammed..........which you can do of course without the tire hitting.....

    I think it's only fair to point out that the small highline with 3" of seatpost exposed equals a small demo with the seat slammed. But the highline offers a greater range of seatpost height adjustment, and I have no idea how the different seat tube angles might effect things also.

    The real problem is if your butt is off the back at the same time you use all 7 or 8 inches of travel the tire is going to hit some delicate parts.

    We're talking about little people here, and we're tired of you tall people telling us what to do .

    Shortening the stroke on your shock is the only sure fix if you want to run your seat low.

    Fortunately, it is really simple and cheap.

    You need to put spacers under your bottom out bumper. I get mine from Home Depot or Lowes. They are just standard nylon washers. The ones I use are 1 1/8" OD x 1/2" I.D. x 1/8" thick. You can use as many as you need to get the stroke you want. You have to cut the notch out yourself, just make sure it is smaller then the shaft, so that it snaps on but doesn't come off without persuasion.

    Of course you'll have less travel. And since the DHR ramps up a LOT at the end of stroke, you'll lose some of your progressiveness but you should otherwise get the effect you're looking for.

    Here is some pic's (sorry, first pic is a little blurry, but you get the idea). I run this setup on my Rotec RL9. I'm 6'2, but run mine seat low. But even if I didn't, it would rub the seat tube with a 2.5 Maxxis, which are pretty small.

    Pretty much most (i.e. 8.5" +) long travel bikes have this problem. It isn't really a design error on Turner's part.

    Dave, feel free to chime in if you think this would be a problem on the DHR, but it has worked great on every bike I've done it on.

    house of mirrors

    The speshy and the knolly have seat post clamping things that are are way further forward relative to the BB than a DHR. That is why TT measurements on bikes like this are USELESS! Roady holdover sillyness, right Woo?

    Ricky, Great thinking but I would never suggest giving up travel to save a seat. You can get seats that are no more expensive than DH tires. If they are not 'big' seats will not hit the seat anyway, on a straight post with the seat reasonably centered on the rails. If one is a really short rider, then shoving it forward is only going to make the seats relationship more like that of a speschy or knolly without forcing riders with taller seat heights to have a seat position way forward. Ahhh the compromise.

    Woo. What is the actual measurement? I did a quick study of a slew of bikes at the first National this year in Fontana. The 'average' seat height was 24.5" from center of BB to top of leather roughly mid seat as using the seat post center line is for roadies. With all the changes in DH, an amazing amount of changes actually,since the Misser Brothers rode Turners, seat heights have remained close to the same. This is for riders from 5'4 to 6'1 per my notes. Yet the total range of seat height was about 2.5" with tall riders running seat heights that were lower proportionally to their height.

    Airwreck is right. Both a spec demo 7 and 8 medium are right around 17" from center of BB to top of seat tube. You can see the funky seat tube angles though. I've never buzzed a tire on the demo 7 but I have on my 8. I run the saddle on the 7 pretty far back too. The 8 is obviously foreward. These are with chainstays just a hair under 17". I don't imagine the axle paths being that different, since the main pivots between the specialized bikes and the turners are pretty close. On my 03 and 04 DHRs, I'd hit my saddle with the seat absolutely bottmed out in the seat tube but with how low the top of the frame was, I didn't like it that low anyway. But like I said, at 5'7" and probably riding a size too large, (technically I should probably be on smalls), I've never had a problem with either bike not being able to get the saddles low enough......even on the hallowed northshore™

    Both of these pics are with the saddles about where I use them for descending.

    I think Sverre may be willing to give up some of the travel to save the seat. If he is who I think he is. The Sverre I am thinking of, is a former (or still currently) owner of what has to be one of the pimpest Brooklyn Race Links on the planet. Seriously, the guy builds a wicked bike. And I say that being the former owner of one of the nicer Race Links around.

    Nice to see him rocking a DHR. I bet it's a nice one.

    You can't really compare the Demo line of bikes to many other DH bikes. The Demo line has really short top tubes and really long wheel base. This is because they have the seat mast moved quite a lot more forward than most any other DH bike out there. That's why they have a small Demo 8 with a 19.75" actual TT and a 46.25" wheel base (with only 17.0" chain stay). For comparison my personal medium El Cuervo has a 21.0" actual TT and a 46.0" wheel base (with 17.5" chain stays. The head angles are pretty close at 64/65 for Demo and 64.5 for Cuervo. You can see by this that a "small" Demo is really a "medium" or longer for most DH bikes with the seat mast moved way forward to give it a small TT and keep the tire from buzzing the seat.

    Hope this make sense.

    Yeah it makes sense if you're one of those wierdos that pays attention to top tube measurements.


    He asked if there was a 7 inch bike that didn't hit the seat when slammed. I answered in a blaze of fiery correctitude.

    Other than the longer than normal for a given size wheelbase, there's nothing odd about riding a demo. They're bikes just like the rest of them. They just scoot the seat tube foreward and give it a hefty angle to match the ride height of every other comparable frame. They copied that from some dirtjump bikes if anything. Innovators!!!










    Now somebody buy my medium demo 8 frame so I can get a small

    Thanks for all the replys guys.
    Dave, who´s mentioned we wanna save the seat? Both you and I know that when the tire hits the seat, it´s like hitting the rear brake pretty hard. If one is really unlucky this can make your rear skid out and make you crash. Worst case senario i know, but anyway..
    We´ve now tried alot of diffrent seat positions, and finally found one she likes. We moved the seat a bit forward, but not all the way forward, that looks plain ugly! This made it possible to lower the seat almost an inch. Excelente! She´s happy and can ride with more confidence. (The post is a Thomson inline, if anybody wondered).

    Ricky, thaks for your compliments on my RL It´s a great bike, and I´ve been riding it ALOT, but this year my curiosity for a modern geo racebike was too big. The geo and design of the RL is after all from ´02. Time flys eh? When picking a new race frame, I found the DHR to be the ultimate considering all aspects. It´s got nice geo, nicely engineerd, shock is easy to reach, grease guards, nice lines and reasonable weigth. Also the Norwegian sales man is awesome, and gives great cs.
    We just arrived in Whistler. Looking forward to a couple of weeks of dhr fun over here.

    Here is my 08. The seat height shown is my all around race height. I may drop it slightly for ultra steep courses, but no more than 3/4"-1" max. the post can go 1 1/2" deeper than shown before the tire hits.


    BTW, I really like this new bike I sold my Highline to get this & absolutely have NO regrets! She sits at 40lbs, 4 ozs as pictured. When my road cassette shows up, it will drop another couple oz's. I actually like the 08 large more than my 02 thru 05 mediums I raced on over the years, slacker, longer & obviously faster
