Just read this summary to a review of 5 bikes this mag considered to be near to perfection for there intended purpose,however I think the summary is very good and speaks not only sense but for all of us especially the last 2 lines 8),

How true.
-
which mag was that in? I'd be interested to see what they reviewed because I'm looking for just such a holy grail bike. I keep bidding on razorbacks on ebay and losing!
I think I will be forced to decommission my singlespeed razorback and turn it into my main ride bike and then use one of the proflex frames for singlespeed...

Its What MTB and they where reviewing (not testing against each other) 5 bikes they had rated 10 out of 10, both on performance and value
they are
Scott Genius MC10 :P
Yeti 575 :P
Giant Reign :P
Orange Patriot 66 :P
Whyte 46 :P
this is the first time I've bought this mag,have to say
its very good,no one sided blinkered views,just honest opinions given from more than one side of any discussion.
Simon
P.s Reading the reviews I think maybe the Scott Genius MC10 would be best suited for me,though I still have a soft spot for the Whyte 46,BUT THERE
IS ALSO and artical in there following Jon Whyte designing the new E-5,very interesting and I want one :P :P.

Isn't the article relieving themselves of any disagreements anyone would have with their decision. That paragraph is only serving the purpose of placing there view in the middle of any argument anyone might have. Kind of like a liability agreement.
I find all to be true in this paragraph. As for the definite listing of which bikes are actually perfect is destroying every idea it introduces in the paragraph.
If the perfect bike depends solely on the rider, why list any bike at all. The magazine is doing nothing differently in my opinion. They are still play the role of public rep for the bicycle industry.

You would need to read the 5 related articals first because then you would have enough info in which to still agree/disagree with there findings irrespective of the summary,
I just found the summary to be well thought out but it wouldn't put me off disagreeing if I felt strongly enough regarding one or more of the reviews.

Simon,
Picture this. Pick up a 99 or 2000 Evo frame. Alum triangle and swingarm. Weld stylish stiffener gussets into the toptube, headtube and downtube. Do likewise at the downtube, bottom bracket, and seatstay.
Add floating rear brake arm to triangle section and swingarm. Polish triangle, red anodize the swingarm and brake arm.
Assemble with fox DHX 8.5 i2i x 2.5 stroke, and Maverick DUC 32 with 6 inches of travel. Carbon seatpost, bars, and crankset. Stan's olympic wheelset in black with Hope brakes and stan's alum rotor.
Dang that would be perty!

Hi Simon,
mag reviews are ver useful as a guide but that is all they are - personal views of te journalists concerned.
Remember that What Mountainbike magazine is a sister magazine to MBUKand share many of the same editorial and testing staff. I would never consider MBUK to be the most qualified when it comes to objective reviews.
It just goes to show how true their words are at the end of the summary.

Damn that sounds sweeet,
we have similar idea's,
though I'd try and design in my own VPP system,
looked into a couple of designs but nothing I'm happy
with yet,
Hope floating rotors for me though [smiley=laughing.gif] and red caliper inserts,Goodridge or Hope braided brake lines,
Red Hope headset and seat pin clamp,
don't know much about stan's wheelsets,
so maybe custom built wheelset, Hope hubs, DT swiss
spokes,unsure about rims,wanna get away from Mavic
(personal thing,their French),Oh I seem to like Hope
stuff :-[
Carbon parts, your spot on,
what about X.O mech and shifters ???

Hi Simon,
Sprucey
PS - "MY" OZ is the best Oz in the world - not yours or anyone esle's on this site!!!! ;-)
Thats because I did your sealed bearing conversion [smiley=laughing.gif]
and I haven't got an Oz anymore :( but I'm sure my
son will let me ride it once in a while 8)
Simon.

Hi Mate,
on a serious note the Oz is a great bike and does ride beautifully.
I am dialling in the Razorback to ride the way I like but it's still not there for "sharpness" in both climbing and single track descending.
I can't put my finger on it but it is down to the extra travel from your sealed bearing conversion, longer stroke shock and the pedal platform damping from the 5th Element.
The Oz is about to get stripped right down. The BB shell is now very loose and wobbly so I am going to take it to one of my hi--tech boat building friends to get it bonded back in.
I'll keep you posted.

My bike is like beer:
The cold one in my hand is the best in the world!
[smiley=beer.gif]
And the fact that I got it for free... well it just "tastes" that much better!
[smiley=beer.gif] [smiley=beer.gif]
Now if I could just stop pouring money into it... :-[

wanna get away from Mavic
(personal thing,their French)[smiley=beer.gif]
Darn it. Why did you have to remind me of that? I was blissfully enjoying my "Frog wheels" (Ksyriums on my road bike) until you said that. Now I'll be ashamed on every ride. Luckily, my Proflex has Bontrager wheels with DT Swiss or Hugi hubs (I can't remember which). Those aren't made in France are they?
Yet another reason to ride my MTB more than my road bike... 8)
PS
Speaking of my Bontragers, as part of tightening up my rickety rear on the Proflex, I just realized that my rear hub was very loose. Still smooth, luckily, but I can't believe it was that loose without me noticing. Now it's tight, and that, combined with a new layer of teflon tape on my shock bolts, makes my bike feel new again. No clunks, clicks, wobbles, or creaks. Now the only thing that's "loose" on the back end is the flexy carbon swingarm. Can't do much about that one. I laughed out loud recently when I read a review of the Cannondale Prophet that said it had a flexy back end. Compared to what I' m used to (my two 5000's), the Prophet was so much stiffer (laterally) that I thought something might be wrong with it! (Now I kind of wish my swingarm was tighter like that. Simon, does your sealed bearing conversion make it stiffer?
-
Yes, Yes!
XO mech, and rocket halfpipes. Mutano raptor 2.4 front, Kenda Nevegal rear tires. Bontrager racelite tubes. Shadow stealth or carbon weave saddle, King hubs, with titanium bolt on skewer.
Helium pump kit for tires, shock and forks would round it out. (Yes, I am contemplating it).

At the risk of being contentious, I like the French and I want to buy a place there and retire - although that may be a few years away yet!

Why? It won't make any difference in weight. Sure, the molecular weight of helium is small, but so are the molecules, and when compressed, more of them fit in the same space - thus no weight advantage. (I've heard much more professional sounding explanations on this from chemists detailing the whole reason, but I don't remember all of that!)
Does helium have compression properties I don't know about that differ from regular air? What difference would that make?
Just curious...
-
Matno,
Personally I feel it does a little, unsure how other feel about it,the AL s/arm also
stiffened things up abit,I feel the rest of the flex is in
the frame at the pivot point,your 5000 won't have that problem,
Terry I'd have to have those X-O Trigger shifters,woooh have you seen the price :'(
Sprucey have I opened a can of worms there :P
anyway think you know my opinion on the French
so I'll leave this debate [smiley=laughing.gif]
Simon.

I am obsessed with big tires. And I got lots of helium to play with. Not much to lose except maybe a half pound.
I would love to visit France someday, also Great Britain, and Switzerland. Spain and Italy come next. Anyway did you know that a lot of Hollywood celebrities ( including my stuntman brother-in-law) are buying places in France? Does France make any Mountain bikes?

Summary article - I agree with Ionit on the "summary" - it's a disclaimer. Speaking of which - this is just my opinion. [smiley=laughing.gif]
Mavic - i'm not impressed with their rims anymore after owning 4 of them. Poor machine work. Always wanted them, got them.... gotta get something else next time. Maybe Alex or Sun/Ringle (why does everyone NEED to mention the Ringle part of that? It's not like they make what they used to anymore)
Bike - I like the World Class rear ends. Couple that with a 4-5" fork with a platform, a shock with a platform, some lightweight parts, a few custom pieces for added bling factor over the competition and .... oh wait, that's MY bike. ::) [smiley=laughing.gif]
Disclaimer - all of this is just my opinion and should not necessarily be viewed as fact. Batteries not included, some assembly may be required, some cars not for use with some sets, skill level 2, does not come exactly as shown, buyer pays actual shipping costs. ... and a partrage in a pear tree. :D
Yeah, i'm off my rocker tonight! [smiley=nod.gif] [smiley=redface.gif]

Actually, you might be right. I've heard that Helium leaks through tubes faster (once again, the smaller atom size), so you might REALLy be losing something...
If you're truly obsessed with big tires, check out this baby from Interbike:
It's the Surly Pugsly. Once again, a full rigid singlespeed (what is it with those guys?!), but this one seems to have built in suspension. Supposedly, you can run these 4" monster tires as low as 5psi!!!

I LOVE those tires!
Yep the helium molecules are smaller. But there are more of them. Right? [smiley=laughing.gif]

Wowie kazowie...
What a random thread! Helium, Single Speeders, Molecular Weight, and France. [smiley=groucho.gif]???????
Can't resist donating my two cents... (Is that tuppence Simon?)
Helium will leak out of your tubes/ust in a New York minute. My company uses it to leak test hermetic systems instead of other gases because the molecules are something like two orders of magnitude smaller than air.
In any case... at the same PVT, helium will be way lighter than air. (That's why blimps fly.)
France... hmmmm... better keep quiet on that one.

Thats close enough in my book Will [smiley=laughing.gif]
Yep thread has gone a bit off topic but thats fine by me,we're all friends here,its like having a cosy chat in the Pub [smiley=beer.gif]

here's my 4cents:
helium will leak out immediately. I own a remote controlled blimp and even with the mylar bag, an appreciable amount of helium leaks out in a day. can't imagine that rubber would hold the helium at all!
France and Hollywood celebrities - good, maybe they will all move to France and South Hampton (LI,USA not UK), Aspen, Vail, North Dakota, Montana and places like that will go back to everyday folk who actually contribute to society in some meaningful way. whenever I see that so called "celebrities" have moved in to a place, I know that that place is on its way to ruin. btw, doesn't celebrity mean fame? so how can one be "a" celebrity? weird, huh?
single speeders - cool, but really, what's the point? I can see wanting to uncomplicate things, but most single speeders I have seen have disc brakes and at least front suspension, kinda ruins the whole simple thing, doesn't it?
molecular weight - helium is waaay lighter than air (see my point about blimp above) but are tiny molecules, so tiny they will absolutely pour through your rubber tubes and you will be riding with nothing in your tires. suggestion: what about nitrogen? they use it in race car tires because it expands very little with temp. so tire pressures remain constant.
back to concocting my anodizing plan.

singlespeeders...
well i like the perverted-ness of it. a singlespeed bike with full suspension and formula disk brakes and carbon this n that.
singlespeed bikes ride so well and just feel uncomplicated. I love my singlespeed although it is a bit of a killer on the hills in scotland. Been riding my geared bike a little more lately.

Dennis,
Help me out here. From what I remember, Helium molecules are small, and possess a high degree of molecular distraction in the gaseous form. Air, which is comprised mainly of nitrogen, is heavier because of the degree of molecular distraction is low, packing them more densely in mass.
Contrary, water in the liquid form has a high degree of molecular attraction. To illustrate, an ice cube(solid) formed square, suspended in a weightless environment, will form a sphere upon turning liquid. The molecular attraction of the H2O molecules cling tightly to each other.
The jist of my question inquiry is, because of the low density of helium, will the gas compress more than nitrogen?
Yes, I tried to build a perpetual motion machine when I was kid. Batteries, motor, and generator, in a vacuum.

I like mine too (857) but having a time chewing up the jockey wheel on the singulator. had a regular derailler down there once..worked perfect...but not cool looking enough for vain me! [smiley=beer.gif]

Thanks for the thread Simon 8)
I have four bikes, two get ridden often. the other two, sparingly. Depends on my mood. Thank god for variety.
The best bike is the one I am riding at the moment.

since this is a VERY broad spectrum thread i'm going to go back and tell simon that i just bought the new xo shifters and they are freakin' fantastic! i broke the left pod lever on my x9's with my knee (at the same time as i shattered my helmet) and figured: hey, why not upgrade? these things shift so well i can't wipe the smile off my face (although it might be the concussion). i'm sure my credit card bill will take care of that, though.

So we can have perfection [smiley=laughing.gif]
glad you like them and your okay after your crash ;)
just reading through some of the replys I noticed the disclaimer word mentoned a few times and have to agree that could be seen to be the case,
however (though its creeping in) most mags don't usually worry about disclaimers over here and just say it as they see it,eg if its rubbish then thats what they'll say they don't usually sit on the fence or as we say mince there words,sueing is still a fairly new concept over here to the average mere mortal :P.
