Rest don't care about and never measured,

Transition Covert (2012) in white because the black was sold out
Fox 36 Talas 150mm forks from 2006 as those are the ones I owned already
I bought it as I loved the one I test rode, I have no idea of the numbers

I reckon you really ought to be considering reach and chainstay length too

It's all about grip diameter these days.

Angles and BB height can be changed +/- 0.5 deg & 6mm

P.S. I like the "we're not geeky saddos on a forum" posturing from the novelty responders, you almost had me fooled... 😛

oh and bar/stem length and bar to ground height

tbh after riding the ukge series last year Id say mud clearance was the most important number!

Euro.You know the theory that somewhere out there is a perfect soulmate waiting to complete you?

Missus always says grip diameter is far more important than effective top tube length. 😀

Interesting. Never checked this before when getting a bike, my only criteria is 'does it feel right?'

frame: marin quake
Head Angle: 67
Seat Angle: 69.5
Wheelbase: 1145.6
BB Height: 345

seat angle seems lower than others listed so far. Sign of it's age? It was made before enduro become [i]the word[/i]?

Ok, question: Has anyone who'd fitted an angleset and slackened off their headangle by 1deg really actually noticed the difference without changing anything else?

Ok, question: Has anyone who'd fitted an angleset and slackened off their headangle by 1deg really actually noticed the difference without changing anything else?

I haven't tried it but I bet I would - I have this horrible curse of noticing tiny changes in set-up. It's very annoying! I've learnt that I have to check my tyre pressures before every ride because I'll notice if they're off by more than about 10%. I was going to say that I wish I was someone that could just ride whatever bike happily however it's set up, but it's that same ability to perceive small differences which makes me good at my dayjob.

Not to compare myself to F1 drivers but I've noticed that if you give Jensen Button a really good car he'll drive as fast or faster than anyone else but if he has a less than perfect set-up he'll drop way off the pace, whilst someone like Hamilton or Alonso can wrestle the most difficult car around a track fast. I'm more like a rubbish version of Button...

I changed mine by 2 and yep, pretty big difference. More noticable than adding 10mm of travel to the same bike.

Also changed the HA by 1 degree or so with shock eccentrics, I mostly noticed the seatstay bashing off the frame with that one 😉

Cotic Hemlock
165-ishmm coil Lyriks
65-ish head angle
no idea of BB height or wheelbase. Less and more than it used to be.

Yes, shortened the rear shock on the Remedy a few times, noticed difference each time, ended up with a 64 degree headangle with a 29er frontend (rockshox pike rct3) (26" frame and 27.5" rear wheel)
Have a 27.5" front end on way to try that as well, as was too much for 'just riding about' (not very 'involved') , but amazing on fast and steep stuff, in 29er spec.

Mine should be something like

Frame: El-Guapo
Fork: RS Sektor RL 150 Axle to Crown= 535
Head Angle: 67.5
Seat Angle: 72.5 - 73
Wheelbase: 1150
BB Height: 340 ~

Large Banshee Rune V2 running the neutral drop outs which should give me a head angle of 65.5 degrees or so with a 71 degree seat angle and a bottom bracket of 347mm.

It's running a 160mm BOS Deville fork with a 50mm stem and 780mm bars.

The wheelbase is 1180mm. All of the above assumes that the Devilles are 545mm axle to crown and that my Hans Dampf's don't have an impact.

BB Height: dunno (BB's off the ground)
Bars: 750mm (I cut them down from 780 so know this)

Wheels: MTB size

I am absolutely baffled as to why your average Joe would know any of this info, or need to know. Surely all the head angle/BB height/wheelbase changes the minute you sit on it, and depends on your weight, shock/fork pressures, etc?

FWIW, with a quick bit of googling:
Frame: Pronghorn PR6-LT
Fork: 2012 Fox Float 160 FIT RLC
Head Angle: 69° with a 150mm fork, I guess 67/68° with the 160mm one
Seat Angle: 73°
Wheelbase: 43.4"
BB Height: 13.9"

What exactly should I be aware of as a result of the above?

What exactly should I be aware of as a result of the above?

I would know that a 26" bike with a 69° HA & BB up in the clouds would ride like an absolute turd, for me.

But then I know what I like, in terms of the basics. HA, BB height, TT length, chainstays etc.

Heh.

TBF, it was a little bit sketchy with the 150mm DT Swiss rubbish, but the Fox really make it a different bike.

But then I know what I like, in terms of the basics. HA, BB height, TT length, chainstays etc.

Not knocking it, it's just something I never thought of.

Hence why I said "for me" 🙂

There's no right or wrong answer - you just learn what you like, but yes, if you break it, you probably are screwed!

Edit: I wouldn't necessarily buy without seeing it - but I would narrow my search down massively by discounting stuff it's unlikely I would like. That's not to say you do't hop on a mates bike every now & then give the a go.

Some things you can address seperately anyway, stuff like HA's can be adjusted with headsets, etc, but if it's in the right sort of ballpark I know I should be able to jump on something and it will work for me 🙂

Interesting feedback regarding the anglesets. Might be worth trying one into my zesty for this summers alps extravaganza? 😉

offset bushings?

As I mentioned above, some stuff you can change, with bushes, headsets etc.

My own bike is slightly short shocked to reduce the HA ever so slightly, done for more of a trial than anything, as I wanted to see if it made it even better (IMO it has).

SantaCruz Heckler 6.1 medium, 2011 Vengeance HLR 160mm, 555mm A2C forks. Offset bushings. Its probably all over the place!

BB height - 350mm
Chainstay length - 440mm
TopTube length - 570mm
Wheelbase - 1140mm
Bars - 745mm
Stem - 65mm

I do feel perched on top when the seats up, but good when its down. Would like something longer and possibly lower, but cant afford it 🙂

shortened the rear shock on the Remedy a few times.29er frontend (rockshox pike rct3) (26" frame and 27.5" rear wheel)

Strange Five
Fox 36 150 AtC 550
-2 degree headset cups
HA ~65
SA ~72
CSL 425mm
BB 315mm
effective TT ~600mm

The -2 degree cups are a recent thing and made a big difference. On certain trails (fast) it's fantastic but dulls the bike a bit when things mellow out. -1.5 cups are on their way!

Specialized Pitch but gone from 140 Pikes to 160 Lyrik so geometry is different. I had a play on a geometry webpage thingy and now know it all

scott that is slack!

chainstay length - forgot to measure... 😯

something tells me that the head angle should be slacker....i may have measured it wrong

gonzy

I thought my Heckler was short and stubby! Your BB height is very high, TT length very short and wheelbase very short too. Is it a small?

Obviously BB height is unsagged so the longer the suspension travel, the lower the sagged BB height will be in comparison (e.g. 120mm = 30mm lower, 160mm = 40mm lower).

Nicolai Helius AM with 160mm travel
160mm Marzocchi 55 RC3-Ti forks (545mm Axle to crown).

Head Angle - 65
Seattube Angle - 71
BB height - 360mm (Mahoosive 2.4" Rubber Queen Tyres = 340mm axle height))
Chainstay length - 430mm
TopTube length - 585mm
Wheelbase - 1120mm
Bars - 745mm
Stem - 45mm

It's a little short for me and the bottom bracket is higher than I would like with the Mahoosive tryes... very nearly perfect though.

out of interest, how many of the posters are quoting manufacturer's data sheets and how many are measuring?

And how are you measuring the angles? angle finder app' on your phone, proper angle finder/Inclinometer, plumbob/tape measure and some trigonometry?

Just out of interest like...

Is it a small?

i'm a shortarse so yes. the b/b height isn't helped by the massive 2.4" tyres.
it rides perfectly though.
might have to re-measure everything tonight

Angle finder on iphone or when in workshop we've got digital bevel box which is also used for setup on the machinery

Tape measure and Angle ap on phone - just make sure floor is level as a datum.

You know you want to

Ride it, if it feels good its right... I measured the ha only because people try and tell me it's too steep (turns out it's not) and pop it on the scales after a change to see how it's going. You can spend weeks with the numbers but until you ride it it's all just a bit of paper.

I used manufactures specs then calculations with trig to account for changes.

I measured mine with tape measure and a "calibrated to my worktop" phone app 🙂

people will thing it rides amazeballs

oh...but it does anyway!! 😀

my measuring technique is very old skool and low tech....consisting of a tape measure, spirit level set square and protractor....so probably not really all that accurate especially when done hastily.

right so i checked the geometry again and this time took my time to readthe measurements properly...
frame - Da Bomb Da Pukka 140mm

head angle - 62.5
seat angle - 64
b/b height - 365mm
wheelbase - 1110mm
top tube length - 520mm
chainstay length - 425mm

Iook manufacturer's measurements and then used [url= http://bikegeo.muha.cc ]the bike geometry calculator[/url] to see how the bigger forks affected the geometry reach wheelbase etc

head angle - 62.5

WOW are you sure? that's more than nearly all DH bikes.

Gonzy use the bike calculator above to see what it cones out as.
its really good.

Original angles:
http://www.hotlines-uk.com/SizeCharts.aspx?SizeChartID=109&ModelID=31627

I just downloaded the specs for my bike, plugged it into the calculator and got the full new set of numbers. It still rides bloody well 🙂

I rode my bike last night and fell off, It still rides bloody well 🙂 but ride is crap 😳

scottfitz - cheers for the original angles info for the frame.
i re-measured again last night and the angles are correct as i had posted them. i did make a balls up of the chainstay length as i had measured from the pivot to the dropoout instead of b/b to drop out so it actually measures 440mm.
but what i couldnt work out is how the hell they managed to get 584mm for the top tube. i pulled the tape measure out to this length and placed it along the toptube and the end went way past the rear of the seattube...me thinks they have got this wrong and my measurement of 520mm is correct.
i used the bike geometry calculator and the result were very similar to what i had got so i'm pleased to confirm that the bike is as big a slacker as its rider!!

I'm amazed you lot actually know this stuff 😯

I sit on it, it feels like a bike, I ride it

Can't believe anyone looks at all this stuff in any great detail

gonzy, the toptube length I measure is the effective TT length, ie the line parallel with the ground from centre of headtube to centre of seatpost. This will be longer than the actual tt length

i also did this and even with the tape measure starting from the front of the head tube, 584mm ended up somewhere over the back wheel way past the rear of the seat post!! 😕
