this is not so much a cry for help as much as it is a cry of anger!

i'm currently struggling to put together my SS 69er (pieced together from bits left over from other bikes).

the two issues i'm having are:

1. the font disc doesn't fit properly!

it's a carbon on-one fork with a hope mono mini brake and the issue is that with a 160mm rotor the rotor barely enters the caliper and with a 180mm rotor it sits too far in and rubs.

should there be a spacer/adapter of some sort?

at the minute it's just 'as is' and i can't think how it's supposed to work (assuming that it is supposed to work without something i'm lacking).

2. the rear disc won't fit properly!

is there a magic way to set-up a horizontal drop-out set-up with discs???

should it work by me just making the chain the 'right' length for the chainring/sprocket combo (and then tensioning) and then adjusting the caliper position until it sits right with the rotor?

any help/sympathy appreciated.

also.....

i'll be running a steerer tube which is a little too short (it sits 5mm below the upper stem bolt).

i know this is dangerous (according to H&S.....and physics) but HOW dangerous do you think it will be???

1. deadly!
2. risky.
3. not-advisable.
4. should be ok but you never know.
5. quit being a sissy and ride the thing!

# 1. Does the caliper definitely meet ALL 3 criteria of- Front, IS, 160mm? 2 out of 3 won't 'do'.

#2. Yup. If it doesn't work u may need to try an alternative gearing to ensure the axle is within range of the caliper slots

#3. 3.

:)

Re disc, my 180mm disc rubbed and I just added a washer as a spacer.
Re stem, not advisable/risky.

anthony,

cheers, will double check all of those things and get back to you.

ray,

thanks, will see if that helps.

all,

the stem situation is one i'm only considering at this point (as i've got some steel forks which i can use instead) but i just wondered if anyone else has ever run one as low without a problem.

ok folks, here's where we're at.....

(as i know you can't sleep for worry about this!)

bizarrely it seems that it is/was a rear caliper which the previous owner had set-up as a front (short hose, right-hand lever etc...) and so now i'm using another brake.

and.....i've ordered a cheap Crank Brothers headset which has a 21mm stack height (almost 1cm lower profile than the Hope which is on there now) which should solve the steerer height issue.

and.....here she is:

I'll sleep better once you've sorted that saddle out

Seriously - that looks very tidy, as they say here in Wales.

Let us know how it rides once you've got the headset sorted.

yeah, the reason for that is that it's an old seat-post which had a snapped bolt and so, last night, i replaced it with a random nut and bolt.

now it's a real pain to alter - i spent the better part of 20 minutes fiddling with it before i realised the whacky angle and now am putting off changing it (it can now wait until the headset arrives from the uk).

will certainly let you know how it goes.....

p.s. Ian, wasn't it you i got those LX cranks from....?

Looks good.

And i'll sleep better knowing your sorting out your headset, don't want seriously injured/dead Gairy's do we.

The bike is looking good though :) .

PS. I never knew front/back brakes were different, in what way?

Front and rear brakes have a different spacing between the flange that sits flush with the dropout, and the disc flange.that's why the pugsley needs 2 rear brakes, as it is 135 OLD both ends. Simples.... :D

ray,

thanks - you're right, dead gairys are not a good thing!

gari,

thanks for the explanation - i never knew that.

nice bike. i think it used to be mine. :D

looks like my scandal that replaced it than it did when it was red!!

cool, it's doing the rounds.

i'm bringing it back to blighty to sell in October (as 4 bikes is taking the piss according to the mrs) if anyone on here fancies being the next proud owner of it....?
