Rear disc brake on 2001 Klein Attitude?

[Rocketman]

Since I bought a spare disc-ready wheelset, I thought maybe I'd give front
and rear disc brakes a try. My 2001 Klein Attitude has a 22mm (Hayes) mount
for a rear disc caliper (same as Trek). I was planning to get an A2Z 22mm
to 51mm adapter plate. Has anybody here tried the A2Z adapter on a Klein (or
Trek) hardtail? A Hayes 22mm hydraulic caliper with hose and lever is
$150+. Is there a cheaper/better option? What do you guys suggest?

Even if I do get the caliper issue sorted, the frame has no braze-ons for
hydraulic hose routing. So, that means using some klugey stick-on housing
guides that will muck-up the sleek looks of my Klein (which has internal
cable routing - a big selling point). I suppose routing the hoses under the
downtube and rear chainstay would be fairly stealthy; but it's still a
kluge. Arrgh. The European version of the Klein Attitude was available from
the factory with disc brakes. How did they route the hoses? (Photos would be
helpful if you know of any.)

I dunno. I'm thinking it's too much hassle and expense to go with rear
discs. I might just stick with a rear V-brake and front disc. It works
pretty good as-is, and keeps a lot of $$$ in my pocket.

Ideas?

Looks like the hoses are just routed internally as well. Why cant you do
this?

Although this guy has routed his outside.

Go with mech discs, like Avids, using your old inners and outers.

I have a Klein Adept Pro ( FS ) from 2001. I don't know how they differ but
I mounted a normal XTR caliper on the rear no problem. And I love it.
I agree about the cable routing. It has annoyed me several times. The
shifters have nice internal routing and my rear hydraulic brake hose goes on
the left side of the top tube through braze on guides that seem to fit well.
Ie my hydraulic hose seems to be the same diameter as a normal brake hose.
There are two brazeons on the front part of the toptube. Unfortunately the
hose is clamped down with zip ties which makes it even worse. Aaarrrggghhhh.
>From where the shifter cables come out there are no guides and the hose is
kinda zipped down to the rear shock and whatever they found on the way down
to the caliper.
It is not put together by the factory.

I wouldn't try to save $$$ by not getting a rear disc. I really appreciate
the nice modulation on both levers. However I am contemplating doing just
that on another bike I have. Not from being cheap but simply 'cause there is
no caliper mount on the rear stay. Maybe a hydraulic rim brake in the rear
and disc in front...........

I can't see much from this photo (rear discs are exactly opposite the
camera); but it looks like this Klein has I.S. disc mounts.

Yes, on a bike with I.S. (51mm) disc mounts.

Um, thanks Matt; but I don't think you got the crucial point. Obviously, if
I could go the easy route (I.S. discs front and rear), I would. That's not
possible. My 2001 Klein has the older Trek/Klein/Fisher/etc 22mm Hayes disc
mounts, which are inside the rear triangle, not outside of it as I.S. mounts
are.

You mean you're using XTR V-brakes on the rear? Or did you find a way to
mount the XTR rear hydraulic disc caliper?

Mmmmkay. So your Adept already has the cable guides brazed to your frame.
Is that right? Mine does not. It sounds like you do have an XTR hydraulic
disc caliper on the rear. How did you mount it to your 2001 Adept? Did you
use an A2Z 22mm to I.S. adapter plate? Did you use the Shimano 22mm to I.S.
adapter? Is there enough clearance?

Aaarrrggghhhh.

My Klein Attitude (2001) has no braze-on cable guides at all - only the
internal routing holes.

Yeah, that's kinda what I expected. It's uncharacteristic of Gary Klein to
be this sloppy.

Yeah, I have several bikes like that; but my titanium bike can have I.S.
mounts added for like $120 or so. It's cheaper than buying a new frame...

> Maybe a hydraulic rim brake in the rear and disc in front...........

That could work well, IMO.

Hydraulic disc caliper as you guessed.
I took a closer look and yes I do have an adapter in the rear. It seems to
be about 43 mm between the holes in the frame. The caliper itself is
fastened on the adapters 51 mm holes.

The clearance is OK but it seems that it is 43 mm to 51 mm adapter.
Evidently our frames differ just a bit here.
The adapter in general looks to be really sturdy and I wouild imagine it is
from Shimano.

Do you have three internally routed cables then?

Oh yes, my bad.

Maybe you could get an adapter (ala frames that have no disc mounts) but
that may mess up your nice lines :)
