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
