Retro mountain bikes

I'm not sure Magura's will fit. You can turn the mounts 180° (and switch the left and right caliper) but with the newer type rim brakes, the calipers are helt in place by the brake booster and you can't turn that one 180°.

Oh, you think mount heights are different?

Guess I’ll have to get some wheels in there, and measure stuff. I’ve worked out that the Hearse brakes fit the mounts ... £££

Anyone know what the mount>rim meadurement for BMX u brakes are? Those are insanely cheap compared.

Magura fit standard (canti) height and that's 250 mm (axle to center of mount boss). I've measured my "U brake only" Scott and it has mount height of 320 mm...

I have some working U brakes in the shed. Drop me a line of you need one (I'm afraid these only fit in the rear).

These were the brakes originally on the tandem frame @Skülly

AH!

Thanks Mat. All a but rushed yesterday.

Someone’s selling a nos set on fleabay. For £450!!

Oh I see, thanks. For some reason I thought Maguras fit above the rim, guess I must have seen some flipped in the way you describe.

Thanks for the offer of U brakes! As I have to repair the bike, I might just opt to put mounts in a new position

PS no wonder you don’t have them any more!

PPS Shouldn’t you be working?!

On a thrilling conference call! You could also use roller-cam brakes on the bosses, I think.

I'd have been tempted by this if I lived closer

Great stuff. I'm currently building an Mi80 from the same era.

Uuuh googling those now /no idea

.

Boom!

Excellent thanks @Mat-CR. Let’s hope 90mm mount spacing is all good for these. Found a pair.

Thanks to @Frerman , I now have this quite serviceable Marin Eldridge Grade.

The only obvious issue is the crankset being replaced with a black Suntour one.

How likely is it that I can find a silver Shimano Deore or XT triple?

I guess this would work?

What are you exactly looking for?

Silver Shimano square taper triple. The original groupset is Deore LX 8 speed.

gorgeous!

That groupset was black, no?

I have 2 silver cranksets. Both Sugino. One is Mighty 900, the other... should check, don't know it any more.

Edit: sorry, you need Shimano.

Ah, interesting point. Bits on the bike:

Shifters have black bodies with chrome brake levers
Mechs are also black with chrome bits
Front LX hub is black
Rear XT hub is silver
Brakes are silver
So yeah, cranks prolly were black.

No, cranks where probably silver White Industries cranks that came standard on these Marin bikes. Brakes are Marin Lite and as far as I remember front hub was White Industries too.
