Any one own a Manitou HT?

[JeRkY]

At an ungodly hour this morning I won a Manitou frame on ebay... mainly for the pedals that were included (also has some cooks cranks which is nice)

However the frame has a typical headtube crack. Ive had a quick think and though up something that may get the frame on the road (or off it) again.

Obviously I could wait untill i recieve it to measure the thing up, but i'd like to get some quotes in prior to that.

What I need is:
The OD of the head tube both at the larger diameter and the machined away section.
The depth of the larger diameter sections of the head tube.
The wall thickness of the headtube.

also on a more fundemental note... is this likely to be a 1.5" headset, or the more usual 1 1/8th?

Lastly can any one provide me with the dimensional specs for the modern press in style headset bearings that have essentially a zero stack as they sit flush with the top of the headtube.. I was thinking that they would be more suitable for the top of the headset assembly.

To be honest I may just be able to get away with the external collar to hold the frame together, but the internal part should help spread the load.

Cheers in advance

For reference...this is what im trying to fix

looks like you got a cheap set of cranks there

Id personally polish it up and hang the frame on the wall...

Too many dents and cracks for me :roll:

But good luck finding the front mech if you do decide to build it up.

Does it require an odd sized front mech then?

yes, if you do a search on the forum there are some photos which show it's a band on one - but I don't know what size...

trying to find the thread.....

I reckon you should be able to have one 'made' to fit at the same time as having your parts made.
Don't forget to drill the end of that crack to prevent any further propagation

indeed, i was toying with the idea of actually putting a slot in the tube, removing the crack, and then having the collar large enough to cover it all, spreading the load and allowing the slot to act like it does on the seat tube to actually pull it in towards the internal componant.

TBH though your right, drilling it would be an easy and proven method to stop propogation.

Is the crack at the top or bottom of the headtube? It's just that if it's at the bottom, adding a cup and clamp will surely raise the front end interfere with the geometry a little (a la adding a suspension fork to a frame not designed to take one)

I'm sure I have just seen recently a new bike possible an Orange with clamped in headtube cups as you suggest doing. This would be a good idea and would do away withe potentially damaging process of forcing cups into place.

Good Luck !
