Dyna-Tech MT4

[Mobes]

ive just noticed my cable routing is different to yours. mine is along the side of the tob tube. does this mean mine isnt an MT4 or just a different year?

i actually got a Dyna-Tech seatpost included in the sale so im going to use that for now.

i will pm Gil_m, thanks for the heads up

Yes, yours is a slightly later version... mine is a '92.

I also notice that you have a separate seat clamp... maybe this was changed to this on later versions due to slippy seatpost issues I mentioned earlier???

I have some chromed Tange 'big fork' if you are looking for some nice rigid forks, let me know if you need any pics etc...

These frames ride really well... nice and zingy without being too flexy.

Be careful with BB length.. the chainstays on the MT4 are quite thick [thicker than on the MT3 due to being Ti] and run very close to the end of the crank arm with a 50mm chainline. I have seen a few comments where other members have scraped the chainstay with the crankarm.

Cheers,

Chaser.

i started mocking it up last night and i fitted a 113mm ISIS bb so that i can use the race face cranks i have and there doesnt seem to be an issue at the moment but i will keep an eye on it

i will get the back out in daylight (if i can find some at either end of the working day) and take some photos of my mock up so far

Yes indeed..
A question for you also, -obviously the frame tubes are bonded into the lugs, but how are the titanium chainstays joined to the dropouts or (if they're Ti), the dropouts to the seatstays ?
-thank's.


Lovely frame by the way Mobes, good score! -Should be really nice, smooth ride.

I've just noticed the top pull front mech routing on yours.. it's bottom pull on mine -I thought I had a '93 model but seems to be earlier.. :?

The chainstay and steatstays are titanium, these were plasma-arc welded to the dropouts.

The seatstays have a bonded-in end cap.

The sub assembly was bonded into the ports in the bb shell, and the seatstays are then bolted and bonded to the lug underneath the seat clamp.

We progressed with plasma-arc welding sub assemblies, and deveolped our first full plasma welded frame the Torus.

The seatstays are definitely steel on mine! ?? :shock:
