Old MTB suspension fork [OT]

I received this week my old MTB fropm Italy, and I was thinking to adapt to a street quite like style. The model is a Grandis (a small and local bicycle-making http://www.cicligrandis.it/mountain-bike-su-misura/storia-grandis_ENG.htm). The bike is still good, and the frame look more hybrid style then MTB. The problem is the fork. It completely lost the ability to rich the position.

I was wondering if someone knows how to fix it, or if it is better for me to move to a cyclocross fork (like this http://www.wiggle.co.uk/surly-long-haul-trucker-touring-forks/)

Looks like fun!

It completely lost the ability to rich the position.

No idea what you are asking here I'm afraid. Does it not move any more? Or does it not return after it is pressed down?

It does not return after it is pressed down (sorry I didn't know how to describe the problem)

I can't see what make / model the fork is (and don't know much about suspension forks), but it may well be serviceable. If so, this will probably be cheaper and more appropriate than fitting a fork designed for a cyclocross bike. Does it have a make / model on it somewhere?

No no model at all. I wrote a message to Grandis to ask info about it. Anyway I am thinking to use it only on the road, changing the tyres with Continental Ultra Gatorskin City MTB Tyre. So for this reasons I have in mind the option new forks. The service is around 60-70 pounds (as from the web). Quite a lot

A rigid fork like this might make sense then:

Right this is the model I was thinking to buy. I had, while we are writing here, a look for suspension servicing... and yes, the average is around £60! A lot... I ll try to go Saturday to a shop to ask for it and then decide.

I can't tell what those forks are. Early Marzocchi (sp) maybe even a Rond fork??

If you must have a suspension for just get something from ebay. Maybe a Rock shox Indy or Judy if you don't want to spend much. Servicing the forks you have might not be worth it. Like most things in life depends what £££ you want to spend.

As above, go rigid fork if it's going to used as a road bike.

ok... I need a 26 MTB rigid fork 1 inch with a distance axle-crown of 44-46 cm...

I m not able to find one!!! I was looking for a Kona project 2, but the 1 inch version is not available. Suggestions?

Suggestions?

Look harder. Any time I have been looking for Project 2 forks 1inch is all I can find.

You might need to change to a threaded headset/quill stem but that shouldn't be too much hassle.

Alternatively, if you can get a threaded fork with a long steerer, just use the aheadset you have.
