Hi everyone!

I´ve got an old Mtb classic which has been given a slight modern touch :mrgreen:
It has been a labour of love for me, taking about two years getting it right.
I´m not really finished with it but this is as far as I´ve gotten til now.

My thought was having a nicely specced bike using more or less period parts with a racey touch.
As I get the inclination I´ll try finding lighter parts for it.
Thanks for watching

Hi bontyboy.
Good Work, to keep the Classic MTB's running.
If You will stick to 1997 parts, it will be hard to reduce weight.
If You need inspiration, take a look at My two Ducati posts, in this forum.
Looking forward to seeing Your upgrades.

Thanks Spoon,

It took two years and a couple of builds getting here, so not too many upgrades in the pipeline.
I´ve got a special Bontrager crown that I´ll build up in the future because the Marz is only 20 grams lighter than the frame...
I´ll check out your thread.

As I like pictures I thought I might as well put out some of the stuff that´s on the bike.
These wheels were hard to come by as most have ended up in the US and not many wanted to ship abroad.
So it took me a year or so to get them. They don´t come up very often so I was lucky I guess :mrgreen:

These are first generation Bontrager Race Lites with Chris King hubs.
These hubs were specially made for Bontrager and these wheels.
They have ceramic Bontrager Valiant rims.

Front wheel: 628 g
Rear wheel: 848 g

These also took a while finding.
My absolute favorite clip less pedal, Time Atac.

These are probably the lightest of this generation Atac´s as it´s Carbon AND Ti :beerchug:
They weigh 366 g.

Hope I´m not boring you?

Are these the ones that required time soles as the cleat drillings were different to everything else?
Up until recently I've run atacs since the time they used a standard cleat fitment.

Still reckon they're one of the best pedals out there, even if there's £200 and 20g difference between the standard atac and the carbon ti's....

jekyll man:

They use standard cleats. I´m not sure of the vintage but I think they are `97-ish.
Is there someone with catalogs that can determine different years?

I have a couple of the normal composite ones and the difference is about 40 g, so not a lot.
But it is nice knowing I can´t get lighter ones :twisted:

That is the story about this bike, trying to find nice, period components that are as light as I can find them, but still durable.
Much like Bontragers motto in keeping things light, but still passing the torture mill :thumbup:

I have to show one of my favorite parts of the bike.

The seat post :)

It´s a XTR M900 CroMo post that is pretty light considering it´s steel.
I´ve taken pics of my reserve post, which is in VGC+, while the one on the bike is more used ;)

Here is a picture showing the wall thickness, and how thin it is.

Image

It´s also pretty cool that Shimano went so far as to drill through the screw in search of lightening as much as they could.

Image

So my dream post would be a M910 made of alu. They seem to be pretty damn light, if I don´t go the carbon road...

Weight?
This post, 265 g.

Image

The one that´s on the Bonty is 262 g.

Thanks for watching.

This is one fine seatpost ! True metal-art ! -And the finish, -wow.
You mention carbon-way ? from 1997 ? I would choose the rare XTR. (old glued carb seatpost can be tired, after years of maturing the resins and glue(alu-clamp head).
It is also Your favorite, -right ?

Yeah, it is.
The black is glossy and the XTR logo is a silvery chrome.
Almost impossible to get right in a photograph.

Thanks for liking it :D

This will be the last update in a while.

A project that I´m planning doing in the future is making a nice and light fork.
The Marz is nice but heavy as you know what! 1760 g!!!

I got the chance in getting a very cool Bontrager specific crown with the steerer made of titanium.
Supposedly it is one of seventeen or so prototypes made.

Image

What I´m going to do is find a clean example of a Sid 80 mm fork, the older type, with legs that are 28 mm in diameter.
Then I dremel the crown off and use the legs that are left and presto! A smooth, light fork with a 1" steerer :D
That would be somethin´...
