Giant MCM from 1997 - 7.57kgs

[GTsteve]

been lurking in here a while, but thought I'd post a pic/spec of my bike, to see what you think??

It's based around a 1997 Giant MCM carbon (20") and looks a little something like this:



I wanted to get it built first, then I can tune it further, as funds allow.

It was mostly built from parts I had lurking around, hence the hotch-potch look of the bike, but like I say I'm going to be reducing the weight more as time goes by.

There were many goals I wanted to achieve, in building this:

a) sub 8kg
b) Singlespeed
c) sub £500

Hi Steve

Just curious, given weight was a goal. Why do we get a hit us with a figure!

[GTsteve]

Sorry, my bad, it was copy-and-pasted from another forum...

anywhoo, here's the weigh-in

[GTsteve]

so a few additional bits turned up recently, so I got out there and got them fitted...

kcnc stem - minus 17g
Conti Twister tyres - minus 150g for the pair
Foss tubes - minus 80g for the pair
Steinbach brake levers - minus 65g for the pair.

total weight saving of 312g, should allow me to run a 1x9/10 set up with no difference to the weight..

[GTsteve]

So today, after gathering a few cheap bits recently, it was time for some gears...

First on the agenda was a 9sp cnc'd cassette @ 158g



Next up was a roadie Dura-Ace RM, tuned by me to 180g


and to make it all spin, a nice gold Ti coated hollowpin chain

Then it was off with 200g of SS kit and DCD, and to make it function, a Suntour XCpro thumbie at 73g, capable of covering the entire cassette range.

[GTsteve]

A quick change of seatpost and saddle, to a shortened Ti affair with SLR XC leather-clad comfort, and it was all bolted together..

[GTsteve]

...and after two seperate weigh-in's.................



7.570kg or 16.69 lbs

I saw a identical Frame on Ebay, not long ago, you've done well with the weight ( for an oldie), I like the colour also.
I love the transformation builds, more than the buy everything, slap it together builds.
Oh and welcome!!!

[GTsteve]

Cheers for the welcome, and the comments..

I've really enjoyed the hunt for parts so far, always hanging on for a good mix of weight and £££

I could go 50g lighter on the cassette, for instance, but it would be 3 times the price of this one, and I'm still (JUST) under the £500 price limit..

Hello MaxTurbo,
thanks for the post over at BikeForums!

I am super psyched to see you've already embarked on the same path as I'd like to with my Cadex. One of the main reasons I was searching for the specs of the bike, was so that it could potentially simplify the upgrading process. I love the work you've done to yours so far. Looks great! So, have you run into many issues whilst cutting the weight? Is there anything I should pay attention to?

Thanks again.

[RAgaTheMac]

Sorry, I meant to mention GTsteve on his bike. It was his conversion MaxTurbo put me onto.

I love the work you've done so far GTsteve. Its what i'm aiming to do as well

that 7700 Dura ace RD is able to handle the large rear cassette cogs?
