Yeah, it's not bad is it

Hybrid SID!

Been playing around with the SID's today.

I've made a hybrid fork from an '03 SID Race and '07 SID World Cup; taking the carbon steerer and crown / leg assembly and 'mating' it :shock: with the 'race' lowers and Pure-delite damping rather than the Motion Control damping in the WC's.

Result is a 1200g fork, which isn't bad Total weight (with Conti Speed Kings) has now dropped from 18.6lb to 18.33lb

I've also fitted a Middleburn Duo instead of the RF Turbine triple chainset and then swapped the Dura-ace (12-27) cassette for an XTR M953 (12-34) one.

The Duo works much better with the Pauls/Dura-ace Thumbies as it was a bit awkward moving the amount of cable needed on the triple.

Nice one The silver lowers look better too.

You could save a bit more rotational weight with 2.2 mountin king's supersonic or 2.1 speed king supersonics. Schwable Racing Ralphs are another option.

What are you doing for tubes? Going 'Ghetto Tubeless' could save you a few more grams and you get no flats which is an added bonus!

A little up-date

Swapped out the orange s'post clamp and headset and fitted the original black Kona one and a Chris King. Also added a set of Salsa Rasta Ti skewers which go nicely with the green/gold/red of the Kona logos ....

The silver forks look much better as previous post But 18.33 pounds is obscene :shock: make mine look like a lump of lead :cry: How much do the forks weigh now :?: just wondered Thanks.

It is quite light and the tyres are 2.4's :shock: Could shave quite a bit more there, but I wanted big volume Could go tubeless as well on these rims

The forks are now 1200g

Most of the weights are on page 2. I am of course assuming my digi scales are reasonably accurate, which I think they are as I weighed kitchen weights to check

Cheers

That is light :shock: but my carbon mars cl are only 1190 grams with trimmed steerer and lockout knob removed and with plastic valve cover (the manitou one weighed 14 grams :shock I think that the other pound is in my wheels I will go tubeless on sunday as my rims are 819 tubeless,This will save me about 300 grams

I think that I like yours better though :cry:
