Hello,
here my sonic ltd. i had an accident with this bike, which caused a crack in the chain stay. but i got it fixed. now i am using the bike for training and street-racing.
it has a 920-gramm-frame and a 370 gramm fork (without headset).
i built it with parts being there, like dura ace shifters, breaks and derailleurs, thomson stem and kcnc seatpost, fulcrum rs crankset and a powertap-wheelset.
an inconspicuous, but, in my opinion, valuable bike, which i use with pleasure.

and last picture from todays recreation- ride: season is ending, winter is coming end of the week, so i am going to change to my steel-vehicle soon.
it does not make sense to show the bike with another wheelset, because i am only riding it with the powertap-wheel.

Hello,
thanks for asking. concerning the weight: i only can guess: my 2007-sonic-build (i already showed it in this forum ca 2 years ago: sram red, tune/reynolds wheelset. tune speedneedle saddle) was 6,08 kg, with computer and pedals.
this one is much heavier:
the frame is 47 gramm heavier.
wheelset ca 800 gramm (powertap!)
saddle ca 50 gramm
additional weight of dura ace- shifters, -derailleurs, -brakes? 300 gramm?
all in all i guess it weighs 7,2-7,3 kg (16lbs). not a weenie, but although not to bad. particularly with regard to the uci-weight-limit of 6.8 kg. i have to consider this in some of the races i participate (senior 2-amateur).

after riding a 2009-sonic for 1,5 seasons, i was looking for a new frame with, more or less, classical appaerance. cannondale evo or stevens comet would have been nice, but their geometrys do not fit, parlee is to expensive (for racing! :D ).

so i rebuilt my 2007-sonic. 132 gramm lighter as the 2009, and, meanwhile, i really appreciate the classical, principia-like, look.

probably, i am going to get the paint removed and let it repaint in clear coat or matt-black.

at the moment, frame weight is 922 gramm, 3t fork 298 gramm (cut), + headset and screws, etc, makes a weight of 1320 (2.9 lbs) gramm for the complete frameset.

whole bike ca 6,8 kg (14.9 lbs)with the kinlin/tune wheelset.

Nice, very clean, fast looking bike, well done, seat post looks a bit angular for that frame to me, not that my opinion really matters though. Cheers.

thanks.

i love the Thomson-parts, especially the setback-post. :)
but if i am going to get the frame painted in matt-black, they won`t match anymore, so i might have to think about something else. or paint the thomson-parts in mattblack as well.

best regards,

why not use the original blue Isaac seatpost? it's pretty light, and can easily be tuned with a Ti bolt for the clamping.

Oh, I think you will kick yourself later for removing that blue hued gloss you have on that frame now. I would even go back to the original fork and look for weight savings elsewhere. The matte thing is kinda "yawn", so 2011... The blue is different and not often seen. My 2 cents...

I agree, keep the blue paint, it's totally unique.
I would rather like to see some more black parts, like front and rear der. And brakes.
Make the frame the crown juvel of you build (and black out all other parts) it's worth it .
And please remove the Big 3t logo on the fork.
I really like this bike, a lot.
I think you hit the geometry spot on, and i would love to see it with some high profile rims.
Please dont paint :D

hello everybody,

thanks a lot for your comments. :)

i know, matt-black is "en vogue" at the moment, but this is not important for me.
the idea for repainting it black (or nature-carbon) came from the black-eloxated principia ellipse, i have been riding for several years. i always loved this bike´s look.
the isaac`shape is very similar to the principia, tube-diameters are nearly the same, so i think, it would look great in black as well.

but i am still not shure about this, i am calling the painter on monday and then everything else.
your ideas about the frame make me seriously think about the repainting, thanks for that!

@rumsas: yes, the 3t-logo has to be removed, its absolutely annoying.
but beyond the weight-saving, i really like the geometry of the 3t fork. the fork rake of 46 mm fits perfectly to the 52-frame´s steerer angle of 72,5°.
i will add a picture with my fulcrum-rs-wheelst. i am curious about it as well.

@simon: my problem with the isaac-post: the rough adjustability: i dont get the saddle in the optimum-position! :(

thanks again for your suggestions, i will think about it. :beerchug:

+1 for keeping its original colour, it's simply gorgeous and unique. I can tell from first hand because I just bought one :mrgreen: I like black bikes as well, but a blue LTD would be just about the last to sacrifice for that purpose. Because I like original, I'm not a big fan of the extra Isaac logos on headtube and seattube either. :oops:

Hi,
principally, i don´t have a problem with changing original design (maybe i wouldnt change it on a colnago, but its okay with an isaac, in my opinion. :wink: )

but usually, i am rather the guy removing logos than adding those.

in this case, the white logos have been a try to create a counterpart to the white "3t"-logo of the fork ( the one on the seat-tube is already removed). better solution would be, to get rid of the 3t-logo, no question.

(the headtube? in my opinion, the weak part of the isaac-design, difficult area. :) )

if the frame should be repainted, only one logo will remain, but nearly invisible.
