Isaac Sonic - Limited Edition nr. 179
Moderators: MrCurrieinahurry, maxim809, Moderator Team
Nursing a bit of a pride injury, but I'll be ok . I was literally going 10kph and tried to double back a missed turn and hit all gravel and sand when my front wheel washed out. Cracked the top tube on top and bottom (but not on sides) about midway down the tube. I think it was the 3rd time I had ditched it, but the fist time anything cracked. I think had I been going faster it'd have been ok, oh well.
As for performance, I've owned a 2010 Merckx EMX-5 and a Canyon Ultimate Slx and I prefer the Sonic to both- I'd say it's a real 'classics' bike without the soft ride.
BB is darn stiff but not in the way that some of the new superstiff bikes (Canyon) don't carry your momentum when you pedal, the bike moves with you.
The ride is a bit rumbly, but never harsh, the good side of the EMX-5. It carries it's speed well on the flat, maybe a slight end to the EMX-5 here, but it's better than the Canyon.
Climbing, it's weight is more like the EMX-5 than the Canyon, but the rear wheel seems a bit closer under your butt so it moves when asked.
Descending is fantastic, it has high speed stability, stiffness, feedback, planted feel, and nippy when needed (EMX-5 falls down on nippiness I think and the Canyon is too flighty for me).
For what it's worth, I saw a 2012 Boson the other day and I'm pretty sure it's the exact same mold as the old Sonic, not sure about the carbon layup etc tho...

Geeking out for a sec, looking at the geo charts of the emx-5 and the Isaac, in fact what I'm feeling is right there in the numbers. I don't mind the long front-center of the Isaac.

this is nice! its one of my favorite isaac-designs! although wheelset goes perfect with the frame.
maybe other bottle cages.
not precious? hm, thomson-post, reynolds-wheelset, prologo saddle, the frameset.... those ar really nice parts, in my opinion.
only picture could be better.
good ride! and successfull racing-season!

Only have my iPhone for camera but those were taken at dusk, maybe a bit better...
The post was off the Sonic I broke, zipps here from Privateer before he jumped back to oz (thanks mate, they rock!), found frame very lightly used for 400 Eur. Cages are kinda weak but they match the frame and work ok.
All in all, 1000 Eur before wheels taken into consideration. Doubt u can find a 1000 Eur bike as good as that anywhere

@simon:
yes, frame became 74 gramm lighter (now 848 gramm), the (3t!)-fork 14 gramm (now 298 gramm, with expander).
best regards
