LightWeight Cyclocross Bike #6: Dave's K2 proto

Numero Seis is Dave's "Giant" cyclocross bike, Dave says, "its a prototype K2 frame that we (i used to work at K2) made for Jonny Sundt. never hit production. My team is sponsored by giant so thats why the Giant decals. :)" Pretty cool. BTW, whatever happened to Sundt?

This bike/frame probably has another full season or two in it & I think our team deal with Giant may be ending. So, next year will probably bring new paint & new decals for whatever bike manufacturer we get. These frames handle & ride like no other so I'll be on them until they break or wear out. :)

Lightweight Cyclocross Bike #1: Johns Morati

So, I think there are some bikes out there that deserve a little more
bandwidth because theyre pretty bad ass. And seeing as how I have this
thing with light cross bikes, Im going to start featuring cyclocross
bikes on this site that are under 18 lbs or 8.17kg. If you have a bike
thats under this limit, drop me an email at

Bike #1: John's Morati

A really sweet Euro-titanium rig with matching Morati fork. John
reports that he had a custom steel (read: high end Norcal framebuilder)
fork on there before and that the bike's ride quality improved
dramatically with the addition of the Morati ti fork.

Other totally bling so bright it hurts (bsbih) components are the no longer in production
Sweetwings cranks.

Lastly, John previously rode on carbon Zipp rims and Tune hubs but recently
ordered the Reynolds Stratus DV wheelset. Pretty nice. Build spec and
additional pics below.

Some might argue that the AX Lightness saddle and the EC90 bars would
be too weak for the rugged abuse a cross bike endures, but John being
at 140 lbs doesn't put too much stress on these components.

For more information about some of the components on this bike check out the following:
