Especially for light weight issues concerning cyclocross / touring bikes & parts.

A frame that can fit a 1.75" tire is a road bike? Even a 29mm slick tire doesn't fit on a road bike but... Whatever..... go ride both of them and learn something

I have ridden both and a lot of other bikes built up a bunch of different ways. I used to use my cross bike as a road bike just like you.

If you put slick tires on a mtn bike frame and fit a 53/39 crankset on it is it still a mtn bike? Sorta, kinda but you can't mtn. bike on it.

You can't do cross on your cross bike they way it's built. It's not a cross bike.

How do you know how and where I use my bike, are you following me every morning ride? Just for info I change a set of wheels in 30 seconds and do a very dirty cross with this bike. Sorry for your ignorance but this is a 50/34 crank. Someone told you that a cross bike is supposed to have one chainring and a 32c tire and you are blindly limited to that, wake up and stop cycling supermarket bikes and do some research before wasting my time.

That sweet black and gold bike from a couple pages back REALLY needs the deda gold tape to complete the build and some different bottle cages. The gold bits look pretty slick on that bike, but the yellow is a no go! Nice ride!

Do you think gold tape will be nice? I thought of it in the beginning but was a bit reluctant. I m also not very happy with the yellow specially because it gets dirty very easily. I recently found a black tape perforated in yellow background. Very nice looking, discrete and doesn't show dirt. But will think over on the golden Deda. The bottle cages will be full black carbon soon as I am not happy with the ones you see in the picture. They are light but hold the bottles too tight making the in and out a pain while riding.

Maxxis Flyweight 330 26" 1.95 bb drop is not much but noticeable compared to the Cerf's 28C. Just as reference you can see in the picture a 26" X 1.75 Conti Travelcontact and the Cerf's both in the same position but due to a bit different angle taken (see handlebar) the chain line looks same height in the 26" but you can see the outer diameter is significantly smaller. I don't have the 1.95 anymore but should be a bit closer to the Cerf's

bbdrop 50 and 2.4" clearence and i´d hit it.

my girlfriend has rawland drakkar which has bbdrop 56, mearured 27cm´ish bb height 50/559 furious freds, 165mm cranks. she does only commute on that bike.

if going to roots trail on that thing you have to have ambulance following you. commute. under 270mm with 172.5 cranks you have to be still careful.
50mm tyres gives you silkysmooth ride, not much slower than 23mm 700. ok, those cerf´s are much faster

My crank is 170 but I agree 270mm is too low for trail but not an issue for commute.

Interestingly I am in the process of round two with Chinese open mold frames from Xiamen iPlay and finished the wife's IP-105-D in size 54 over the weekend. Bike came in at 7.6 kg (16.85 lbs) - frame was 1110 grams


Have you got any pics? I'm about to bite the bullet on one of these having ridden a 56.

Want to make it as light as possible

Not to hijack this thread, but can someone recommend a decent alloy framed cross bike with discs? Specialized Crux E5 looks nice with hydraulic apex, but $2500 seems a bit much for an aluminum Specialized.

Why not build a chinese carbon one for 1000$ less?

FR-602 is one light and strong frame for $490 shipped. Irresistible. ..
