Let's talk disc brake road bikes
« on: April 14, 2015, 06:06:44 PM »
I'm thinking about adding a road bike to my stable and have a few criteria in mind, so I'm just starting to gather data and look at options.

1. Pretty sure I want to go with Disc brakes, why because I love them on my Mtn Bikes.
2. Want some that is an "Endurance/Sportive" bike
3. Can fit at least a 25mm tire, but would like to fit a 28mm if possible.
4. Will most likely go traditional cable controlled Ultegra groupo.

What I have found already.

I'm pretty sure I need to be on a 56cm frame, I tested a Cannondale Synapse, which had a relatively good fit, and a BMC Gran Fondo, which would need a lot of adjustment to fit, although I like the BMC bars.

So looking at geometry, nothing quite lines up to the Cannondale for dimensions, or at least that I can find.

Looking at a good blog, there are a couple choices, but not sure on them..

So what do people know or say about the options?

What do you think about thru axle type disc road bike frame ?

Here is one picture of our newest road disc frame for reference, it is a super light model 092 SL road frame, the other is V-brake version 082 Sl road frame.

BTW, we make these 2 models frames with BB86, no other options

I am happy you started this thread CMH, I am also looking for a dic road bike, but also flat bars.

Disc brakes may become mainstream quicker than thought:

Once a standard for thru axle stand from the crowd, I jump!

Peter,

The second Pic of the disc brake frame looks very interesting.  I'd be interested in more details about the geometry on this frame.

Peter,

Those numbers look the closest to the Cannondale Synapse that I've seen, except there is no 56cm listed, which is pretty much the size I would need.

Seems odd to me the chart goes from 52cm, 54cm, to 58cm, skipping 56cm.  I wonder, since it's a new frame design, if the 56cm tooling isn't ready yet.

I am also wondering why there is a big hole at the seat tube.  I admit I don't know much about road bikes, so maybe it's obvious to others but someone please explain the design.

From the pictures it looks like the post clamp might sit down inside a pocket and the hole is to access the clamp?

What size post does this frame use?  And is it standard round or a proprietary shape as many road bike posts are.

Peter,

Can we see the front fork brake cable clamp.  One complaint about the other China disc brake bikes has been the method of clamping/securing the front brake line.

Also, what is the front derailleur mounting on the 092 SL?

It's got disc brakes and a thru axle- shouldn't it also have a 1X drivetrain?  :)

Peter,
I'm interested by the 092 frame too.
What is the weight of the frame? And the fork?

If I build one it will be 11-spd but because it's road bike, most likely 2x11.
