Cyclocross Frames, Wheels & Components / TanTan seatpost & 7x9 saddle rails
« on: September 09, 2025, 10:23:08 AM »
Are there 7x9 rail clamps/wedges sold anywhere for this kind of TanTan seatpost? The default one fits only thinner rails, and if any other bits came with it, I must have misplaced them...

What I meas is if with small chainring the chain is close to the lower chainstay in the front of rear triangle, just near the chainring.

Don't quite get how it could be too close there :D

Can I ask you if with chain on smallest cog and on 34t chainring, the chain touch orr i very close to the chainstay?

There's like 5mm gap between the chainstay and the chain (on the upper pulley), when B-tension is set correctly. If that's what you meant?

How does yours look?

Didn't really look if the radius matches. I have to check.

Still two months of winter & snow before I get to ride outside...

Size XS. Wheels from Leon.

7,9kg including pedals, bottle mounts & frame bag.

Paint job is not very high quality, chips easily from edges. Otherwise no big issues.

First time building, haven't ridden yet. I have no idea how much force it would take to really affect driving without hands.

I think I got it pretty ok after some twisting. Now has a small amount of spiral going into the down tube.

Why does the rear brake hose need to go around the steerer?

Drilling through would probably be a bad idea  ;D

Did the direct mount hanger make any difference compared to the normal one?

Maintenance, Mechanics, & Tools / Headset cable routing pushing steering to one side
« on: February 24, 2024, 10:00:09 AM »
Di2, so only brake hoses to route through the headset. Front brake hose exits the fork front of the steerer tube, so it doesn't really cause any steering force. Rear brake hose has to go around the steerer tube and some excess hose needs to be tucked into frame to allow full turning. There's limited space inside the frame for the excess hose, so the stiff hose always tends to push the handlebar to one side.

Any tips on how to avoid that?
