On the Road with the Gravel

I finally finished my gravel bike. Here are a few pictures and the parts I used.

- Frame Tan Tan GR201 
- Elitewheels ENT Gravel
- Riro MTB Carbon Crank
- Rotor T47 Bottom Bracket    85.5 mm                             
- Wheeltop New GeX Gravel Bike                  
- SPEDAO 12S road cassettes
- KOCEVLO Dimension 143 carbon saddle                                       
- Sram x01 Eagle                               
- Zipp Service Course handlebar tape                       
- Schwalbe G-ONE Overland                     
- Shimano brake discs                       
- 40T chainring 
- Lexon Unox Gravel

No, everything was assembled correctly. I read that the chain and sprocket need to be broken in and that it will get better over time. I have installed and adjusted everything correctly so far.

In my YouTube video, I only pull the chain over the shift pulley, and even though I only pull over this one pulley, it is already very loud.

Hello,

I'm currently working on my gravel bike and have now installed and adjusted the Wheeltop EDS GEX. My setup
Simple combination without a front derailleur
RiRo carbon with 40-T chainring, Spedao 11–50 cassette and an SRAM X01 chain.
What's puzzling me a little now is the noise the chain makes as it runs over the derailleur pulleys, the cassette, and the sprockets. It's quite loud, and I don't know if that's normal. I can only describe it as a rattling noise.
The chain was cut to length correctly according to the instructions.
However, I think it's due to the Wheeltop derailleur pulleys. When I pull the chain through the pulleys without the derailleur mounted, it sounds almost as loud as when everything is fully assembled.

Has anyone else had this problem?


Here are two videos where you can hear the noise clearly. I aligned the derailleur hanger precisely using a tool. Everything fits perfectly.

Thanks for your help. I managed to fix it with the Lexon handlebar. It really was just the C-ring. I've now installed the plastic one and everything fits perfectly. I didn't have to recut the fork.

a) Use the plastic C ring
b) It looks like the steerer is not cut low enough so you cannot compress the headset with the handlebar.

Thank you, I will try it with the Kusntoff C ring. However, I think it was too high. OK, if necessary, I will have to cut off a little more. Thank you for your help.

Here is another picture from above.

Hello, I have a problem with the steering head bearing. It has too much play. Even though everything is secured, it can be moved back and forth with a lot of play. The Lexon Unox is installed. I hope I didn't do anything wrong during installation. Both bearings are in place and there is a metal ring on the upper bearing that looks like a "C."

My frame has arrived.

Hi.
How long did you wait for the frame to be painted and shipped from Tan Tan?
I placed my order with Jessi on September 29 and still haven't received any information that the frame has been painted.
I'm starting to get worried.

Hello,

you have to be patient. I placed my order with Vivian on September 15 and received the pictures of the frame and the tracking number on November 3. I guess it will take another two weeks.

The rated capacity of a powerbank refers to the rated voltage of 3.7V of a lithium cell of a powerbank. Means that a 3S battery with 11.1V rated power can store the same energy with ⅓ of the rated capacity.

10,000 mAh * 3,7 V ~ 37 Wh
3,333 mAh * 11.1 V ~ 37 Wh

Thanks for your explanation, I overlooked that. You're right, of course.

Why? Just buy one that fits into downtime storage and you have to find something to fix it inside the frame.

That's right. But it also has to be a power bank (with Power Delivery and 12v output). It should also have 20,000 mAh so that it lasts at least 10 hours in normal light.


@darario, Thanks, I'll take a look.

Edit: Okay, these 3S LiPo battery packs are clearly too weak. So it should be at least a 10,000 mAh or, better yet, a 20,000 mAh battery.

Should be no problem. The only thing you need is a handlebar that allows cable guiding under the bar like on the photo for the lamp cable.

I ordered the Lexon Unox. I'll measure it when my frame arrives. I don't see any problem with the cables, but I do with the power bank.

Hello,

has anyone tried integrating a lamp with a switch and power bank? It would be nice if the power bank could be placed in the frame like on the Rose Backroad.
The lamp is a Supernova Pro Mini with high beam.

Hello,

which bottom bracket would you recommend? I actually wanted to buy Shimano Hollowtech T47, but it's sold out everywhere here. Is there a good one on AliExpress?
Oh, and it should be 24 mm for a Riro crank.
