You're so wrong, my friend!!!!
I need another bike!
In fact, several 

On a serious note... it's not quite that frequently.
Sometimes it would be twice a weekend, sometimes I might stay a whole month with the same tire.
I'm an old weekend warrior, anyway! 

My friend, you need another wheelset. I couldn't imagine changing tires that frequently based on terrain I want to ride. In fact, on my gravel bike, I keep a separate wheelset when I want to ride it on-road, but even with that I am so lazy I seldom feel like changing even the wheel. Thankfully my gravel tires are pretty smooth rolling on road so for most shorter rides I just leave it all alone.

Hello everybody.

I have a road bike that I intend to make smart-trainer only... it has some issues with the frame, but it can work very nice in the smart-trainer. The frame is carbon, disk-break, flat-mount, but for the new purpose, I just want to fit the cheapest decent rim-brake capable to shift 11 cogs (11-34), and some cheap 1x crankset that can resist nonetheless to the job.

What would you recommend?

Hello everybody

I need to buy a custom set of wheel for track racing.
Any opinions on https://www.carbonbikekits.com/ ?
They seem to do good stuff, and have a huge selection of rims to build the wheels. Also, good selection of spokes and hubs.
But they charge significantly for the handling fee, and they are not the cheapest version available.

That's why I'm asking for opinions, and recommendations for alternatives.

Thanks for pointing me out the drawing. I was looking in the specs, where the dimensions in the drops are not mentioned.
Well, this one might be a keeper... It's a bit too expensive for how heavy it is... but something else doesn't seem available.

Thanks again!

The og evkin has only flare, the syncros has outsweep and flare.
According to the dimension the og evkin is only 4cm wider in drops, mainly because it has a small drop of 115mm .
If only it wasn't so expensive i would have bought it, i feel a smaller drop more natural than 125-130mm where for me it's descending from third floor to cellar

This thing is quite interesting :

I didn't find any cheapest version anywhere.

they don't mention the distance in drops, but 16 degrees flare means, typically, 7-8 centimeters.
They seem to be a copy of (a copy of) Syncros Creston handlebar.

Hello

For those who own already an Airwolf YFR 066.
Is the front derailleur hanger riveted in the frame (so, unremovable), or fixed with some screws/bolts (so it can be easily removed)?

Hello

First of all, I want to thank you all for this wonderful place where I could find a lot of information that helped me a lot.

I'm looking for an affordable carbon frame, endurance geometry, not quite gravel, on which to move a GRX 800 1x11 transmission that I have from my son's CX bike (Canyon) which had its frame cracked after three seasons of intense usage. Now, he's quitting CX, and I have this transmission that I really don't want to sell - so what about building a road bike for me? (I also have the wheels - carbon, 35mm depth, 21mm internal, HG drive).

I was a bit reluctant to go the Chinese frame route, but I'm quite on a tight budget. Ideally, I'd buy a Merida Scultura Endurance frame (aprox 1350 Euro) and install my things on it, but it has clearance for only 35mm tires, I'd love 3-4mm more. Yet, the main deterrent is the budget.

The bike is going to be employed by me (47, not-very-fit, slightly overweight, who loved MTB - XC when I was younger and fitter).

So, I've narrowed down my research to Rinasclta Granite and, from this forum I've found out that Airwolf YFR066 is basically the same mold.
Then the big question (no 1) is: any reason to chose one over the other?

Budget-wise, the Airwolf might come cheaper for me (due to a mix of factors, including shipment to Romania, EU).
The main difference that I can notice is the carbon fiber employed: Airwolf employs Toray 1100, while Rinasclta employs a mix of Toray 800+1000.
What difference does this produce in ride quality? But in weight? On paper, the difference in weight seems almost negligible (for me) - approx. 100 grams more for Rinasclta. 
Another aspect that I might consider? Rinasclta have been quite responsive to my questions, and I didn't find many bad reports about their frame (some misalignments in headset spacers). Airwolf had some issues - from what I've read on this forum - both on delivery terms and specific problems).

Question no 2.
The bike that I intend to build will be 1x, with an Ultegra 8000 crankset and a 40T oval chainring. I don't need the front derailleur - but for the Rinasclta the front derailleur hanger is riveted - so, quite problematic to remove. I've talked to them, they could build the bike without it, but it would take a bit more, time-wise (not a problem for me). What about the Airwolf? Is it also riveted, or maybe it's attached via some screws that can be removed? (couldn't figure out from Aliexpress pics, they didn't answer me on Aliexpress (yet)). Also: any risk that I could not employ a 40T oval (not enough space for it)? I'm going to install it on the outside position of the crank.

Question no 3.
Any third candidate that I should consider, besides Rinasclta and Airwolf? Of course, in the same league, price-wise and provenience.
I'd like the bike to look more like a road bike than a gravel bike. I really don't like the look of those oversized forks with bosses for luggage. I don't need more than 40mm clearance for tires. And I want to employ different tires on the wheels, swapping them easily because I'd use TPU tubes (I already have a set of 30 & 32 for road, some 35 for light gravel - I might even acquire some 38s for special adventures).

Thank you all again!

P.S. Later edit - what I like about these frames is the geometry - I've ridden the Scott Addict that they copy (another piece of info found on this forum), and I really liked it.

Thanks for the replies!
I've seen xmcarbonspeed, but they don't ship to Romania. I'll have to see if any aliexpress dealer is trading their frames.
Good info about Sobato, I'll think about it, thanks!
My son is aprox. 1.45m, 8 yo. We're all quite tall in the family and he's going to grow fast. With the shortest stem, he will handle the M frame - I've made some tests. He's now riding a Specialised XS, 13,5 inch (aluminum frame) which fits him just perfectly.
The point is that I'd rather skip the S size, and jump directly to M.
The budget: a maximum of 500 USD, including the shipping.
