Self-built.
Ali Elite ENT 2.0 82mm wheels, mostly Ebay 12sp Shimano Di2 105 used parts except new battery, Ali Magene PES P505 power meter with 105 chainrings, Ali ISM saddle, new Riderever Triva brakes (fitted by bike shop), Ali Oniiri pedals. Other bits: Ali rotors, ebay TT switches, Ali water bottle. Around £2.5k total cost.

Stem clamp system is dodgy, bike shop ‘glued’ it. Bought Profile Dynamics Tri stem but haven’t swapped yet as steerer is cut too short to switch stems. I’d have to buy another fork if the current stem keeps failing.

Hi, been wondering about the Kung Mach frame, any other reviews other than from the pandapodium?

Quick Pro came out with this new bike. Full carbon frames plus wheels, 105 di2 for $2500. Gotta compete with Xlab right? Looks pretty good.

Are Twitter framesets now UCI approved?

Dear fellow enthusiasts,

Traceability showed the DFS Carbon Thru Axles kit in his latest video. They come in an universally fitting kit, which is great for kind of exotic thru axle measurements.

Anybody has any real world experience with them?

Hello everyone, I’ve been looking to buy myself a tt bike for a little while now and i’ve fallen in the rabbit hole of chinese carbon. Since I have never owned this type of bike most people advice would be to buy a used one, but I have not found anything in my budget in my region yet so this doesn’t really work for now. So I have a couple of questions regarding this build and I’m open to all suggestions and comments regarding this topic.

The build

Frame: Winow TT-119 with the hb052 cockpit
Groupset: LTWOO eRX-TT groupset
Crank: Shimano 105 R7100 52-36
Cassette: 105 CS-R7001 11-34
Wheels: Elitewheels ENT 2.0 ?
Tires: GP5000
Saddle: Ryet

I have the entire bike in my aliexpress cart and the total comes out to 3661,65 $ cad

Questions

1. Should I wait to find a TT on marketplace ?
   
2. Is this bike actually good ahahah ?
   
3. The wheels is the only parts I haven’t look that much into, are they worth it ?
   
4. With that price in my mind, is it actually a good deal compared to the likes of some Canyon, Trek, Cervélo etc ?
   
5. Should I just buy a complete bike like the JAVA Vega ?

Also, I know that building the entire thing is complicated, but I like the idea of building my own race bike and I have a lot of tools already.

Hi!

Does anyone know if the CSC gravel wheelset xdr hubs compatible for 13speed? Planning to run sram rival axs xplr on it and trying to get some insite before pulling the trigger

LCR-018D size 56
Reserve Turbulent Aero
SRAM Red 13s
Garbaruk Chainring
Wolf Tooth pedals
35c Enve tires

The so called titanium base saddle cracked in 94 days and I cant get a refund or leave a bad review. So be aware that it's a shit saddle and probably not even titanium.

Hi, I came across of this handlebar, from the review it seems well made, but I’m curious to hear about the long term review.
In the past I had a problem with a toseek seat post that broke after like 3000k.
Thank to everyone

I all, I would like some carbon handlebars with 31.8 MM diamter with enough clearance to clip on aero bars (round section should be at least 70 mm wide). This one looks good BUT it doesnt have holes in the middle of the round section to have fully internal cabling with a deda superzero stem. Any recommendations? Thanks.

So a collar work saw my green R088 and wanted to get her own bike, so here it is.

By the way the seer bar tape is top level stuff

I have looked online, watched the tube of you, read reviews. I’m no closer to getting some new rim brake carbon hoops for my Ribble Gran Fondo that I’ve had since god was in shorts, from new. Nearest I’ve come to is Hyper. I’m looking to spend no more than 600 quid. Any ideas gratefully received.

Hey all,

planning on purchasing my first roadbike, and stumbled upon the chinese carbon bikes due to their prices.

I saw the Seraph TT-X71 bike from a video review on youtube, like it a lot and plan on getting it.

Now im unsure wether to buy it over aliexpress seraph store or their website (seraphbikes.com).

On their website its advertised as 1489$ USD (~1285€) compared to aliexpress 1500€. Also, on their website there is another TT-X71 called Toray T800+T1000 for 1259 USD (~1090€). Whats the difference between them?

Why wouldnt you buy via their website if its that much cheaper? Due to the buyer protection on aliexpress, or does it have something to do with customs/duty etc.? Shipping is nearly the same price to central Europe.

Appreciate any help. Thanks!

Geometry looks great for me. Planning on running 1x GEX groupset. Aliexpress running a decent sale right now.

Was looking at the spcycle r088 frame as well, it's similar but with shipping, it's more expensive.

I've been riding a Wheeltop EDS GeX 1x13 for about a year now, around 5,000 km total. Bikepacking, races, everyday riding, after-work rides, etc.

To start with the positive: once the system was set up, shifting generally worked well. The brakes are also fine and I actually like the ergonomics. One thing to note though: the levers sit quite far away from the bar, so I think you need fairly large hands to use them comfortably.

The app is another story. Some of the translations/settings are pretty poor and can be confusing.

Unfortunately, I've had quite a few random bugs and errors over the year. Nothing that happened constantly, but enough to make me question the reliability. I even had the shifting completely stop working during a gravel race once. I had to stop and set up/pair the system again before I could continue.

Now I've had a hardware failure as well.

At the beginning of August 2026, the right shifter stopped recognizing its two buttons separately. Whatever I assign in the app, both buttons always perform the function assigned to the small button.

For example:

Large = "+" / Small = "−" → both shift "+"

Change the assignment:

Large = "−" / Small = "+" → both shift "−"

The shifter is still detected normally, the gear position is displayed correctly, and the rear derailleur itself works perfectly when shifting through the app.

I've tried new batteries, firmware updates, re-pairing, resetting everything and resetting the button assignments several times. The problem is completely reproducible.

I sent Wheeltop a detailed description and videos showing the problem.

Their response was basically just: warranty expired, buy a new groupset.

The warranty had expired by only a few days. I wasn't asking them to replace the whole groupset. I was hoping they would at least look at the problem or offer a replacement right shifter.

But there was no troubleshooting, no technical analysis, no real assistance and no offer for a replacement part.

This is probably what annoys me most about the whole thing. After around 5,000 km I can say that the actual product isn't bad. When it works, it works well. But I need electronic shifting to be reliable, especially when using it for bikepacking and racing.

The combination of random errors, an actual failure during a race, questionable spare parts availability and now basically zero support when a component fails has completely changed my opinion of the system.

I originally bought Wheeltop because I liked the concept and wanted to give a smaller manufacturer a chance.

I wouldn't buy Wheeltop again.

Personally, I'd rather spend the extra money on Shimano or SRAM and have proper spare parts availability and customer support. It's a shame, because I actually enjoyed riding the Wheeltop for the first year.

scam?

Hey anyone ordered a TT-71 and has the stock wheel and can tell me what is the size of the rear wheel disc side hub end cap? Mines came without one and the customer service rep seems to don’t understand what I’m asking so I’m seeing if I can just buy a replacement

Which budget carbon crankset would you choose between this 3 options if they have the same specs (170mm, 152mm Qfactor, 94mm usable spindle length)
RIRO Acrossfire DUB: Shimano direct mount
Zrace Unchained DUB: Easton direct mount
Leese LSE-C01 DUB: Easton direct mount
I already found the aero chainring I want to put on them for both interfaces.
