The reviewer states the full name for the frameset is the 'Ulio G21 Alterara gravel frame set' and later refers to it as the 'Altera' and 'Alterara'. They describe it as UCI approved, robust and strong, though not the lightest frame available. Key features highlighted include the T47 threaded bottom bracket, UDH compatibility, two storage compartments, mudguard/fender mounts, and clearance for up to 53mm tires. The reviewer compares it to the older Yolio G21 model, noting differences like the round seatpost, updated bottom bracket standard, and added storage. They praise the quality of the threads, prep work, and included manual, concluding it is a good option for a durable, bombproof gravel bike for off-road enjoyment rather than serious racing.

Pros

  • UCI approved frame and fork
  • Robust and strong construction
  • Nice chunky rear stays and dropouts
  • ...and 13 more

Cons

  • Not the lightest frame out there
  • The price is not the cheapest on the market

Key Points

  • Full name: Ulio G21 Alterara gravel frame set
  • UCI approved
  • Color: Champagne

Forum Discussion on 2025-08-24

I must have gotten lucky with my set. Perfect fitment and 0 leaks. I don't have to over tighten. I can shake bottle upside down and no leaks. Even a light squeeze removing the bottle when full doesn't squirt out. The flow of water is comparable to my old specialized bottles I have

The reviewer discusses TPU tubes from AliExpress in general, not the specific RideNow TPU Bike Inner Tube model. They state that TPU tubes are the lightest, strongest, and most packable insurance policy for flats, even with tubeless setups. They found a deal for two tubes, tire levers, and a patch kit for $12, which is significantly cheaper than brand-name alternatives like Pirelli. The tubes are available in various sizes for road, gravel, and mountain biking and are small enough to be left in a repair kit indefinitely.

Pros

  • Lightest
  • Strongest
  • Most packable insurance policy for flats
  • ...and 4 more

Key Points

  • Material: TPU
  • Price: Approximately $10 each, or $12 for a kit with two tubes, levers, and a patch kit
  • Sizes: 700, 650, road, gravel, mountain

The reviewer discusses a 3D printed saddle purchased from AliExpress as a budget alternative to brand name versions. They mention having ridden one for the last 2 years and purchasing another one, which they see as a strong testimonial. They state that these saddles are weatherproof, just as comfortable as the premium versions, and note the irony that the 'fake one' is lighter in weight than the 'real one'. They encourage viewers who have purchased one based on a past video to share their experiences in the comments.

Pros

  • Weatherproof
  • Just as comfortable as premium saddles
  • Lighter weight than the real/brand name version (in their specific comparison)
  • ...and 1 more

Key Points

  • 3D printed
  • Purchased for $45 (current price mentioned, down from $65 a couple years prior)
  • Ridden by the reviewer for 2 years

"Why risk buying cheap stuff from abroad?"

We love new bike tech and follow bike brands extensively. Riding bike can be a very price intensive thing, but it can be made more accessible by saving some money, and spend it on the parts that matter mostly for you. After a couple of thousand kilometers, most buyer can determine the quality themself. YouTubers, like TraceVelo already have a successful history with using cheaper parts from Aliexpress or eBay. To crowdsource those experiences, we've made this site, to seperate the wheat from the chaff. To be honest, there is also a lot of crap or mediocre stuff out there, but at the same time you can find reliable and quality stuff.
