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.

- 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

- UCI approved
- Color: Champagne
- ...and 12 more

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

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.
