BXT GRAVEL-135

BXT GRAVEL-135

Frame
Cus Baker on YouTubeabout 1 month ago
£319 Carbon Gravel Frame — Bargain or Big Mistake?

The reviewer purchased a BXT gravel bike frame for approximately £300 after searching for the cheapest options. They unbox and examine the frame, noting it arrived in 4-5 weeks. The packaging was basic but protective. The frame is a matte-painted carbon model called the 'Gravel 135' with a UDH rear derailleur hanger, includes a seat post, handlebars, fork, and all necessary accessories like a thru-axle, bearings, and seat clamp. They are generally impressed with the initial quality for the price, noting the carbon weave is visible, the frame feels solid, and it has 50mm tire clearance. However, they note minor issues like paint overspray, a questionable headset bearing measurement printed on the frame, and a potentially loose bearing fit. They plan to build it with parts from their current bike to test ride it.

AI Summary

Pros

  • Very affordable price (around £300)
  • Comes with all necessary accessories (handlebars, fork, seat post, thru-axle, bearings, seat clamp)
  • Frame feels nice and solid upon inspection

+8 more

Cons

  • Basic packaging with no 'fragile' markings and a hole in the box
  • Some paint overspray on the bottom bracket area and the thru-axle
  • Seat post looks a bit thin and lacks measurement markings

Screws
How Much Weight Can Titanium Bolts Really Save?

The reviewer does not specifically mention the 'SPARTS bicycle disc brake titanium screw for shimano R9270 brake system titanium bolt nut' as a distinct, named product. The transcript discusses a general 'S parts titanium bolts' kit designed for a Dura Ace Di2 groupset, which includes various bolts for components like brake calipers, derailleurs, and shifters. The reviewer installs and weighs these bolts throughout the video, focusing on weight savings and durability compared to stock Shimano hardware.

AI Summary

Pros

  • The titanium bolts for brake caliper mounts offer a 'massive' or 'huge' weight saving (e.g., stock 13.9g vs. S parts 6.1g).
  • Titanium is 'significantly stronger than aluminium' and 'more corrosion resistant', making bolts less likely to seize or round out.
  • For certain parts, like the front mech bolt, the S parts kit is specifically designed for Dura Ace, providing the 'perfect size' where generic titanium bolts might be too long.

+3 more

Cons

  • For parts where Dura Ace already uses aluminium, swapping to titanium can actually increase weight (e.g., rear derailleur B-bolt: stock 3.0g vs. S parts 4.1g; pad pin: stock 0.7g vs. S parts 1.0g).
  • The overall weight saving from the full titanium overhaul is minimal (estimated 30-40 grams), which is within the margin of error of the scales.
  • The cost is high ('nearly 100 quid'), making it hard to justify for weight savings alone.

How Good Is The Aliexpress OSPW (Ceramicspeed?)

The reviewer discusses an AliExpress OSPW (Oversized Pulley Wheel) system, which is a generic or unbranded alternative to the Ceramic Speed OSPW. They installed it on a Shimano Dura-Ace 12-speed rear derailleur with an 11-speed chainring. They state the shifting is smooth, the transmission works smoothly and freely, and the part feels high quality and spins nicely. Installation was easy by following the original Ceramic Speed tutorial. The only issue was a small gap causing chain rub in extreme cross-chaining (big-big gear). They note it is a stylish, closed jockey wheel design that actively removes debris.

AI Summary

Pros

  • Shifting is really smooth
  • The whole transmission works smoothly and freely
  • Feels really nice and high quality in the hand

+6 more

Cons

  • Had a small gap between the chain and inner plate causing rubbing in extreme cross-chaining (big chainring and big rear cog)
  • Lacks the quality control, warranty, and support of a brand like Ceramic Speed
  • Uncertain what quality the ceramic bearings are or how long they will last

The BEST cassette on AliExpress!

The reviewer analyzes a super lightweight cassette from AliExpress, which is the ZTTO Ultimate model. They describe its unique two-piece construction, with the front sprockets milled from a single block of steel and the rear sprockets milled from a single block of aluminum, pinned together to save weight. They weigh it at 122g and compare it to a heavier, standard 11-34t steel cassette. They note they have used an identical gold version for about 1,000 miles, showing visible wear on the aluminum teeth but with shifting still perfect. They caution that durability is a trade-off, as the aluminum teeth will wear quickly if used frequently in hilly terrain. They mention the price has dropped since launch, and they purchased it for just over 60 pounds.

AI Summary

Pros

  • Extremely lightweight (122g)
  • Unique, weight-saving two-piece construction
  • Shifting performance remains perfect even after 1,000 miles of use

+1 more

Cons

  • Aluminum rear sprockets are softer than steel chains and show visible wear
  • Durability is a concern, especially in hilly areas where the larger aluminum cogs are used frequently
  • Will wear through quite quickly if used often in hilly terrain

Giving these wheels a second chance - Velo Six II

The reviewer tests and reviews the Elitewheels Velo Six II (Vevel 6 version two) wheel set. He states that the primary issue with the original version was poor lateral stiffness, which has been significantly improved in version two, making it nearly three times as stiff without added weight. The wheels are one-piece carbon, 50mm deep, with a 21mm internal width, weighing 1628g. They are designed for triathlon and road riding, offering high aerodynamic performance, a very stiff and responsive ride, and a distinctive, loud freehub sound. However, the ride is harsh on rough roads, and they are susceptible to crosswinds. The reviewer has ridden them for over six months and praises the bearing durability and anodized aluminum axle. They are not UCI-legal for road races.

AI Summary

Pros

  • Looks great and is a head-turner
  • Significantly improved lateral stiffness in version two (nearly 3x stiffer than original)
  • No weight increase despite stiffness improvement

+10 more

Cons

  • Lateral stiffness was a major issue in the original version
  • Ride is harsh on rough roads due to zero vertical compliance
  • Catches crosswinds due to large side profile, which can be unnerving

Are Cheap Chinese Road Bikes ACTUALLY Worth It? (being 100% honest…)

The reviewer discusses the Sava A7L Pro as a primary example of a high-value Chinese road bike. They compare it directly to their Trek Domane SL5, highlighting its significantly lower price and many comparable or superior features. They detail their personal experience with the bike, including initial quality control issues upon delivery and the positive resolution from Sava's customer service. The reviewer uses the Sava A7L Pro to illustrate the broader value proposition of Chinese bikes.

  • Significantly cheaper (cost $1,500 vs. $3,500 for the Trek Domane SL5)
  • Comes with a carbon frame
  • Equipped with a Shimano 105 groupset

+8 more

Cons

  • Quality control issues upon delivery: damaged handlebar tape, a cut in a rubber hood sleeve, and a paint chip near the fork

I Ditched Dura Ace for Ltwoo ERX. Was It a Mistake?

The reviewer purchased and installed the LTWOO ERX (referred to as L2, L2 V3, L2 ERX, and ERX) electronic groupset on a winter training bike, replacing Dura Ace Di2. They tested it for approximately 5 months. The reviewer states the rear shifting is fast, reliable, and crisp, comparable to other electronic groupsets. The front shifting is noted as noisy, clunky, and slow, reminiscent of older generation products. The app offers extensive customization, including selecting 11 or 12-speed operation and micro-adjusting individual sprockets, but the initial setup was challenging with a default Chinese language setting. The groupset uses a semi-wireless design with USB-C charging via the front mech, which is praised, and battery life is reported as good. The brakes require non-standard adapters for flat mount frames, which the reviewer dislikes. The groupset is significantly heavier than Dura Ace, comparable to Shimano 105. The price is a major advantage, coming in considerably cheaper than Shimano 105 Di2 when factoring in additional drivetrain components. The reviewer concludes it is a solid competitor to 105 Di2 for tinkerers and self-builders, but has compromises compared to top-tier groupsets.

AI Summary

Pros

  • Rear shifting performance is fast, reliable, and crisp.
  • Extensive app customization: can be set to 11 or 12-speed, micro-adjust individual sprockets.
  • USB-C charging via the front mech is convenient and uses a universal charger.

+6 more

Cons

  • Front shifting is noisy, clunky, and slow, not on par with Dura Ace.
  • Brake calipers use a non-standard mount requiring ugly adapters for most flat mount frames.
  • The groupset is heavy, comparable to Shimano 105 level, not lightweight.

The reviewer is building a QuickPro GR1 frameset, which was sent for review by QuickPro USA. They describe it as a carbon gravel frameset with a two-tone carbon finish. The reviewer mentions the frame is aerodynamic, has high-quality carbon, and includes features like a threaded bottom bracket and internal cable routing. They note that QuickPro USA fixed a previous issue with the headset spacer gap on this model. The frameset comes with a seat post, seat post clamp, and headset parts, all nicely labeled. The reviewer built it up with various components and tested it on gravel, stating it handled amazingly on aggressive terrain.

AI Summary

Pros

  • Aerodynamic design
  • High-quality carbon construction
  • Two-tone carbon finish looks nice

Cons

  • The reviewer initially brought the wrong seat post clamp (for Di2), delaying the build
  • A headset spacer issue existed on a previous model (AR1) but was fixed for this one
