How Much Weight Can Titanium Bolts Really Save?
Tom Bowers Cycling
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.
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.
- ...and 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.
- ...and 1 more
Key Points
- The reviewer used an 'S parts titanium bolts' kit designed for Dura Ace Di2.
- The main weight savings come from replacing steel bolts, not aluminium ones.
- The most significant weight savings were found on the brake caliper mounting bolts.

aliexpress.comAffiliate-Link by MyBikePartsThe 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.
Pros
- Shifting is really smooth
- The whole transmission works smoothly and freely
- Feels really nice and high quality in the hand
- ...and 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
- ...and 1 more
Key Points
- Installed on a Shimano Dura-Ace 12-speed transmission
- Used with an 11-speed chainring without issue

The BEST cassette on AliExpress!
Trace Velo
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.
Pros
- Extremely lightweight (122g)
- Unique, weight-saving two-piece construction
- Shifting performance remains perfect even after 1,000 miles of use
- ...and 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
Key Points
- Latest generation super lightweight cassette from AliExpress
- Construction: front sprockets are a single milled steel block, rear sprockets are a single milled aluminum block
- The two pieces are pinned together
- ...and 4 more
aliexpress.comAffiliate-Link by Trace VeloThe 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.
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
- ...and 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
- ...and 4 more
Key Points
- Model: Elitewheels Velo Six II (Vevel 6 version two)
- Cost: $1300 / ~£950 (with 15% discount available)
- Weight: 1628g for the pair
- ...and 12 more

I Ditched Dura Ace for Ltwoo ERX. Was It a Mistake?
Tom Bowers Cycling
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.
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.
- ...and 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.
- ...and 8 more
Key Points
- Model: LTWOO ERX (also called L2 V3, L2 ERX).
- Type: Semi-wireless electronic groupset.
- Speeds: Configurable via app as 2x11s or 2x12s.

- Material: Carbon fiber
- Finish: Two-tone carbon weave

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. Some YouTubers 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.
