Purchased: 2026-01-15

I've been running Goldix cassettes for the last year on several bikes and haven't had any problems with shifting, noise or durability so far. I've now got 2 x 10-36, 2 x 10-33 and have recently added a 12-speed 10-44, which also seems to work flawlessly. I also bought 10-36 and 10-33 Zrace cassettes in 2024 but the shifting is hesitant in some cogs which is not the case the Goldix ones. I'm still using Red cassettes on my best bikes, but these Goldix cassettes are about equal on weight and are proving to be great value for money.

These ones are fine - I have 1431 miles (2300 km) on them. The only issue is when I tried to take the spindle off of the right pedal body, it was on very very very tight. I was unsuccessful, so I'll have to go to more extreme measures when I need to service. So that's a bummer.

Quick update: I have to say I am quite impressed by these. 177g weighted. They are not clogged up with thick grease as the other ones, they spin very freely. Easy to setup. Haven’t tried with OG Shimano cleats, but the provided cleats work very well, they clip easily. Let’s see how they are long term. Will report back

I Made My 5.5kg BMC Even Lighter - Diminishing Returns Hit Hard

The reviewer is replacing their existing ZTO titanium/aluminum skewers with a new, lighter set of 'risk' skewers from AliExpress to save weight.

AI Summary

Pros

  • They are extremely light, weighing under 40 grams.
  • They are the lightest ones the reviewer could find.

Cons

  • The reviewer implies a potential downside of ultra-light skewers in general is that they sometimes lack large end caps, which these new ones might also have.
  • The reviewer notes they must be tightened down properly to avoid problems.

The reviewer discusses their experience with the ZTTO Ultralight SLR Gen 3 cassette, which they have purchased as a replacement for a previous ZTTO cassette that failed. They note it is a newer, supposedly improved generation.

AI Summary

Pros

  • Offers a massive weight saving (around 127g).
  • ZTTO has reportedly gone back to the drawing board to improve it.
  • The weight has been increased slightly from the first generation, which is theorized to improve durability.

Cons

  • The reviewer's previous first-generation ZTTO cassette failed 'pretty disastrously'.
  • They are skeptical about its durability, especially under high power (e.g., 450+ watt hill climbs).
  • They explicitly state they are not ready to endorse or recommend it yet.

I Made My 5.5kg BMC Even Lighter - Diminishing Returns Hit Hard

The reviewer mentions the Bigrock cranks as an upgrade installed in a previous video (part one). They state that the cranks were installed with their stock spider and a 4-bolt chainring, which was light but didn't save much weight versus their previous SRAM Red crankset. However, the Bigrock cranks did fix the chainline 'in a quite considerable way.' The reviewer notes the cranks are set up to work with 3-bolt SRAM direct mount chainrings, which allowed them to upgrade to a lighter E13 direct mount chainring for further weight savings and a cleaner look.

AI Summary

Pros

  • Fixed the chainline 'in a quite considerable way.'
  • Set up to work with 3-bolt SRAM direct mount chainrings, enabling a lighter chainring upgrade.

Cons

  • When installed with the stock spider and a 4-bolt chainring, it 'didn't save me much versus my SRAM Red crankset.'

They demonstrate the setup, app connectivity, route import from Strava, and navigation features.

The reviewer mentions the TOOPRE screwdriver twice. They first list it as part of the initial tool collection, describing it as a 'cross-head screwdriver'. Later, they discuss screwdrivers in general, noting that they are not used a great deal on modern bikes, but that the TOOPRE one would work for occasional home mechanic use. They compare it to a Park Tool JIS screwdriver they own, which they praise highly.

AI Summary

Pros

  • For occasional home mechanic use (once or twice a year), it is stated that 'this is going to work'.

Cons

  • The reviewer notes that screwdrivers are not used a great deal on modern bikes, implying limited utility.
  • They also mention that the TOOPRE screwdriver might be 'too big for a lot of stuff', suggesting a need for a smaller size as well.

The reviewer discusses a basic torque wrench from TOOPRE (referred to as 'two pre' in the transcript). They describe it as a manual tool that provides an indication of torque by flexing a handle, rather than being a highly accurate click-type wrench. They test it on a stem bolt, comparing its indicated 6 Nm setting against a preset Park Tool torque wrench, and find it to be reasonably close. The reviewer positions it as a tool for home mechanics who need a basic guide to prevent overtightening, rather than for precision work.

AI Summary

Pros

  • Provides a good indication of torque to prevent overtightening bolts.
  • Suitable for occasional home mechanic use.
  • Comes with a selection of bits, including some Torx bits.

+1 more

Cons

  • It is not going to be 100% accurate.
  • It is described as 'nothing like' a digital or professional click-type torque wrench in terms of precision.

The reviewer mentions a 'pedal spanner' as part of a collection of AliExpress tools being tested. They state it is basically a 15mm spanner that is thinner on the end to fit behind pedal cages and longer for leverage. They use it to remove a pedal, noting it works without issue. They compare it to their usual Weiha brand tool, noting the main difference is the length, with the Weiha offering more leverage. They conclude the AliExpress version does the job perfectly well.

AI Summary

Pros

  • It is thinner on the end to get in behind pedal cages.
  • It is longer than a standard spanner for more leverage.
  • It works without any problem for removing pedals.

+1 more

Cons

  • It is shorter than the reviewer's preferred Weiha brand tool, offering less leverage.

The reviewer discusses an internal routing kit tool, which they mention having multiple versions of from different manufacturers. They describe it as a kit containing various gadgets and ends for routing internal cables and hydraulic hoses. They state it is useful for situations where liners were not left in the frame during disassembly or when building a new frame. They note the kits can be fiddly but are effective for getting out of trouble. They also mention that the components from different kits are often compatible, allowing one to build a comprehensive collection.

AI Summary

Pros

  • Super cheap
  • Really really good kit
  • Will get you out of trouble

Cons

  • Can be a bit fiddly

The reviewer mentions a set of pliers as part of a home mechanic's toolkit sourced from AliExpress. They briefly demonstrate the set, which includes long nose pliers, standard pliers, and side cutters, and state that such a set is useful for various tasks in a workshop, like using pliers to remove a valve adapter or side cutters for cable ties. They do not provide a detailed review or specific performance test of this exact 3-piece set.

AI Summary

Pros

  • The reviewer states you definitely need a set of pliers for various tasks in a workshop.
  • They mention the set includes long nose pliers, standard pliers, and side cutters, covering different uses.

Cons

  • The reviewer notes that when trying to cut a spoke with the side cutters, it was a struggle and 'you're going to break your hand,' indicating they are not suitable for heavy-duty tasks like cutting spokes.

The reviewer states that the TOOPRE Bicycle Wheel Set Center Bow Wheel Center Positioning Gauge Calibration Wheel Bow Adjustment Tool is used for calibrating a wheel truing stand. They mention it is used to center the stand's arms between the gauge's bits to ensure the stand is calibrated. They note it is about a tenth of the thickness of the official Park Tool gauge, but they cannot see how it wouldn't work for the amount of times it is used. They previously had the original Park Tool version but sold it to buy more tools, then bought this TOOPRE one instead, which they felt was a better investment.

AI Summary

Pros

  • It works for calibrating a wheel truing stand.
  • It is a much cheaper alternative to the official Park Tool gauge.
  • The reviewer considered it a better investment than keeping the more expensive tool.

Cons

  • It is noted to be about a tenth of the thickness of the official Park Tool gauge.
