Venugopalan Bct-sl-005 review

A drivetrain cleaning kit with an enclosed chain scrubber, twenty microfibre ropes, brushes, and both a cleaner and a lubricant.

Our conclusion The most complete kit on this page: an enclosed chain scrubber with rotating internal brushes, twenty microfibre cleaning ropes for the gaps between sprockets, a set of brushes, a sponge, a towel — and the two fluids that actually get used up, 350 mL of chain cleaner and 60 mL of all-weather lube. $36.99, and the only kit here that answers this shelf’s buying advice with a yes.

What you are getting

A drivetrain kit built round an enclosed chain scrubber with multiple internal rotating brushes, plus 20 microfibre cleaning ropes, specialized brushes, gear cleaning tools, a sponge, a microfibre towel — and the fluids: 350 mL of chain cleaner and 60 mL of all-weather chain lubricant. 862 g (30.4 oz). $36.99.

The scrubber is the point of this shelf, and this is one

“The enclosed bicycle chain scrubber uses multiple internal rotating brushes to clean around chain links as you rotate the drivetrain, helping loosen built-up dirt, grime and residue without removing the chain.”

The tag on this page is that a chain scrubber does in two minutes what a brush does in fifteen, and the reason is geometry: a chain has four surfaces and the inside of its rollers, and a brush in the hand reaches two of them. A closed box with brushes on every face reaches all four as the cranks turn.

Of the five kits already published here, the Dr. Wack is two brush heads and the Muc-Off a bucket of cleaner and brushes. A proper enclosed scrubber is what this adds.

It includes the fluid, which is what this shelf’s buying advice asks

“Check whether the advertised kit price includes the degreaser. Kits that look far cheaper than their neighbors are often brushes only, and the fluid is the part that gets used up.”

This kit includes 350 mL of chain cleaner and 60 mL of lubricant.

Three of the five published kits are brushes only. This is a kit with both halves, and $36.99 is the price of both halves.

What it does not publish is a top-up price for either fluid, which is the recurring cost — the degreasers page on this site is where a 473 mL or 1 L replacement comes from.

Twenty microfibre ropes, a tool shape the shelf had not compared

“The included 20 microfibre cleaning ropes reach between cassette cogs, gears and narrow drivetrain gaps.”

The introduction to this page compares brush shapes — “a narrow cassette brush and a soft frame brush do different jobs”. A rope is a third shape, and it does something neither brush can: it goes between two sprockets, where the gap is a couple of millimeters and the grime is thickest.

Twenty of them is a consumable count rather than a tool count: a rope used between a cassette’s cogs comes out black and is thrown away. Twenty is perhaps four or five services.

The puncture repair kit page on this site has the same idea in another niche — the XIAOCUNCN kit includes five cleaning floss strips.

And then a sponge and a towel, which is the whole-bike half

“The sponge and microfibre towel complete the job for convenient whole-bike cleaning.”

That is the second half of the distinction the degreasers page on this site is built on: a frame cleaner and a drivetrain degreaser are different products, and a frame needs a sponge rather than a stiff brush. This kit spans both jobs.

What it does not include is a frame cleaner — the 350 mL is a chain cleaner. For the frame there is water and the sponge, or a bike wash bought separately.

60 mL of lubricant is a starter, not a supply

Sixty milliliters against the bottles on the lubricants page of this site: Finish Line Dry 237 mL, Muc-Off Bio Dry 120 mL, WD-40 Wet 118 mL.

So the lube in this box is between a third and a half of a normal bottle — enough to finish the first clean and a few after it. “All-weather” places it as the compromise type, which is what the three lubricants already published on that shelf are.

And one claim is doing no work

“Without buying multiple products separately” appears in the first bullet, and “a versatile bike cleaning kit for mountain bikes/MTB, road bikes, gravel bikes, e-bikes, commuter bikes and more” in the fifth. A cleaning kit is indifferent to the kind of bike; listing five is search padding.

What is not published

No scrubber capacity, which decides how often the solvent inside has to be emptied; no brush count or shapes, only “cleaning brushes” and “gear cleaning tools”; no bristle material, where the LEWBDF kit published here names PVC and nylon and the intro to this shelf asks how bristles hold up against degreaser; no refill price for either fluid; and no indication of whether the scrubber seals well enough to use indoors.

What we rate and what we flag

Strengths

  • An enclosed scrubber with brushes on every face, which is what this shelf is about
  • Includes both fluids, where three of the five published kits here include none
  • Twenty microfibre ropes, the only tool shape that fits between two sprockets
  • A sponge and towel too, so the frame is covered as well as the chain

Compromises

  • No scrubber capacity, so emptying frequency is unknown
  • No brush count, shapes or bristle material
  • 60 mL of lube is a third of a normal bottle
  • No refill price for either fluid, which is the recurring cost

The questions riders ask

Why is a scrubber better than a brush?

Geometry. A chain has four outer faces plus the inside of its rollers, and a brush held in the hand reaches two of them at a time. An enclosed scrubber has brushes on every face and runs the whole chain past them as the cranks turn — which is what the tag on this shelf means by two minutes against fifteen. Of the five kits already published here, only one has anything like it; the rest are brush sets.

Does the price include the degreaser?

Yes, and that is the question the buying advice on this shelf tells you to ask: 350 mL of chain cleaner and 60 mL of lubricant are in the box. At least three of the six kits published here — the Aoreun, the LEWBDF and the Dr. Wack — are brushes only, which is exactly the case that advice warns about. What this listing does not give is a refill price for either fluid, and the fluid is the part that runs out.

What are the twenty ropes for?

The gaps between cassette sprockets, which are a couple of millimeters wide and hold the worst of the grime. No brush shape fits there — the introduction to this shelf compares a narrow cassette brush and a soft frame brush, and a rope is a third shape that does what neither can. They are consumables: one comes out black and is discarded, so twenty is four or five services rather than twenty.
