CNC'd from full length cranks then hand finished.
At last a triple crankset for children with a sensible length.

NOTE: New old stock, some of these cranks have light scratches but this is purely cosmetic and does not affect the performance of the product.

Solid But Need Better Finishing
12 Aug 2016
4 / 5
I recommend this product
ConsFinishing is a bit substandard
ProsGood kids length, twist looks nice
These cranks are solid and look like they're built strong enough for an adult user (or will survive successive kids abuse). Th TA ring that I mounted fit well with not play on the shelves of the crank, as did the Thorn bashguard.
The only gripe I have is that the finishing on the edges and threads of the crank needs more work. There was a 15mm long spiral shard of metal coming out of the drive side thread, which came off easy enough, and most of the edges of the spider were sharp enough to feel a bit dangerous handling. Its something that 3 or 4 passes with a file (in 15 or so spots) fixed.

Are these just for kids or strong enough for an adult rider ?
17 Aug 2017
Specifically an 85kg adult rider who likes to stand on the pedals up hills, but needs very short cranks because of a knee problem.

These cranks are strong enough for adult use as well.

Will This Fit A Jis Bottom Bracket?
16 Apr 2016
I have a 2016 Brompton, and would like to see if this will fit on the existing BB. The BB is JIS 119 mm, possibly is this one:

If not can you recommend a BB ?

These cranks can indeed be used with a JIS bottom bracket.
