MTB Cranks & Chainrings: Middleburn, Grafton, Surly REDUCED

Grafton Speed Sticks 175mm Cranks 110 BCD

Lightweight MTB cranks with some scratches that probably won't polish out but otherwise in good shape.

These unusual cranks were made for one year only in 1991 when they cost $200, although a different version was later marketed by the manufacturer Precision Tooling as Topline cranks. These first generation examples are machined from aerospace grade (ie super strong) 7075-T6 aluminium/zinc alloy. The drive side weighs 250g and the non-drive arm 190g. JIS square taper axle fitting. Comes with allen bolt fittings.

Now £50 posted.

Pretty sure closed back of pedal thread = Topline, no?

Sent PM re Middleburn.

Topline is a later brand name from the same manufacturer

Nope, different brands, different workshops, Graftons never had the closed pedal end. Regardless, they are nice cranks and the price is good, I’m just being petty.

Pm re Grafton

I might being daft, but just out of curiosity, how the hell do you get pedals on these Grafton cranks?! EDIT Am being daft, saw the second photo not the first.

No need for pedals, they turn of their own accord drawing energy from a secret source.

Sold! An eBike without having to be seen on an eBike!
