What crank is this

[Deleted member 26715]

I believe it is a 2006 Decathlon Rockrider 8.1 there is play in the crank what kind is it & can it be replaced.

Possibly a square taper with bolt/washer, best way to find out is remove one of the allen bolts and washer, but looks like it to me.

The play will be in the bearings/bb more likely, have you tried totally undoing the bolts then re assembling?

It just looks an unbranded pressed affair to me.

Crank length permitting I don't see why you can't fit any compatible square taper triple TBH, something like THIS maybe with a new UN55 BB?

Shimano Alivio FC-M431 I believe - probably square taper (they do an OctaLink version also, I think)
They're available in 44-32-22 or 48-36-26

If it's the square taper Rose Bikes do them cheaper than most - http://www.rosebikes.co.uk/products...ccessories/mtbatb-cranksets/mtbatb-cranksets/

Square taper cartridge.

Need to remove both Allen bolts, get a crank extractor and a square taper BB remover and a big spanner.

play in crank would be bottom bracket.

the chainrings are worn - it'll be more cost effective to buy a replacement BB instead of getting a set of rings.
