- Help me identify these cranks please.
Hi trying to build a decent budget bike for my lad and want to use a suitable length crank set.Posted 6 years ago
On the isla bike pictured there using 152mm cranks with a single 28 tooth ring mounted without a spider. Im thinking its possibly a BMX set up but i dont know anything about BMX cranks. Anyone recognize it?
Hi scaredy i saw the on at EBC and its well priced but wanted to go for the single ring for low weight and simplicity. The one in the picture looks like the chain rings are riveted on so not easy to get a 28 tooth ring on.
Nwill. He has have a 24″ isla now. I think hey just hand pick parts that are most suitable for kids sizing, I doubt they have had cranks forged to their specifications.Posted 6 years agoiain1775Member
Only listed as Islabikes 152 – http://www.islabikes.co.uk/bike_pages/pdfs/product_specs/Creig26.pdf
In past on other models Islabikes have used Prowheel cranksPosted 6 years ago
Isla bike say its their own crank.. I’ve not found a shorter crank that will take anything less than 36t yet.. I was going to see if I coudl buy one direct from Islabkes, but 152mm is still too long for what I’m looking for. At 152, you could shorten a 40 quid SRAM S600 – http://bikesmithdesign.com/Short_Cranks/s600.htmlPosted 6 years ago
Hi they arrived today, so pretty fast delivery. The crank arms look like there forged from a standard blank so yes they could be shortened a bit maybe 10 or 15mm max. The chain ring is alloy but broached onto the crank arm so not easily changed. I will put them on the scales tomorrow.Posted 6 years ago
They are square taper by the way.
