i agree with moments/or /tensiles…
maybe you could try koxx cranks too
i know the length on these are less than ideal for trials and really arent good when it comes to length, but you get a hub with em and their cheaper than new cranks so theymay be worth a try. i dunno. if you dont wana sepnd much money, then maybe give the used koxx a try, if you have money, then moments or tesiles no doubt. thats just me though
