Tacx Sirius Cycle Trainer

newbie hybrid

Hi, HELP PLEASE. I've purchased the above trainer. The dropout on my wheel is 135mm but I can only get the spacing on the trainer down to 165mm. Currently emailing to and fro supplier with no sucess so far. I'm an injured ex-runner desperate to use my trainer. Would be really, really grateful for some advice please!! My cycle is a Rayleigh Pioneer Classic Ladies hybrid cycle. Could there be a part missing. Thought I read somewhere that hybrid cycles might need another part to fit cycle trainers.Thanks
