Tacx Sirius Cycle Trainer - help

newbie hybrid

I have a problem with the set up of the above trainer. My cycle has rear dropout of 135mm but the smallest I can get the spacing on the trainer is 165mm. Can anyone advise please?

Are you using the Tacx QR skewer that came with it?

Thanks for your reply.Hi, my cycle is a rayleigh pioneer classic ladies cycle and is does not have a quick release on it, my husband said he has not tried it as he feels once it is screwed onto my cycle he does not think it will be any wider than what we have already. Your view on this would be appreciated - thanks.

Sorry I don't know anything about your bike specifically but AFAIK you need to use a QR skewer as that's what the turbo is designed for. I suppose there will be a work around but I don't know it. If you don't get joy here maybe post in Workshop or even Training.

The 135mm refers to the inside distance between the dropouts? That's standard for a lot of bikes. There should be no problem fitting that to your trainer with the QR skewer that came with the trainer as I have exactly the same.

Normally there is good reason to use the quick release as it is made of steel and is much stronger than the aluminium QR skewers that are normally on bikes. Because you are securing the bike into the trainer through the skewer it needs to be strong. However as you do not have a quick release axle you may already have steel axle.

Depending on the diameter of the axle in there, it may cause difficulties as the non-quick release axles (in my memory) have a larger diameter than the normal quick release ones and the skewer that you get with the trainer assumes you are replacing a standard quick release axle. Others here may have some better info on this than me as to whether it would be a problem.

Thank you both very much for your replies. We will look again at the trainer this afternoon following your comments. Much appreciated. I'm an injured ex runners with no experience of cycle trainers - thank you.

Tacx do special axle nuts for non qr axles for use on their trainers:

Thank you all for your comments - we feel you have now answered our query - thanks very much. I actually bought the cycle trainer from chainreaction and we have been emailing back and forth these past few days to try and solve our query. I will now contact them again and ask whether the axle nuts are what we need. Will update with their reply. An excellent, friendly and helpful forum with no condescending comments to someone not part of the cycling fraternity - Thank You!

Should just be a matter of measuring the axle stub for the correct size. My trainer bike has nuts but I ended up with an ELITE trainer which has huge cups that just slotted over

Tacx run and monitor this forum, and i have found their tech support very good

Contacted Tech support at chain reaction cycles and the person we spoke to did not know that they stocked Tacx axle nuts for bikes and did not know what they were for. He advised us to use the quick release skewer, even though my cycle does not have a quick release rear wheel, but we are not able to remove our axle, so we are thinking the only way to go is to use the axle nuts, which has has been recommended on the forum here. Unsure whether to spend a further £16.99 when we can't get confirmation from them that it's what we definitely need.

Just get them mail order and you can return them for a refund if they are not the solution. You should be able to tell without fitting them but they appear to be made for just your situation.
