I'm looking to get a fluid trainer so I can add a 3rd day of saddle time + winter rides. Since I don't have quick-release hubs, I'm having issues finding a fluid trainer that will actually hook up. Am I stuck with a mag trainer?

Thanks!

Fluid and mag are two different ways of providing resistance and are not related to how the bike attaches. I don't know of any trainer that either doesn't capture the ends of a (special) QR or replace the rear wheel itself like the Lemond or Kickr.

An alternative you might consider is rollers.

Yes, as Loogi points out, the type of resistance (fluid, magnetic) doesn't matter to how the bike attaches, and most trainers that use your bike's wheel will capture the ends of whatever is clamping your wheel in the dropouts, be they bolts or a quick release.

What's clamping your wheel?

Sorry.. Should have given more detail.

At the moment I ride a Denali, and my wife a Roadmaster so neither bike has QR hubs. I've been looking around and I would much prefer a fluid trainer for extra saddle time. Thing is, all the fluid trainers I've found only have QR hookups (unless I'm missing something). I have found mag trainers that allow for a bolt-on wheel. So, has anyone heard of a fluid trainer that will attach to a bolt-on wheel, or am I stuck with a mag trainer?

*edit* I'm not looking to swap to QR hubs at this time. Honestly, I don't want to dump the cash into this bike when I plan to upgrade for the 2016 tri season
Again, sorry about being so vague in the OP

It's not clear why you couldn't use your bike in a normal trainer. I don't think the outside diameter of all QRs are the same so the bolts extending past the frame should fit within the holes of the trainer ends. As long as you tighten the trainer properly it should work. You don't need any precise alignment.

edit: Alternatively, you could buy a couple of Acorn nuts (McMaster-Carr) of the appropriate size and put them on the ends of the axle. The nuts look very similar to the ends of a QR.

Yea they are for better bikes than what you own.. they would have a QR end cap on both ends ..

Maybe you can find some Acorn nuts ( good ones, Machined , not the cheap ones that just use a sheet metal dome on the end )

increasing the width .. fattening the ends

or have the whole axle assembly replaced by a QR axle * so it has those ends that the makers of Trainer stand presumes the bike would use

*a job a Bike shop can do , when you bring the wheel in they can see what you have..

maybe a substitute wheel would be simpler .. get one with a QR axle ..

There are polyureathane foam tires that have as their side effect heavy rolling resistance .

But if a workout is your goal, that will add to the workout resistance.

Hehehe I am quite aware that of the quality of bike that I own. I like weirding out the guys on "B" rides when they can't drop me.

I'm liking the acorn nut idea. Going to have to look into that. I really don't want to spend the cash on a wheel just to have it go away when I upgrade bikes. I have one sprint tri left this year, 3 planned for next year. In '16 when I start pushing Oly distances is when I'll upgrade and unless I retire the Denali to pure trainer status, it'll get passed to someone else needing to get on the road.
