Tranzx Indoor Trainer

So winter is coming and it’s getting wetter and darker outside.  For me this means that the opportunity to ride is slowly closing on me and limited to riding on weekends or on dry nights.  That’s one of the big things when riding the Mendota, it’s an interesting experience when things start getting damp.  Full wet/rain is fine; you know what you are going to expect when start the ride and it cuts through the rain soaked roads fine.  The big problem is when it’s damp and greasy.  Unfortunately that’s what the conditions are heading to at the moment.  When it’s like this it’s easy to fishtail the bike around corners; it’s doesn’t feel great under breaking either and what ever you do, stay away from those lines.  I think this is more down to the Syndey roads that anything else.  It doesn’t rain for long enough for the grease to really clear and that first patch of rain just seems to bring up more grease on the road.  So..what to do that I can keep the riding fitnes up?  I thought a trainer might be in order and Torpedo7 just happened to have one on offer.

Thanks to Torpedo7’s sale/bargains that come up regularly I picked up the Tranzx Indoor Trainer for $100 including postage.  I’ve thought about getting one of these for a while.  It’s two fold really, the first is a fitness thing and second is just being able to train on my bike and not the gym one.    I was slightly weary about this as one of the reviews came back with “not enough resistance“.  Then again, am I looking for resistance here rather than just full spinning training?  It should give some resistance no?  But for the price, I went ahead and got it and a few days later it turned up.

It arrived in a largish box and weighs around the 10KG mark, so not too heavy and easy to carry home.  It’s well packaged with easy clear instructions, but the whole thing is kind of obvious as to how it you put it together.  The only thing you need to do is change the quick release skewer on the bike with the replacement quick release skewer.  The replacement one is larger and more rounded on each end.  This makes sure that it’s a perfect fit into the trainer ( you don’t want it to fall out of place when you are cycling on it).  After you’ve done the replacement, simply attach the bike in place using the large handle to clamp it down and you’re up and running.  The resistance can be increased by turning the screw that the roller at the back sits on.

So how is it?  Well, not too bad.  The first time my tires were a bit flat, so it felt very easy.  Back up at 120PSI and a couple turns on the screw and it’s pretty good.  The frame is solid and you aren’t going to be moving off anywhere that’s for sure.  It’s not overly big so, taking up room is not a concern and the new skewer really does  hold you in place.  The resistance is on the lower end, or at least so I thought.  You can get it to a level that it feels like you are on a long straight road with maybe a slight incline.  This does not seem much at first, but then you spend 30minutes on the thing.  That’ 30minutes of turning and no free wheeling.  There’s a burn that’s for sure.  You can’t let up as soon as you do the rear wheel stops so you can’t freewheel at any time. So you pedal and you get into a rhythm quick quickly.  I guess this is more to do with that it’s you’re bike, so there is no adjustment time.  It’s noisy though.  The mixture of your wheel spinning and the magnet spinning around creates a lot a noise.  Earphones are a must; just listen away to the ipod and it’s good.   And if you need the bike, then a flick of the release handle and you’re back on the bike again.  Easy and really useful.

But how close is it to road speeds.  Well that’s hard to judge.  It’s also hard so say how far you’ve gone.  So I tried to move the CatEye Wireless to the rear wheel instead of the front wheel.  Problem there was that the receiver doesn’t pick up anything, which is a shame.  So, the solution was to get a wired computer from Bike Bug in North Sydney and some velcro dots.  I attached the wired computer to the frame of the trainer and the reader to the rear of the bike.  Once that was up I then had distance and speed measured (usual things to know for service etc).   The speed seems to suggest an average of 33KPH, which does make sense for nice flat roads.  Being able to keep this sustained is even better and should hopefully help in the long run.

All in all, I’m pretty happy with this and as long as I use it often, which is the key, it should work out quite well.

  1. Sounds like a good idea. Do you have any bike tracks near where you are?

  2. Not really up this way. It’s all road stuff here which isn’t great.
