Question: Would this double as a maintenance stand? I'm guessing not since it does not clamp down...
Document: I've had no problem with the road bike (which I keep on top since it's lighter), but the mountain bike wheel tends to turn sideways and get in the way as I'm walking by. I've got the unit close enough to the wall that the handlebar touches slightly, and that mostly keeps it in place. But seems like the stabilizer would be worth it.My only complaint was with shipping.
Since then the clamp failed again once, but the cables stopped the rack from dumping the bikes onto the floor or our cars.I also asked my local bike shop about this, as they use these to display bikes. They have had the same problem where the stand lets go and crashes to the floor.
I'm not giving this 5 stars because the first time I received the stand it was beat to hell and had obviously been opened before by someone else. Since it is sold and shipped right from Amazon a 1-star deduction seems appropriate.All in all this stand works. I keeps my bikes up and out of the way and if you install it correctly and take an extra measure of security by installing a safety tether up top you should never have an issue with this falling.
It's been dutifully holding my bike ever since.It's reasonably stylish and, with my bike, it looks more like a piece of decor than a bike rack in my living room. Overall, I'm a very satisfied customer.
I'm sure all of this was easier for me since my place had fairly thick carpet, its probably a bit trickier on a floor surface without carpet. With carpet, I can grab the pole with my bikes on it and pull/push it, the whole thing bows slightly (not much) but holds its turf. No doubt my bikes will survive quite an earthquake.
Was concerned I would have to get rid of my two bikes. A friend recommended Topeak and I was able to buy it on Amazon at about $30-$40 less than at the local bike store. I'm keeping my bikes, it doesn't take up very much space and it is sturdy. Good product.
I was a little reluctant to buy this because several reviewers here and on the web said that they had trouble with it on hardwood floors - that it would slip and had trouble keeping tension. I also wasn't sure about the price in relation to the quality since this is two to four times more than other bike racks on Amazon. In the end, having owned other Topeak products which were of very high quality (seatpost bike rack, multi tool, etc.
I ordered this product so I could store my new road bike in my 1 bedroom apt after my old bike was stolen from my building's storage area. I wanted something that would get my bike off the floor with minimal damage to my walls, since I rent. This does the trick.It arrived mostly assembled. Once I found  the studs in my ceiling, set up was quick and reassuring.
So I'd lower the height, but then the tension didn't seem right. Or the pole would slip out of alignment as I tried to adjust it, making it crooked. After many attempts (and feeling a bit like Goldilocks), I got it just right.Other than that, I'm very happy with my purchase and still feel like I got the best storage rack that's out there.Update September 2010:  Indeed, this rack did fall over on to my husband's car with the bikes on it.
This stand is an excellent value especially considering the free shipping from Amazon. I was surprised and impressed by the high quality of the fittings and hardware on this stand.To avoid any damage to the ceiling should I happen to install in an unsupported area, I took a piece of scrap hardwood of about 18" x 12" and used it as a pad for the top support to press against.The people who had a problem with the stand falling over probably did not have the quick-release clamp tightened sufficiently.
Answer: no
