Rubber dumbbells vs cast iron dumbbells

I'm not interested in which is more aesthetically pleasing just which is the must robust and long lasting product?
 
I'm a little sceptical of the rubber for a few reasons. From what I have learnt the rubber ones are bigger relative to the cast iron bells. Has anyone found this a problem?
 
They will also take up more space. My rubber floor is ok in the cold garage so the bells would probably be ok but are they as robust? Is it new age poorly built equipment?  
 
Looks like everything is rubber apart light bells. Only cast bells I see north of 30kg are these but they need to be assembled and tightened with an Allen keg. I wanted bells which are all one fixed unit.

Those training in a gym with the rubber dbs I would appreciate any help
 
This guy doesn't like the rubber

As mentioned in another thread, prefer cast iron with convex grip. You might think im being picky with the grip, but to me, makes a difference. Even subtle differences when lifting heavy help prevent injury, wear and tear.
 
Any weight should last forever provided they looked after, I get fed up with folk who drop dumbbells when finishing off their lift, this is what breaks them. I will say that there are a few plastic ones down at the gym showing signs of wear, cracks etc.
 
Plastic ones are larger, for me this is an issue.

The two issues I have with rubber dumbbells are that they a lot more cumbersome as they are bigger for a given weight and the rubber catches on clothing during reps more than iron does.

However these issues are minor compared to my main factor in whether I like a Dumbbell which comes down to the handle e.g. conxex or straight, good knurling, thickness, free rotating...

Also the flatness of the ends is important when resting on thighs. It much more comfortable with flat ends than when there is a protruding bolt.

So many variables and when I am going £1500 - £2000 it has to be right.
I recived an email back from powerhouse fitness with photos comparing the rubber bodymax pro 2 and v4
The v4 are wide, the pro 2 look longer. I need more photos over head. Yet reviews say compact bells for v4.
Thanks for helping me out guys I really appreciate any help here
What would happen if the dumbbell isn't free rotating? A fix iron bells would be rotating would it? I know my Olympic ajyatable hangles are rotating. Are mostbells in gyms free rotating.

I like rubber if you have good floor mats ( really good floor mats) and you have decent people using them , Cast Iron usualy need alot more welding and rust in your eyes , rubber do wear and have bits falling off them .  they would definaltey need a rotating handle , that for me is the most important bit.
 
Rubber you also get a decent bounce when benching or flying , cast iron are a lot more forgiving , but that probably depends on the person.
 
It would probably come down to price , if it was plates they would deffo be cast iron, way too many people drop and break rubber plates

Thanks doc really appreciate the help mate. Have you found the rubber bells to cumbersome?
What would you get? No price concern. Must be right and the best choice.
I would have thought people would drop bells more than plates?
I have Jordan rubber floor mats half inch thick, seem good to me, are the rubber bells more likely to break?
What would happen with no rotating handle?
Cast iron still seem the safest choice, can't see than over 30kg. Looks like them York bells legacy would not have rotating handles, looks like all on single unit.

I have found some rubber dumbells cumbersome , if they are too wide they dont make for a good dumbell press and you cant get a good squeeze at the top , the Jordan ones seem pretty good , for shrugs they are a pain in the arse as they are just too big as you need 60-70 kg so easier to use a machine , if they arent as wide and 'higher' they can be cumbersome for one arm rows but other than those exercises id probably pick rubber over iron , so maybe 5-45kg rubber , anything bigger id go cast iron.
 
No rotating handle and I woudnt buy them , would also need quite a thin bar aswell, nothing worse than having a knob sized bar to grab hold off and they are hard to handle without straps even if your doing chest and just getting them up, the grip would also need to be non course , ive had some that litteraly take the skin of my hands.

Doc and others
 
Have you used a fixed non rotating handle db before?
 
The main benefit from a rotating handle is wrist protection and so you don't have to rotate the bell yourself when lifting from the floor to over head. From watching this video I also agree its essential. I want old school bells just like this!!!!
 
 
 
If the bar is thin your wrists will fall back if you have big hands when pressing, which means the line of force wouldn't be in line with your humerus bone. I would like a dumbbells bar the same thinness as an oly bar which is the same as my adjustable oly handles.
 
This is email back from powerhosue
 
left is a 6kg v4
 
right is a 5kg pro 2

Ive got a set of bowflex adjustable ones. they are decent to be fair, I wouldn't drop them and they are a bit long with smaller weight on, id suggest a set of adjustable ones up to 30kg or something, then get some fixed above this weight.

from looking though you wouldn't know if they rotate, says Aircraft-grade hex bolts help prevent loosening. fcuk knows i'll ask them. I'm done for now.

Thanks for the input. However I'm set on a rack and dumbbells. When warming up there would still be some weight change though 15kg then 25kg before moving to the pro bells for another low rep warm up or two. Must be a rack.

If I could afford them and had space I'd get a set of these...
http://www.ivankobarbell.com/products/rmep_15/
I used to belong to a gym that had two sets... The iron ones in lbs and the the rubber coated ones in kg.

yeah ive used none rotating bars before , if they are 10kg they are fine, but when you start getting heavier it natrualy wants to turn and to do that you need to relax your grip , which is difficult when flying as everything is under tension , not a fan at all , those dumbells look pretty good to me, like I said for me persoanlly 40kg and below and the rubber dont seem too cumbersome , 45+ and they start getting too wide or thick . dumbell should pressing the 60kg's with rubber was almost impossible as they where hitting my ears or pulling themselves away from my body , very hard to balance , those dumbells in the vid are excellent if you dont have people dropping them , they need lots of welding tacks and ussualy have bit dropping off in your eyes when chest pressing . 
 
as a rue of thumb for me if i can roll a dumbell along the floor as ster it left/rigth without having to pick it up , then its got enough good rotation to use , if i have to pick it up to change its direction to avoid a plate or bench then ill just use a different weight

I've made my mind up I don't want rubber I want cast iron so that one box ticked.
 
Sean
Great shout, they look perfect its collection though. I wouldn't want the 5kg and 10kg and probably add 45kg though. Another ad on ebay on your linked show rubber dbs but in plates, like iron bells are. That looked better and slimmer, I don't like the big block rubber.
 
Furious D
 
Its ivanko though, I think their just a bit to much money.
 
Doc
 
Yes I need rotation in whatever bells. I disagree with you on a thin handle though. Big hands will bend back. In fact the fat grip rubber things are a good thing for big hands when pressing, wouldn't use they when rowing though.
 
I think its down to these
 
Doc and others if you can have a quick look these, what do you think to them?
 
body power pro style dumbbells
 
https://search.fitness-superstore.co.uk/search?p=Q&srid=S4-2LON2P&lbc=fitness-superstore&ts=custom&w=Body%20Power%20Pro-style%20Dumbbells&uid=637858407&method=and&isort=score&view=grid&srt=0
 
Not a bad word said about them
 
However it says
 
Pro-Style Dumbbells are supplied un-assembled and require an 8mm Allen key to assemble
 
Dumbbell weight does NOT include the weight of the handle; Pro Style Dumbbells must be checked & re-tightened where necessary after use
 
I didn't think they would be the safest, but a reviewer said
 
They come with a very long thread that you have to use an Allen key to unscrew, therefore they don't become loose
at all whilst lifting.
 
 
Other option is this, but some of the bells are out of stock 
 
https://www.jordanfitness.com/collections/dumbbells-use/products/jordan-cast-dumbbells?variant=830948881
 
 
Very importantly which ever I choose I need to know the handle thickness and if they rotate.

I have both types and both are equally fine.  Although I prefer the rubber ones because with the other type that I have which includes allen key and spinlock, the latter requires constant tightening as it keeps loosening up.
