Question: How thick are the handles.. can we make them thicker if they are not Olympic size handles thick 2 inch?
Document: These are perfect for circuit training and drop sets. They look like dumbbells from the future which I love.Ironmasters :The best build quality, size, durability, balance and distribution of weight of any adjustable dumbbells. The grip better than powerblock elites, in fact these are the best feeling dumbbells I've ever held.I actually dropped these a couple of times when doing a heavy set of chest presses on 3/8 inch thick rubber flooring and wow these thing can take abuse. They are absolutly tough! It does takes significantly longer to change weight with a lot of effort which powerblocks kills it in that category.
The outsides are squared in design with a notch on one of the sides of the square. The weights use a locking screw mechanism and made of steel as well. The handles are easily marked with an "OPEN" and "LOCK" to make it easy for you to know which direction you need to turn to lock the weights in place. The weights are also solid and made of iron, which in comparison to other brands that are sometimes plastic or cheaper materials. The locking screws make it easy to change in and out the weights within a matter of seconds.
These dumbells lock up as tight as solid gym DBs, so they can be used safely and quietly for  explosive work like full-body swings. They have  perfectly proportioned handles that comfortably accommodate one and two-handed work, and compact square plates that are heavier than they look. Asymetrical loading for leverage work is  easy and stable. The wide, flat inner permanent collars and big, flat-head, quick-lock pins make them comfortable in many positions not possible with other models: Horizontally and vertically, they're stable on the floor, and the ends can be held with palms up, between feet, knees, thighs for a great variety of  movements.
A quick cost analysis (per dumbell):Ironmaster  75lb at $224.5 = $3 per pound (increments in 2.5lb) includes pedestal stand, expandable to 125lbTurbobells 60lb at $150 = $2.5 per pound (increments in 2.5lb) includes tripodlike stand, not expandableBowflex 52.5lb at $189.5 = $3.6 per pound (increments in 5lb) includes weight tray, not expandablePowerblock 60lb at $184.5 = $3.1 per pound  (increments in 5lb) No stand, not expandableVersaBell 50lb at $131.5 = $2.63 per pound (increments in 10lb) includes weight tray, not expandableOne major advantage of Ironmaster is that it has 1-inch holes which will fit standard 1-inch threaded weight bars including the spin-lock ez-curl bars.
Instead of using dumbbells that weigh 45, 40, 35, 30 lbs, etc., use dumbbells that weigh 47.5, 42.5, 37.5, etc. Make each dumbbell so that 1 side has an extra 2.5-lb plate on the inside followed by 5-lb plates. For example, a 47.5-lb dumbbell would have 10 lbs for the handle and screws, one 2.5-lb plate close to the middle on one side of the dumbbell, 3 more 5-lb plates on that side, and 4 more 5-lb plates on the other side (this shifts the center of balance so little you won't even notice it).
I did a lot of research for an adjustable set of dumbbells. What made me decide upon the Iron Master set is the quality (having no plastic), the gym feel of the handles, the flexibility with the choice of weight (able to do 2.5lb changes), and the locking system (the sense of security that the weights were not going to fall off during workouts). I wasn't sure on how easy it would be to change the weights, but it really is as easy as described. I didn't know it at the time, but Iron Master will also sell the handles and locks separately.
By luck I happened to stumble across the Ironmasters on the web. I started looking at reviews and was amazed by the great things people had to say. After a little bit more research I decided I definitely wanted the Ironmasters.These are traditional dumbbells. They feel perfect. The handles and the screws are made of solid steel. The plates are made of Iron. The stand is steel. Yes it's not as fast to change the weights on the these compared to the other 2 but it's a hell of a lot faster than my old spinlocks and I have absolutely no worries about anything breaking.
When you're spending this much money, you really should get something that'll last forever. The bowflex may be quicker to change but the demos I tried in the store were very tricky coz the damn dials wouldn't budge. In front of my eyes the store actually replaced one of the 1090s as the display one had broken!! Anyways, back to the Ironmasters. They take up very little space compared to the Bowflex stand with dumbbells. The handles alone weigh 5lbs, the screws weigh 2.5lbs each and you get (4) 2.5lb plates and (24) 5lb plates.
When doing chest and military dumbbell presses I was always concerned they would fall on my head. They never did but it often affected my concentration during the lifts. The rattling of the weights doesn't ease one's concern. Finally, they did start to fall from the holder when lifting from the stand- tabs broken. Subsequently, the dials started to lock up on one of the handles.I bring this up because I considered buying the version 2 Bowflex Selecttechs but because of the above concerns about reliability, lack of longevity, and the constant concern that the weights would come loose, I decided against giving Bowflex more of my business.
I'll keep it simple here.1) NO, they are not "quick change" but if it bothers you so much, order another set of handles and load up two sets of DB's to alternate as needed.2) YES, they are the most solid of the major brands out there. I demo'd PowerBlocks and they just felt weird, and the Bowflex/Nautilus stuff will get destroyed in no time. Check out all the plastic parts i them and you'll know why. Plus they rattle, while the IM's do not rattle at all so long as you tighten them up.3) I keep a few rubber hex sets in smaller weights around just to avoid the changeout routine and keep these heavier.
Answer: yes
