Review: Handlebar weight - Incredible weights. I've had them since July 2025. Just so you're all aware, the bar and spin lock weight is 1.6kg (without weights). Just something to bear in mind :)
Review: Great set of weights for any serious beginner. - Needed to do something about the belly and 'love-handles' that appeared over the past 2 years of lockdown! Was thinking of joining a local gym but... you know how that goes. So, decided to invest in these and build up towards my home gym. They were delivered in sturdy cardboard box which can be used to store them when not in use. But, for me, these will always be out on the floor. Otherwise, out of site, out of mind! I've had concrete-filled, plastic ones before but this time wanted cast iron ones which hopefully won't go rusty over time. The bars are chrome plated whilst the weights are finished in a hammered effect, dark-grey paint. Looks professionally finished and of high quality. Other reviewers commented that the screw-locks loosen during use, but I haven't had that problem. Really like the extension tube which converts the two dumbbells into one barbell. Not sure if I would trust loading the full 20kg with the extension bar, though. As well as bent-over-rows, bench presses and fore-arm curls it's possible to place the bar-bell on the floor, slip your toes under it and knock out a few sit-ups. The different weights are ideal for a beginner. Even the hand-bars alone, without any discs, are a good way to start, adding weights as you progress. I've used these daily for the past week and was ready to buy another set. There's always a 'however'. However, the price went up by £10 right after I got my first set. So, just waiting for the price to drop, or until I find another seller with a similar product and better offer. I will be buying another set, a folding bench, and a Straight / EZ Curl bar-bell, all available from the same manufacturer.

## Features

- Anti-loose rubber ring on the collar
- Knurled all-steel handle for grip and safety

### ⭐⭐⭐⭐ Good starter set
*by T***Y on 15 November 2024*

Brought for my son , the weights are solid and appear well made , good for starting out and enables him to cover lots of different exercises , the only reason this is a four star and not a five star is the extension to make a barbell , just doesn't seem long enough or feel right , as dumbbells these are solid and quality at a decent price range .
