GoHZQ 6 Pcs Headset Spacers 1 1/8", Aluminium Alloy Headset Spacers for Bikes, 28.6mm MTB Road Bike Stem Spacers 2mm/3mm/5mm/3x10mm Black

Fit perfectly to my Broadman ADV 8.6 bike. Feel strong and sturdy, look great, do the job.

Great product

I'd purchased a new adjustable stem for my electric bike as I was getting shoulder ache on longer rides. When I fitted the new stem, it soon became apparent that it wasn't as deep as the original and I had insufficient spacers to provide the 2-3mm clearance required to compress the stem set properly.These did the job perfectly. There are a good number of sizes provided which allows for selection of the perfect choice of combination to give the right clearance and they aren't under a huge amount of load, so they should last the lifetime of the bike.

They're a sturdy enough spacer given that they are being compressed so unlikely to fail. Aluminium alloy with decent black shiny finish they are good but... Prior to purchase I did'nt think about the outside diameter being anything other than the same on my Boardman road bike. As you can see in my photo, the spacer I was adding is smaller. Not a functional issue but if you are upset by the mismatch you are at least now informed. They measure outside diameter 34mm, inside diameter 28.7mm. As it happens, I didn't use in the end. My headset was loose and I thought an extra spacer was needed. In fact the top screw is threaded into a 'nut' down inside the fork tube. On my bike this is an expanding collet type fixing and it had come loose allowing it to get pulled up be the screw. I pushed it down, tightened it with it's own hex socket and all was good. No spacer needed at all!

This item fits perfectly and it has solved the problem of the space I had to fill having bought a new stem, I found the size I needed to raise the stem and it has made the job easier.

Seems good, I used them with some tipple clamps.

Value for money

Good selection of spacer widths, which enabled me to upgrade the headset on my grandsons mtb .
