Used for a 90s Auburn 20in BMX bike. Works proper, nice and tight with original forks.

Worked PERFECTLY for my 03 Trek. For me it was fairly easy to install, and even without the relevant special tools, but just be aware that without said specialty tools (technically 3. A tool to remove "cups," a tool to press in the "cups," though can easily make your own with long bolt, wide washers, and a nut, and a tool for seating bearing race on fork), unless you're fairly mechanically inclined and have access to variety of tools, possibly enlist help or take to shop. And use grease/lube to aid in pressing if you do attempt yourself. Great product! GREAT VALUE! DEFINITELY RECOMMEND, if you have 1 1/8" steerer tube, non-tapered, and bearings of relevant size (can't remember the number at present). I wasn't 100% on my steering tube width. As it's older, I feared it was 1". But the bearing sizes matched mine, so went for it assuming my steer tube WAS 1 1/8" and yup, like I said, perfection!

Since I had a hard time finding a headset for the particular bike I was building, I chose the Full Speed Ahead kit because the dimensions, we're very close to I actually needed#. The end caps, had to be machined, to remove a slight amount of material, from the OD of the end that goes into the frame. This was a very slight inconvenience for me, however once I got the parts back from the machine shop, they went in perfectly! And they function perfectly! High quality headset from Full Speed Ahead. Quality merchandise at a reasonable price, I just wish there were more stickers with their logo in the Box!

Basic Headset This is super basic, I did like the over-sized bottom bearings and cup, but the top cup assembly was only so so. I didn't like the way that the wedge was kind of exposed. my almost 20 year old aheadset seemed to have a better design, and the cup and top cap still looked to be in good shape, so I used the new bearings, cleaned up the old cup and cap and reused the top half of the headset. I still give this 4 stars because the parts do look to be decent quality, and I needed new bottom bearings, and crown race. these parts alone would have cost more than the entire set from FSA. So, in short, if you are looking for something cheap that will do the trick, this will work. If you need only a few parts, this would be good for parts, but I think if you want a nice looking headset you may want to consider something that costs a little more..

Steel is real! I have a 1998 Gary Fisher Hoo Koo E Koo project bike. I originally purchased an FSA Orbit MX alloy/sealed bearing headset because it was lightweight and a good price (and it came in blue!). But, oh man did I have problems with that thing! It simply would not adjust properly. Long story short: lightweight alloy parts and sealed bearings aren't always the better product! So, I purchased this old school FSA Hammer to replace the alloy Orbit MX. Wow! What a difference! I had no issues whatsoever putting this headset on. The Hammer headset has beefy steel cups and a super durable steel lower fork crown race. I suspect my original problem was the flimsy alloy race that came with the Orbit MX headset. Problem solved and I'm happy. BTW, my headset did not come with the "Hammer" logo, just one "FSA" logo on the lower cup. No biggie.

Installed this on a mtn bike with front suspension. Install went fine and headset performs nice, but the description (under additional features) is incorrect to say this is a sealed unit.

Upgraded to a new front fork on my Hyper Explorer and replaced the Walmart grade headset with this FSA headset while I was at it. Definitely a nice headset and big upgrade from what was on there.
