Only suitable for 36° bearings
The description of the item did not show that this item was only compatible with 36° bearings and not with 45° bearings.

I can't use it and you don't have any crown race reducer for 45° bearings.

CONS: Limited Compatibility

Good Product
I used this to fit my Rockshox Recon 1 1/8" to a new Niner Air 9 with tapered headtube. The reducer works as intended, and fits well. The only con I can mention is that it was difficult to set the reducer to the crown race.

PROS: Durable, Lightweight, Works As Intended

CONS: Difficult To Install

Works well
this allowed me to run my 1-1/8" steer tube domains in a 1-1/8-1.5" tapered headset. Been out for a few rides, seems to work well, with no issues. Way cheaper than a new headset, and most headsets that claim to be "reducers" seem to only provide one of these reducer races anyway... so to date a great product at a great price.

super handy
I used this to get a new fork that didn't have a tapered steerer tube to fit my tapered head tube on my diamondback mission. It only fits certain headsets so make sure of yours before you get it. For me it was a miracle cure that saved me from buying a very expensive headset. It has not flexed that I have noticed and i have already been jumping and dropping on it.

PROS: No need for a new headset

This was an upgrade to a new and better fork. The stems were different sizes so I needed an adapter to fit tapered stem

Pretty decent
Well all crown races are gonna feel difficult to install. Besides that, out of the box this thing feels pretty heavy, but it's also super durable and works great as a reducer.

PROS: Easy To Install, Attractive Design, Durable

CONS: Heavy

Can this be used for top and bottom headset reduction? My demo 7 has a 1.5 straight and I need to convert to 1 1/8 to run my fox 40
NickA on Mar 13, 2017
BEST ANSWER: It may be possible to use the reducer on top as well but I would advise against using this conversion for anything other than a short travel bike. It's not the strongest option. I would recommend a lower headset cup that reduces your head tube
Can I use this for dirt jumping?
A shopper on Jan 31, 2017
BEST ANSWER: Yes it will work fine on a dirt jumper.
