Perfect for between bike sizes

I ride the Triban 520 road bike but the only size available when I purcahsed was a large frame, this shorter stem works well to make the fit better for me (5'7"). No issues so far with the stem itself, the only thing I don't like is the bolts are silver and stand out against the black. The stem that came with the bike had black bolts.

Kinda ugly but perfectly good (and affordable!)

Small is beautiful

This short stem was used to give a more upright position than the 80mm stem - it does has expected and has made a massive difference! A cost effective and neat product !

Does the job

Cheap as chips and does the job well. If you are looking for a part to make your riding position more comfortable or as a cheap replacement, then this is fine. If you need a lightweight part for performance, then look elsewhere and be willing to pay ALOT more.

Needed a shorter stem and this did the job, same rise just 20mm shorter

icon-circle-checkmark verified purchase

Was looking to shorten my XC MTB stem to get more response from the steering and looked around for ages, then came across this while in the store for something else. Almost all AL6065 stems are the same, regardless of who makes them, so this being under a tenner is great. Unless you are in to downhill stuff and need a real beast of a stem this will do the job just fine. Only negative is the picture on the website is not quite right, the stem bolts are actually silver rather than black.

Bike stem purchase

The assistant was a Zwift specialist who saw my fit on the bike and suggested a shorter stem. They were all personable and took their time to make sure I was comfortable on the bike before I left. Very good service.

Amazing value stem

I bought this stem to replace the 80mm one that came on my Rockrider 540. The stem feels very sturdy and well-made, which still being fairly light. The stem i received looked a little different to that pictured, lacking the white Oxylane logo. Installing a relatively short stem like this is a great way to adjust the reach of your bike to improve riding position, and to make the bike feel more responsive. The only complaint I have is that my stem came with silver bolts, which stand out a little against the black finish of the stem. I would have preferred black bolts. Still, for the price one can't complain too much.


Amazing value for money. Very nicely made and finished. I have it on my 150mm full suspension bike and it is plenty strong enough. It's light too and the question is ....why pay more??

Good quality Oversized Stem.

I bought this to replace the cheap, 74mm Chinese branded stem fitted on my Hybrid bicycle. There is definitely an improvement in the riding posture, as I feel relatively relaxed now. This is a must-buy for those looking for shorter stem length.
