Better than expensive competitors

This bottle cage has been the most robust and reliable which is why I purchased them for my family's bikes as well as mine. Quality is much better than the expensive competition.

Works as advertised

Make sure you have enough room to insert and remove the bottle. But it works well. Great if your limited on space.

Hello Geoff,

Thank you for taking the time to post your review.

Have a good day,


Too tight a fit for bottles

Bought this for a small frame road bike. The std bootle is a very,very tight fit; no doubt that a bottle would stay put. However I would not want to try and take out and put back a bottle whilst riding and cant stop every 20mins for a sip

No complaints!

Bought two for 4 day bikepacking trip around Cape Wrath. Nothing broke and nothing fell out even on bumpy tracks. Still going strong.

Ok but...

Got this for the trails but - for me - did not find the side access any improvement over the usual.

It's not for standard 74mm bottles

The cage is made of resin which seems tougher than usual company Z glass-reinforced nylon material. It can switch from RH release to LH release by repositioning the bottom tab which is a very clever design. I tested with Decathlon bike bottles in a store and it fits very nicely. However, at home, I tried to put my standard 74mm bike bottle it takes but tight so the bottle is in squeezed state which is certainly not very good for the bottle after a long term use. I don't know why this cage was made tighter than the standard bottles. Other than that I have confidence that the bottle won't come off on gravel and occasional off road rides.


Very good design to hold the water bottle of the same brand.

No screws are included

I just received the bottle cage but found that no screws are included (which does not mention in the product description). I don’t know where I could get these screws to fix the cage.

Hello Hon Man,

So sorry about hearing your unpleasant shopping experience,

please don't hesitate to come visit MK store or TKO store to grab the screw from our cycling sports leader.

Or you are welcome to visit any of our stores to exchange or refund in any of our stores.

Thank you for your support and wish to see you again soon.

Should you have any enquiries, please do not hesitate to contact us for further assistance.

Stay healthy.

Works as expected and serves the purpose

I am very happy with this purchase. Although, I have gone out cycling very few times after I bought this, it did come for good use and holds the bottle quite well.

Why choose a bottle cage with side access?

In some cases (full suspension mountain bikes, small frames, bikepacking with bags on the frame, etc.), getting your bottle out of the cage can be tricky. So this bottle cage lets you slide your bottle in from the side. What's more, it can be mounted in 2 different directions so you can choose whether to put your bottle in from the left or right.
