Very impressed with the construction; very study, yet lightweight. All of the other rear WB cage mounts I've used before wiggle, sag, break, snap bolts, etc. Very well-engineered!
Good: I didn't feel noticeable faster but I don't doubt my bike is slightly faster. The disc wheel is quieter when compared to some disc that make that womp womp sound.
Not so good: The disc shifts position slightly, even with all the tape and zip ties. The shift in position and the valve stem openings distance from the edge makes putting air or sealant in a tire difficult. You will most likely need longer stems and an air chuck adapter.
Bad: Don't use in the rain or leave bike uncovered in the rain (hard to do at a race). Water gets into the rim/disc (via center holes) and takes awhile to drain out and can cause imbalance.
Finally, if you live in the US you will be billed a 20% tariff Politics aside, EZgains should provide this information in advance and let the consumer decide. The current statement says some import fees may be charged. Had I known I would have NOT ordered this disc wheel.
wasn't clear that they were already included with the hydration system - too much hassle to return so they are in the junk drawer!
la pestaña no se ajustaba a las medidas del asiento y como consecuencia no entraba en su totalidad para poder anclarla 100%
Was supposed to be free shipping and then charged me $60
I was sceptical as it is quite an expensive BTS System, but I was super impressed with the fit on my Fitzik Saddle. It is extremely well engineered and definitely worth the money.
Really impressed with this. I originally tried a cheaper 3D-printed alternative, but it broke after just one ride, so I decided to go for the EZ Gains setup instead.
The difference in quality is obvious straight away. It feels much more solid and secure, fits my Selle Italia Watt saddle properly, and held the bottles firmly even over rough roads during training and racing. The whole setup is also very neat and aero compared with a conventional rear hydration system.
It’s not the cheapest option, but after trying the cheaper route first, I’d say it’s worth paying for something that you can actually trust in a race. Really happy with it.
- just put a simple bite-on mouth piece on the tube
- hairband to tug the tube to the canister
- some string or similar for the plug to pull it out more easily while riding to top up tank from bottles
Pretty heavy and expensive for what it is
Great quality item - Cervelo P5 mounting bracket. Will definitely use again

Thank you for your feedback. We are pleased to hear that you were happy with the products.
For clarity, three separate reviews have been left—one for each item—but all three items were purchased and shipped together as a single order. Therefore, the customs bill related to the complete order, not to each individual item.
The “customs charges not paid in advance” option was selected at checkout. This means any import VAT, customs duties and FedEx clearance fees are payable by the recipient upon arrival. These charges are set by the destination country’s customs authorities and are required by law; unfortunately, EZ Gains has no control over either their application or the amount charged.

Really impressed with the specific fit to my Selle Italia Watt Superflow, its perfect. I went from a cheaper double bottle mount which failed over time with two 750ml bottles to the EZ Gains Hydro Mount and I'm really impressed with the quality and how sturdy it is. Also a lot easier to access/stow the bottles whilst on the move compared to the cheaper option which was under the saddle, awkward to access and fiddly. Another premium product from EZ Gains!
Contributed to my sub 5hour 70.3 and im sure it’ll aid my goals of sub 10 hour full IM!!
Great product
To be honest: This stuff is the best thing from England since winning World War 2. Yes, it's expensive. And because of the f...in Brexit I had to pay more than 100 € for tax. But: It was worth every cent. So thank you very much for engineering finest Bike-Stuff. And, of course, also thanks for 8 May 1945: The day of victory over the Nazi dictatorship. Looking forward for the next shopping at your store. Kind regards from Herford, Christian
I’m not super happy. It flexes a ton and that’s only by me moving it. Please reach out to me.
