The FastTT Twin Stack BTA Bracket lets you stack two bottle cages between your aero bars. It is CNC-machined, anodised aluminium and works best on FastTT’s Ultra Tall BTA Tower.
- Two bottles, up to 850 ml each
- Fits standard 65 mm bolt-centre mounts when raised
- Bracket only: bottles, cages and tower not included
Long-course racing and long summer sessions in the UAE often call for more fluid than one bottle between the arms can hold. The FastTT Twin Stack BTA Bracket lets you stack two bottle cages between your aero bars, so you can carry two bottles up front instead of one.
It is a CNC-machined, anodised aluminium bracket with pre-threaded holes for two cages. FastTT designed it to work best on its Ultra Tall BTA Tower, and it also fits any standard bottle mount with 65 mm bolt centres, as long as it is raised high enough. Useful for an Ironman build or a long ride out to the Al Qudra cycle track.
Check these before you order
- Bracket only: the kit contains one bracket. Bottles, cages, tower and adapter plate are not included.
- Height: on a standard 65 mm bottle mount it has to be raised high enough. FastTT recommends its Ultra Tall BTA Tower.
- Mono riser bikes: not suitable unless fitted with a FastTT adapter plate and the Ultra Tall BTA Tower.
- Bottles, not hydration systems: bottles up to 850 ml each. FastTT says it is not suitable for mounting hydration systems.

Fitting
FastTT does not publish fitting instructions or torque values for this bracket, so follow the torque figures from your tower or mount maker, and check the bolts again after the first ride. Our workshop can fit it with you.
All technical details (bottle capacity, mounting, compatibility, material, finish and what is in the box) are listed in the Information tab.
FastTT does not publish the bracket’s dimensions, bolt sizes, torque values or product weight, so they are not listed here. The weight in the Information tab is the value we use for shipping.
FAQ
Will it fit my bike?
It fits a standard bottle mount with 65 mm bolt centres when it is raised high enough, and works best on FastTT’s Ultra Tall BTA Tower. On mono riser bikes it needs a FastTT adapter plate and the Ultra Tall BTA Tower. Send us a photo of your cockpit if you are unsure.
What is in the box?
One bracket. Bottles, cages, tower and adapter plate are not included.
How big can the bottles be?
FastTT approves bottles up to 850 ml each.
Can I mount a hydration system on it?
No. FastTT says it is not suitable for mounting hydration systems. It is made for two bottles in cages.
Is it legal for racing?
FastTT does not make a race-rules claim for this bracket. Rules on where bottles can sit differ between race organisers, so check your race’s equipment rules before race day.

Bikeera stocks the Fast TT UAE range of aerobar accessories for triathlon and time trial cyclists. Fast TT is a brand that makes quality parts for fitting, adjusting, and upgrading aerobars on tri and TT bikes. The range also covers riser kits, BTA bottle mounts, stack kits, elbow pads, and bolts.
Adjustable Angled Riser Kits let cyclists dial in their arm position for comfort and speed. Tall Stack Kits in 140mm and 190mm heights raise the arm pads to suit different rider fits.
