The FastTT Adjustable Angled Riser Kit M5 (Standard) is a pair of CNC-machined aluminium risers that set your aero bar extensions at 15–30° and add about 40 mm of stack. For twin-stack base bars with 24–38 mm bolt spacing (M5 or M6). M5 top threads for FastTT aero bars; bolts included.
The FastTT Adjustable Angled Riser Kit M5 (Standard) is a pair of CNC-machined aluminium riser blocks that tilt your aero bar extensions up anywhere from 15° to 30°. They bolt to the base bar’s mounting holes, add about 40 mm of stack, and take FastTT aero bars directly on their M5-threaded top blocks.
Angling the extensions raises your hands without changing the base bar. It is made for triathletes and time triallists on twin-stack set-ups dialling in a position they can hold for long aero efforts, whether that is laps of the Al Qudra cycle track or the flat, fast Nad Al Sheba loops.
Check these three things before you order
- Twin stack only. This is not a mono riser adapter.
- Base bar bolt spacing 24 to 38 mm (hole-to-hole centres), with M5 or M6 bolts. Bolts for both are in the kit.
- Your aero bars: the top block has M5 threads (holes 36 mm apart), made for FastTT aero bars. Other brands need FastTT’s Angled Riser to ‘Other Brand’ Adapter, which is sold separately. Ask us before you order.

What makes it work
15° to 30° bar angle
Set the extensions anywhere between 15° and 30°, using the angle scale on the side of each riser.
About 40 mm of stack
Each riser adds roughly 40 mm of height under the extensions, FastTT’s nominal stack height.
Machined guide tracks
The top and bottom blocks lock together on machined guide tracks that minimise sideways movement.
Shifter wire channel
A channel at the rear keeps the shifter wire tidy. Shown on spacers, which are not included.
Who it is for
- Triathletes and TT riders on twin-stack base bars who want their extensions angled up
- Riders with FastTT aero bars, which bolt straight onto the M5 top blocks
- Riders fitting FastTT’s Pro-X1 mono bar to a Cervelo P5: FastTT says this kit is required for that set-up
Fitting
Each kit includes both risers (left and right) and two sets of bolts: four M5×16 cap screws with washers and nuts, and four M6×16 cap screws with nuts, to match your base bar. FastTT does not publish torque values for the kit, so follow the torque figures from your base bar and aero bar makers, and check the bolts again after the first ride. Our workshop can fit it and set the angle with you.
All technical details (angle range, stack, bolt spacing, threads, block size, material and what is in the box) are listed in the Information tab.
FastTT does not publish the kit weight, torque values or colour options, so they are not listed here.
FAQ
Will it fit my bike?
It fits twin-stack aero bar set-ups where the base bar mounting holes are 24 to 38 mm apart (hole-to-hole centres), with M5 or M6 bolts. It is not a mono riser adapter, so it will not fit a single-post mono riser.
Does it work with my aero bars?
The top block has M5 threads, 36 mm apart, and is made for FastTT aero bars. To fit another brand’s bars, FastTT’s Angled Riser to ‘Other Brand’ Adapter is required. Ask us and we will check your bars.
Standard or Extended?
This Standard kit sets the angle and adds stack without moving the bars forward. FastTT’s Extended kit has the same 15° to 30° adjustment and 40 mm stack, and adds 50 or 60 mm of forward reach. Ask us which suits your position.
Do I need it for a FastTT Pro-X1 on a Cervelo P5?
Yes. FastTT says this Adjustable Angled Riser kit is required when fitting the Pro-X1 mono bar to a Cervelo P5.
Are spacers included?
No. The kit includes the two risers and the M5 and M6 bolts. One of FastTT’s photos shows the riser on spacers, which are sold separately.

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. For on-bike drinks, BTA brackets and tower spacers mount a bottle behind the arms. The Extended Adjustable Riser Kit also gives extra reach for longer arm positions.
Fast TT also stocks replacement elbow pads, mounting spacers, and M5 bolt packs for complete aerobar builds. FWD extender brackets add forward reach for the arm pad setup. Find the full Fast TT UAE range at Bikeera Dubai, with free delivery across the UAE on orders over AED 150.
