The FastTT Adjustable Angled Riser Kit (Extended) is a pair of CNC-machined aluminium risers that set your aero bar extensions at 15–30° and add 50 or 60 mm of forward reach and about 40 mm of stack. For twin-stack base bars with 24–38 mm bolt spacing (M5 or M6). Bolts for both included.
The FastTT Adjustable Angled Riser Kit (Extended) is a pair of CNC-machined aluminium riser blocks that tilt your aero bar extensions up anywhere from 15° to 30° and move them forward by 50 or 60 mm compared with FastTT’s standard angled riser. It bolts to the base bar’s mounting holes and adds about 40 mm of stack.
It is made for riders on a twin-stack set-up who want their extensions angled up and further forward than the base bar allows: triathletes logging long aero efforts on the Al Qudra cycle track and the Nad Al Sheba loops, and time triallists dialling in a position they can hold.
Check these four 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, 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.
- Quintana Roo V-PRi owners: Quintana Roo does not endorse fitting any accessory that extends reach on the V-PRi.

A note on forward reach
FastTT does not encourage extreme forward reach: it can put more stress on the bike’s mounting system than the frame and base bar were designed for. FastTT considers 60 mm enough for a comfortable set-up and generally advises against going further. It is up to the rider to make sure the set-up is safe and correctly fitted, so have it installed by a qualified mechanic.
What makes it work
50 or 60 mm more reach
The extended top block gives two forward positions, 50 mm or 60 mm further out than FastTT’s standard angled riser.
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, measured as FastTT’s nominal stack height.
Guide tracks and a wire channel
Machined guide tracks minimise sideways movement, and a shifter wire channel keeps the install neat.
Who it is for
- Triathletes and TT riders on twin-stack aero bars who want more angle and more reach
- Riders whose current position feels cramped with the extensions flat
- Fitters and riders fine-tuning a race position before a big event
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 (reach, angle range, stack, bolt spacing, threads, material and what is in the box) are listed in the Information tab.
FastTT does not publish the kit weight, its exact dimensions, 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 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.
How much extra reach does it give?
50 mm or 60 mm, compared with FastTT’s standard angled riser. It also adds about 40 mm of stack and lets you set the bar angle between 15° and 30°.
Can I add a reach extender on top for even more reach?
FastTT generally advises against going beyond 60 mm of forward reach, because extreme reach can overload the bike’s mounting system. Talk to us or your fitter before combining reach accessories.
I ride a Quintana Roo V-PRi. Can I fit it?
Quintana Roo does not endorse fitting any accessory that extends reach on the V-PRi. Please check with Quintana Roo, or ask us and we will help you find another option.
