Stack and reach
How high and how far forward the top of the head tube is, from the bottom bracket. They are the two numbers that decide whether a frame can be set up like yours.
BB, or bottom bracket
The axle your cranks turn on, in the middle of the frame. Every number on this site is measured from it, because it is the one point that sits in the same place on every bike.
Headset cover
The little cap on top of the head tube, under your spacers. Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.
Stem clamp, and its centre
The collar on the steerer that your stem bolts to. I need the middle of it. Where a maker gives only the height, I assume halfway up and say so on the answer.
Steerer
The tube coming up out of the fork. The cover, the spacers and the stem all sit on it, and it is the thing a mechanic cuts to length.
Bar reach
How far forward the hoods sit from the middle of the bar. Two bars on the same stem can put your hands 20 mm apart, which is why I ask.
Setback
How far your saddle sits behind the bottom bracket.
Drop
How much lower your hands sit than your saddle. On a riser bar I count the bar's rise, so the drop is that much less than it is to the clamp.
Rails, and the rail centre
The two rods under your saddle, and the middle of the straight part of them. That midpoint is the point I use, because it is the one you can find with a tape.
The band
How far out I could be, in millimetres, and why. It is a straight sum of everything I had to assume rather than a clever average, so it errs wide on purpose.
wb, stand, trail
Wheelbase, standover and trail: how long the bike is, how high the top tube is where you straddle it, and how steady the steering feels. I show them against your bike, and I leave them out when the maker does not publish them.
est.
Estimated: a number I worked out rather than read off the maker's table. Anything marked this way can move if the maker publishes the real one.

Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The S drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm.
The maker's cockpit
No stock cockpit I can name, so every size is solved on a generic stem and bar unless you choose one on the sheet.Generic stem and barAssumedNo bar is listed for this frame.

How I read the maker's table
both carry the same A9, A23 and TRA01 frames under the ICAN name, and the frame below is on icanbikes.com only (not in icancycling.com's product sitemap, fetched 22 Oct 2026). The page "Lightweight Carbon TT Bike | Carbon Fiber Tri Bike | ICAN Bikes" sells the TT017 as a complete Shimano Dura-Ace Di2 bike (8.8 kg) and the frame by its geometry image (uploaded Jun 2024; Bike Insights files it as ICAN TT 2025, build 017; no model year printed, model_year null). Columns as printed, XXS/XS/S/M/L: S seat tube, SC seat angle 75 every size, O top tube (drawn horizontal from the seat tube line to the head tube top: top_tube_effective), HS head tube, HC head angle, F fork length 365 (not in the schema), OT fork offset 45, WB, FC front centre, RC chainstay 410, G BB drop 75, Reach, Stack (to the head tube top, below the integrated bar mount). No trail or standover printed. The stack steps are small at the top (495, 497, 503 for S, M, L) while reach grows 15 mm a size: as printed, and each size closes its own top tube within 1 mm. Spec table: Torday (sic) T700/T800, sizes XXS/XS/S/M/L, T47 68+/-0.5mm, UDH, internal routing, front 160 and rear 140 mm rotors.
