Title: Deep aero rims (90mm+) / Tri Spoke / Disc Wheels for time trial bikes
Post by: TPR_Adventure on November 26, 2025, 07:23:34 PM

Hello everyone,

I have been a silent reader for some time now and am planning to build a complete TT bike for 2026.
I am currently looking for the right wheelset and unfortunately can only find options with a moderate width (mostly 28-29 mm wide).


1) Do you know of any rims that are between 90 and 120 mm deep and have an outer width of at least 31 mm?
1.1) I would also be interested in a full disc rear wheel with a DT hub and the same outer dimensions.

Most manufacturers usually only offer 28 mm wide rims/wheels, such as Lightcarbon here:

I would appreciate tips on individual rims as well as complete wheels.

Thank you for your feedback. I have found a few wheels here in Europe that fall into this category.

I was hoping to be able to purchase something similar as rim only. The only thing that comes close is the 80mm Rim from Carbon Bike Kits.

Here’s a listing on AliExpress with a 108mm deep / wide option, but rims only. However, the ‘product details’ suggests they will build complete wheels too if you reach out to them. The 80mm deep x 23mm ID rim looks good to me too…no clue about quality, though.

Btlos has a 106mm deep rim with 35mm max width:

I would personally go with something less deep as the gains are very marginal and in conditions where they can possibly give you a decent benefit is conditions you don't want to ride them in. Basically, trying to get something that is attached to your steering axis to act like a sail it not necessarily a good proposition. It looks cool, though.
