i was under the impression that external width of rear TT disc wheels isn't as important compared to width of spoked wheels on the front. if you look at some of the leading brands (enve, aerocoach) you will see most of them at 28mm external. because the wind doesn't have to transition over the rim profile, it just moves along the surface of the disc, width isn't as important on the rear disc.

Hello, I am new to the forum and interested in this frame as I really like a mono riser and it's the only one I can find in size 58.

Can I get some help with 2 questions:

1. Are there any other options that are mono riser and size 58 that I should consider?

2. I have read through this thread and it appears the winow cockpit does not fit without adaptations?? I am moderately handy with bikes (I can build my own). Are the adjustments required to get the winow extensions on something a home mechanic can do?

Thank you

i can't speak to your first question, but for question 2, the winow arb02 is a direct fit onto the supplied adaptor plate. Its not entirely clean or pretty (the circular carbon extension mounts poke out a bit, unless you want to cut them off). i purchased this adaptor plate and drilled out the hole spacing so it would match the mono riser bolt spacing for a slightly cleaner look:

Nice setup.  I've ordered the same color as well.  The TR:ONE COCKPIT is available to buy separately now.  Just wanted to confirm that it will fit the ICAN TT017 before purchasing.

Where did you find that base plate on AliX?  What new plate are you getting?  Any chance of linking the item?

Cheers

no probs, the adaptor plate in this listing is what you want to get

the only reason i got a second adaptor plate is so i can move my aero extensions out a bit further. if you get the correct length extensions there is no need to order that one (it actually doesn't fit the mono riser at all, i cut it in two and bolted to the plate above).

if you have a local carbon repair specialist (or even your LBS) take it to them and get an opinion.

someone has managed to get their hands on a fully wireless EGR and reviewed it

the largest cog it can accept on the rear is 46t, which is a deal breaker IMO

edit: these are the aliexpress listings for the new EGR, both say they can take 50t cassette

Thanks for the tip @pandaGravel15. I did not know of these Kairos extensions, but I've had good experiences with Tideace in the past. However, I think that the Kairos is probably not good for my needs as I don't think it's UCI legal in the larger sizes. The Vision Metron TFE Evo, which the Kairos is largely a copy of, has an angle of 15 degrees for the main extension and then 50 degrees for the ski part. The Kairos is a whopping 25 degrees plus 53 degrees for the ski! Based on my calculations, the height of the extension tips would probably be well past the UCI legal 14cm from the middle of the elbow rests.

i am jealous that you are in uci height category 3 and have got 14cm to play with for the aero extension rise. I was in the market for some aero extensions for my TT:ONE i had a look at the TRONE cockpit and the rise looks to be greater than the 12cm i am allowed in my UCI height category (even with 0 degree angle washers). And for that matter, most of the wattshop/fast TT copies on Ali look to cater for the triathlon crowd, since most look to be greater than 14cm rise. In any case I don't want to spend $600+ so also looked at aliexpress for cheaper options. I ended up ordering these last week in size small to (hopefully) sit within the 830mm limit from centre of BB to tip of extensions:
https://www.aliexpress.com/item/1005011547602630.html?spm=a2g0o.order_list.order_list_main.25.5c611802Dn8qvY

and the rise doesn't look to be too great, so (again hopefully) i can adjust so for around a 12cm rise from armrest to tip.

Also ordered this adaptor plate, the seller told me it should fit the monoriser on my TT:ONE, if not will drill out correct hole spacing.

As per above post I managed to source the correct BB and now have completely built up my TT017 and given a few good test rides. Specs are as follows:
•   Size large TT017
•   Groupset: Ltwoo ERX TT
•   Brake calipers: Wheeltop (supplied Ltwoo were problematic – see below)
•   Rotors: dura ace (160/140mm F/R)
•   Saddle: Adamo copy
•   Chain: 12 speed dura ace (waxed)
•   Cassette: Sunshine 12 speed 11-34
•   Front chainring: 56t narrow wide
•   Power meter: Xcadey
•   Pedals: dura ace SPD-SL
•   Cranks: Rocks bros DUB 165mm
•   BB: Senicx T47 DUB ceramic external bearings
•   Rear wheel: Elite Velo disc (TPU tube)
•   Front wheel: Cannondale Hollowgram Knot 64 (tubeless)
•   Tires: Continental GP5000 S-TR (25/30c F/R).
•   Weight: 9.3kg.

Observations/notes
•   Fittings like bottle cage bolt and front mech hanger are branded Quickpro. Am guessing ICAN manufacture the TT One for Quickpro using a higher modulus carbon.
•   Since it came from the same factory, I purchased Quickpro decals just so I can flex on this bike with my friends. Much like Cannondale hi-mod frames, in my mind this is just a lower modulus TT One.
•   Paint quality was great, can’t see any imperfections with my eyes.
•   Ltwoo battery could not fit in seatpost or downtube, so I wrapped it in thin foam and wedged it down seat tube – it doesn’t rattle but will be fun to get out.
•   Cutting steerer tube to correct length was tricky. I erred on the side of caution and ended up cutting it one or two milometers too long (only realised after routing cables through). As a result it now pushes the plastic cover up so that its not flush with top tube (not a big deal). Think someone else in thread also mentioned this but would advise anyone ordering this frame to ask ICAN to cut it to correct length.
•   BB installation was problematic. I have a T47 16 notch 52mm tool however with the external bearings it was too shallow to fit over the bearings and reach the BB notches. Had to take to LBS who charged me $AUD65 for a 5 minutes job . Have now ordered correct tool off aliexpress for like $10.
•   It is heavy at 9.3kg but am not planning to do any hilly TTs. If I take out disc rear (that weighs 1200 grams) and use spoked carbon rear wheel I can get weight down significantly.
•   First time using Ltwoo electronic and am quite impressed. Bit of a learning curve to set up but the app (and shift indexing) is way easier to use than Wheeltop. I have noted elsewhere on Chinertown water ingress issues so I will put heat shrink over rear mech connector. Shifting speed is great, probably not as fast or accurate as 12 speed Di2, maybe down the line I will put a Ultegra 11-34 cassette on it and that will make shifting even better.
•   Ltwoo brake caliper with 160mm adaptor would not fit in front fork recessed brake mount. Replaced with spare wheeltop caliper.
•   Rear Ltwoo brake caliper had a sticky piston out of the box. First thought it was uneven brake mounting surface, but just replaced with the other spare wheeltop caliper. No brake rub at all now.
•   Bleeding brakes is really easy on TT brake levers without having to stretch rubber hoods out of the way.
•   Since I’m not running front mech, to charge the battery I will have to unplug rear mech, plug in front mech and then plug that into USB-C charger. No big deal.
•   Haven’t added up total cost, but without wheels/tires/rotors am guessing this cost me less than $AUD4000, which is a bargain considering a Giant TT frameset alone is around $6000.
•   Will add a front chainring guide soon for peace of mind.

I’ve done three decent rides on it and am slowly dialling in my fit. I sit in UCI height category 2 (180-189cm) so have set up extension reach to comply. Am now looking at the Winow ARB02 extensions (which I’ve been told by Winow will fit to the existing adaptor plate). Am still figuring out which size to order so that they don’t exceed my category limit (830mm from centre of BB to tip of extension). If anyone has any experience with this and knows what size ARB02 I should get please let me know.

Note picture shows 140mm SRAM rotors F/R before I changed to DA, chain has been cut (was initially too long), and front mech cable sticking out has been removed.
