New Gravel Frame Ican Graro

[fnkymnky]

I just received all parts for my Graro build in silver grey fade. Plan was to build it up with Ultegra FC-R8100 2x 50/34, but it just won't fit. Without spacers, as recommended by the instructions of the Praxis t47 IB bottom bracket, the chainrings are contacting the frame / chainstay. With spacers on the drive side, the chainrings have enough space, but then the left crank arm can not be put on all the way...
Since I read a few posts about 2x working fine, is it crankset specific or what am I missing?

I would contact Ican, it looks like they they fitted a 105 to Graro in the picture.

I fitted a 50-34 with a rotor 3d chainset and power2max PM, that has a chain line of 43.5 so I've added 6mm of spacers although I think I could get away with 4mm.

I was also able to fit 52-36 chainrings but there the height of the front derailleur was a couple of mm to low so I bought one of these adapters to give me the height I need as I intend to use the Graro for road time trials over the summer.

I reached out to Ican and got a quick reply and you are right, only the latest generation 105 crankset from the Shimano Road Crankset portfolio will work apparently.
Should have just calculated it before, but the 86mm (or 85,5) BB Shell + the 2mm per side from the BB adds up to 90mm width. And since the Ultegra Axle lengt between crankarms is just 90mm there is no room to put additinal spacers. Now I am undecided if I will go with GRX after all or try with the 105.

I would not worry about that. Looks like a paint chip to me (bad paint prep???). Too bad it's such a visible place

Finally my frame come to me 10days before estimate shipping. From EU warehouse. Dont like the hologram color of logos but who cares.

Weight 8.12kg without SPD. Not bad, specially if I use 10-52 cassette.. RED with powermeter, 180/160mm brakes wit RH4+ calipers and 45x700c tires.

Looks great!! How easy was it to align the rx4+ calipers? I read a lot of people are having trouble to get them noise free. Was also thinking on upgrading to them

SO, long story short. I bought Graro with integrated handlebar, but lost some of the spacers. Are there any compatible spacer available on AliExpress?

Hey, did anyone of You tried to assembly Your Graro to wahoo kickr core? Have You had any issue doing it? Im having issue when im screwing rear axle to the cassette its stop moving backward (chain doesnt work properly, it locks on cassete). It looks like the adapter it came with is too small (142mm). Im using sram apex axs and HG cassette

Take a photo how it looks without mounted frame. The cassette and spacers.

 I had my graro in tacx 3t without problems.

Going back to chainrings has anyone managed to successfully fit a 46t 1x chain ring?

I tried to swamp out the 2x 50-34 set up to a 1x 46t, both set ups using Praxis chainrings but the 1x chain ring is almost touching the frame. For both set ups I used the same chainset spacers were are maxed out to make the rotor cranks mirror the chain line of GRX chain sets

From what I understand , the 1x looks to have a 3mm offset to reduce the chain line,  although this is not listed on the praxis website it seems pretty common in 1x  chainrings when I was looking into this last night.

I'll go back to 2x for the time being and start to looking for zero offset 1x chainrings as they must exist?

Could you run the 1x chainring as the outer chainring on a 2x GRX chainset and then not run the inner ring?

Thanks for the replies

I sorted out the 1x chainring issue with a Stone zero offset chainring.I'm really impressed with the quality and finish and it came with what look like chainring bolts specific to the chainring as when I tried to use them on my CX bike with another chainring they were too long. I've still got to shorten the chain a little bit and fine tune the chainset sitting but it handled a hard hilly ride while not optimal with any issues and slipping.

I've also upgraded the wheels and got a set of 29mm internal wheels from Carbonal which has bumped up the 47mm specialized Tracers I use to 51/52mm I do like the monster truck vibes but I may have to look into downsizing to the new 45mm tracers if there's any tyre rub

Could you take a picture of the clearance between chainring and chainstay or measure it? thanks
also currently trying to figure out if I want a 44 or a 46, but since you mounted a 46 at GRX 1x chain line, I'm leaning towards that.

[gofasterstripes]

Here you go, there is 2-2.5mm space between the chainring and chainstay, I'll probably add another 0.5mm to the chainset once I've got everything dialed.

From memory I had about 3mm gap when it was set up 2x with a 50-34( I think I mentioned the gap in an earlier post)

I measured the gap between the tyres and frame and even with the increase in tyre width to 51mm I've still got 4mm of space each side, which surprised me

Hi everyone! I have finished building my gravel bike on the GR201 frame. When I saw the finished
frame I was afraid I would have to repaint the whole thing because it seemed too bright and colorful,
but after adding the rest of the black accessories I now think it turned out quite interesting. The
weight of the bike weighed like in the store (without accessories and pedals) pleasantly surprised me,
even though I switched tires from Tufo Thundero to Specialized Pathfinder, where each tire is 100g
heavier the weight was 8,29kg. After adding Zeray pedals, bottle cages, Garmin mount, mirror and a
fairly heavy bell, the weight increased by 500g to 8,79kg. I am 186cm tall and the frame size is 56cm -
in my opinion ideal, although now I would order a 100mm cockpit instead of the current 80mm. I was
afraid that the position would be too aggressive, but for now it seems very comfortable
