Frame advice - hardtail with a 40T (or more) chainring

[RDY]

Thanks! Yes it's a boost frame with 42 chainring I think that a 44 also will fit. Size off the frame's are XL and L.

Looks like a 46 round or 44 oval will fit.

Is that 52mm Boost with +3 offset chainring?

[mermlundry]

Here it is, with 42th chainring, pf4624 bottom bracket, full shimano XT and Elite Pro36 wheels.

Thanks for following up! Happy with the Airwolf frame? Built up ok?

Yes it is 52mm boost but with 0 offset chainring.

Yes frame is ok but I am no expert on this subject. Build complete for my configuration is 9kg.
The first frame I ordered came in damaged so I contacted Airwolf and send them photos. They directly send me a new frame so I was happy with that

Only problem I have is that the B-gap is almost 1cm so changing gear is slow, but I think that is the fault of a to short chain lenght. I did exactly as shimano says in the manual 5+chainlink. So I going to extend the chain and see what happens.

where did you get the fork?  is there another link for that frame that has the fork or did you just request it from the frame builder?  i am looking at the link that is posted and it is frame only.

If you look in the description of the frame on AliX, Airwolf has a rigid fork to go with the frame:

I did 2 build with this frame and fork aswell. We just ordered both on AliX, payed for the "Seller shipping method" on the frame (so we didn't have to pay import tax in Belgium) and messaged Airwolf to ship the fork with the frame (fork was ordered with "Standard shipping").

Not sure if Sven had to pay extra to get the paint on both the frame and fork since we ordered matte black and painted it ourselfs.

Trough the chat with https://airwolfcarbonbike.com/ you can request the fork in the same color.

B-gap problem is solved by extending the chain with a couple of links.
I have the 10-51 cassette on the XL frame and the 10-45 on the L frame. The 10-45 b-gap is perfectly aligned but with the 10-51 there is still some space left although the screw is fully loosened. Shifting goes faster on the 10-45, so I would advice that for future builds.

Any xc frames that can take 40+ chainrings?

Any xc frames that can take 40+ chainrings?

The mentioned Airwolf frame is a XC frame:

Have you seen story about the Airwolf YFM-026 on bikepacking.com? See also the comments with an update. Spoiler alert:  he isnt'using the frame anymore. https://bikepacking.com/news/readers-rig-willems-airwolf/#:~:text=Our%20Reader%E2%80%99s%20Rig%20of%20the%20week%20comes%20from%20Willem%20Schouten

I was wondering which frame you have choosen. The Seraph/TanTan FM199?

Do you know what the max size front chanring will fit on this frame?

Hi!

First of all, thanks for letting me join this forum. I've already trawled through a few of the threads here, and wow what a massive treasure chest of information.

I am looking for a XL sized hardtail frame (not gravel, just a regular hardtail) with the ability to fit a rather large chainring (40T or ideally 44T). So far I've eyed the following:

• Spcycle SP-M028 https://www.aliexpress.com/i/1005003519445706.html
• Airwolf YF-M026 https://www.aliexpress.com/item/1005005254091618.html
• Spcycle SP-M030 https://www.aliexpress.com/item/1005005180265369.html
• Flyxii FR-701 https://www.aliexpress.com/item/32885761409.html
• Ceccotti MF05 https://vi.aliexpress.com/item/1005002201546421.html

My findings/opinions about these frame so far:

Spcycle SP-M028
Unknown chainring capacity (question sent to seller), nice design, good geometry

Airwolf YF-M026
Max chainring 44T according to seller (after asking), bulky design, good geometry

Spcycle SP-M030
Max chainring 36T according to listing, ok design, good geometry. Might be able to fit a 40T with more offset on the chainring?

Flyxii FR-701
Unknown chainring capacity (question sent to seller), quirky design, good geometry. I guess 40T shouldn't be a problem, but with a large cassette there might be some limitations. Not a fan of the design though.

Ceccotti MF-05
46T chainring capacity according to seller, nice sleek design, somewhat cramped geometry compared to the other frames.

Seraph/TanTan FM199
According to various posts here this frame should take a 42t or possibly 44t chainring. Nice design, nice geometry. I think this might be the one.


Are there any other alternatives that you know of that I should consider looking at? It doesn't really matter if it's boost or not as long as it's a big frame (21"/XL) and can fit a 40T (or larger) chainring.
