Help with Cinelli Mash CXSS build?

Hey all -

I've finally got my hands on a Cinelli Mash CXSS frame in my size and was hoping to dip into the LFGSS community well of knowledge for some guidance on the rebuild. Ideally, I'll have the bike set up so that I can swap out the wheelset depending on if I'm in the city or out on the trails, which I'm hoping is viable. So, any suggestions on upgrades in either cyclocross/city mode? I have a wheelset pending (Shimano Dura-Ace Low Flange Hubs/Sapim Spokes/Mavic Open Pro CD rims) that I'm hoping to use for city cruising, either fixed or ss.

This is the current build:

Frame: Cinelli Mash CXSS (56cm)
Wheelset: Halo Evoura wheels with flip flop hub
Hub: Halo Clickster 18T freewheel
Tyres: Schwalbe G-One Allround 40mm tubeless tyres (with an additional set of DT Swiss 460 rims laced to Miche Primato hubs, Sturmey Archer 20T freewheel)
BB: Sram GXP
Crankset: 38T Superstar Components oval chain ring on Sram Rival cranks
Seatpost: Cinelli Vai
Seat: San Marco Era
Stem: Ritchey (?)
Bars: Deda RHM 01
Brake levers: Sram
Brakes: Avid Shorty Ultimate Cantilever

First-time poster, so apologies if anything is out of order.

It’s viable, but impractical.

Just ride it in the city in cross mode, or build up another bike. I’d go with the former personally.

OK, thanks.

Impractical because it would require more than changing out the wheelset, or just unnecessary?

Concur with Tijs, second wheelset is a ballache particularly with cantis. I run the same brakes on a Cinelli Mash Work and if you even glance at them the wrong way they'll go out of whack and start shrieking like mad or just be totally useless. Great brakes if set up perfectly, swapping wheels in and out will throw them off kilter and fuck you off no end.

Also, 38x18 is mad spinny for city, even on 40s. There's a thread somewhere discussing ideal city ratio and consensus seemed to land around 66 gear inches +/- a few either side.

Was gonna say that. I rode a 42x18 recently and spun out at maybe 18mph on a flat road.

Appreciate this. I'll also find that thread about gear ratios.

Here ya go, most recent one I think:

I'm sure there are other threads along the same lines.

I’d ditch those cantis asap and fit either some proper smooth post pad cantis or some mini vs.

The idea of a canti that takes a v breaker pad is nice but I’ve tried a few of them and for whatever reason they just seem to work terribly compared to a proper canti. It might take you a few minutes more to set up the brakes initially but it’s worth it.

Mini v are particularly shite with the cheap tektro levers but your Sram levers might work better with them.

I think if you change the brakes and use the same rims on the other wheels then swapping would be ok.

Would you be running the same gearing though? Might be a bit counter productive to do so but moving the wheel back and forth for different gearing would/could necessitate moving the pads.

Thanks. Can you recommend any brakes?

Figuring out the gearing is on my to-do list. I wasn't envisioning swapping out the wheelset frequently, but ideally I would keep the gearing the same.

I concur with the wheel changing faff. You don't want to be resetting cantilever brakes. You'll go to a dark place if you do. Keep those Shorties for sure. There are not many cantilever brakes better than those.

SS/FG is always compromise. I currently run 40/17 (≈64 GI) but changing that next week to 34/17 (≈55 GI). Spinning is better, in my opinion, than labouring up a hill wondering it your patella is going to pop like a champagne cork. That said I'm old and fat and you might not be. That's on the assumption that you're going to race or engage in mixed terrain riding. If it's just around town go for more GIs.

I have always liked the Mash SSCX. I hope the build goes well. TBH I don't think that there is much on that build I would change (apart from the frame being XXL).

Edit: BDHU or you'll be in the BDHU thread.
