What GS for a heavy bike?

I had a custom steel cx frame and fork made here in the Philippines and it weighs abt 6kg alone. What groupset would u guys consider for an all around touring bike, a compact 50-34 road gs with 11-32 cassette or a slx 3x with 11 42? Would it make sense to put a road gs on a heavy frame?

22-32-42/44 chainrings.

Cassette depends on your terrain. But i chose 12-32 on my 26" bike and so that i would and am never short of gears low or high.

In my lowest gear (18.75") i can pull a trailer of about 40kg up some significant slopes.

GS= group set? people ride road bikes touring the coast here, not many, but some..

1st week in June there is another Transamerica race-tour they are racing along a touring route, to Virginia's shore..

so what style your tours will have , is a choice to make .. go fast carry little, like the above..

or more Camp comfort, self contained more, slower, and enjoy the scenery.

Wow 40kg, by heavy I meant half that or 15kg even 😄.I've tried carrying 15kg with a MTB with 2.1 inch tyres with this CX I plan to use 32mm. Yup I guess bigger chainring 44 would compensate for thinner tyres and not make me over spin I guess that would be perfect thanks man 👍

Yup GS = groupset. Looking forward to Transamerica wheel race too, I want to go fast and carry lite but am not really sure w/c crank set to go for wether a road or MTB...for the cassette though it's definitely a 42 for spinning. Btw I could be wrong with the weight of the frame, anyway I guess it's not much of a factor sorry for the wrong header 😅

42/11x26=99
42/11x27=103

44/11x26=104
44/11x27=108

Don't worry, you won't overspin it, especially loaded and fatigued. Lol.

If you do, simply swap the big ring. Problem solved.

Sustained speed ambitions? Road triples are 53, 39, 30. The mountain compact triple, is already covered.
wide doubles, common, 50, 34, uncommon, 46, 30.


Used a 50,40,24 for many years/tours.. was 13~34t freewheels for the most part.. CX being a wider 700c wheel that was similar,
though for touring weight , they were heavier wheels..

now have internal gear hubs , potentially mix with double chainsets to extend the range wider if you choose..
Nexus 8 speed IGH work well not too expensive..

Trekking bars work well with grip shifters made for MTB bars (22.2mm tube)

34 X 32 is not a very low gear, if you're riding flat you could get away with it, but once it gets hilly, I think you will be struggling. But, I am not a very strong rider
I would base road or MTb gearing on the handle bars: Flat bars- I would use MTB, drop bars- I would use road.

13.5 pound frameset? Why?

Even stout framesets like the LHT are about 6.5 pounds. Why is yours twice the weight?

Not really sure why, but the frame is made from high tensile the drop outs are built in the frame solid not sure if the tubes are butted either so I guess it adds to the weight...

I would gear it MTB...

Forget your dreams of riding fast. First of all, the frame is a real hog at 6kg. Two, you'll be touring, not racing, right? Three, i know your terrain, steep climbs, for i live in Indonesia with similar volcanic, island terrain. Gear it with a Shimano Deore 6000 10-speed 38/28T double crankset, and 11-42 cogset. Forget the 'road' groupsets, and dreams of high speed.

You can use mountain bike gearing with drop bars, too.

I run a CX bike as one of my touring/bikepacking rigs. Right now gearing is 48-32 up front and 11-32 on the rear. I had a 11-36 cassette on it too but went with 11-32 after it wore down...probably could have gotten a 11-40 cassette to work with a derailleur extender. I live in a mountainous area and it works just fine for me, YMMV on that though.

Had it painted today just to update cost me about $6 US only!! Hope it turns out good. I guess I'll have MTB gearing 3x with 48 up front and 11-40. Thanks for all your inputs, this really helped me decide and consider things abt touring

Hi, I dunno if you already have this solved. I also have a Maldea CX (Hi-ten frame & Carbon fork) and I currently run 11spd with a 50/34 compact chainring and 11-40 cassette. It works for me, hauling 10kg of the bike + 75kg rider + around 5-10kg of bikepacking/touring equipment depending on need. Decent for steep hills but would probably change my chainrings to a 48/30 in the future.

Hi, I actually havent gotten a groupset yet ive been going around metro manila and local online shops for a sub compact crank but no luck so far. btw what rear derailleur do you use for your 11-40? ive seen people use road bike derailleurs with MTB cassette with the help of a roadlink but i wanna see long term reviews the RD just seems too stretched out for me that it could snap XD

I'm using a mid/long cage 105 rd (the previous version). It's actually okay even after 4 months of use. Just don't crosschain it, crosschaining isnt even advised in regular setups anyway.

I'd upgrade mine with the new ultegra rd with the clutch system in the future, but for now I'm pretty content with how it performs.

S-A , the remaining hybrid hub, combines a cassette driver and 3 internal hub gears.. in low in the hub, whatever gear you have on the cassette

is now 3/4 of that ..a 34, acting as if a 42t cog
