Afternoon all,

After a long time off with injury I am just about ready to release the bikes.

I have a Lapierre X Flow 412 which i am hoping to convert to 11spd (Shimano XT 1×11 Complete grouspet i was going to buy).

Are there any precluding factors where this would not be possible?

Many thanks for the help. 🙂

Ash!!

I cant see anything wrong with that set up.

Welcome back, enjoy!

Why ?

Easy enough, just don;t forget you need a different free hub body.

Not for shimano…

Free hub body, whats one of those?

My knowledge of bike mechanics is incredibly poor, I can do stuff on the go (chain link, tube replacement) but anything beyond that and i’m stumped!!

Ash!!

It’s the bit that joins the rear cogs to the rear hub. Shimano uses the same one across ten and eleven speed, sram has a different version for some of their eleven speed cassettes but not all. If you’re using a Shimano cassette you don’t need to worry about it

Thanks Akira, no need to panic on that front then.

Next up is options:

32T x 11-40 175mm
32T x 11-42 175mm
34T x 11-40 170mm
34T x 11-42 170mm
34T x 11-40 175mm
34T x 11-42 175mm

Whats the best from the above?

As you can tell, I buy bikes, ride them and then take them to the shop to get fixed if they break or need servicing. This is really the first time i’ve decided to swap anything up.

Thanks again.

Didn’t know that, interesting. Is a shimano 11speed cassette compatible with a Sram chain?

So the last number is the crank arm length. If you dont have a preference I’d just check the current cranks on the bike they’ll say what length they are somewhere.

The first number is the front chainring size (number of teeth), depends how fit you are and what kind of terrain you’ll be riding.

Same for the middle numbers 11 is the number of teeth on the smallest cog of the cassette and 40 or 42 is the biggest cog. Bigger cog equals lower gear.

Essentially these combinations allow you to run the same top and bottom ends of a triple chainset. There are gear ratio calculators on the internet if you want to get super nerdy.

Sorry if I’m teaching Granny to suck eggs, just trying to be thorough.

I don’t know. Someone will be along soon to inform us.

I just know that Sram use the XD freehub to allow the smaller (10 tooth) high gear, whereas shimano use an 11 tooth high gear and then “float” the lowest gear in towards the spokes on a spider thus using a standard 8/9/10spd shimano freehub.

Thanks JackHammer, really appreciate it.

In that case i think the below would be a good idea?

32T x 11-42 175mm

Good price for the full groupset on ****** too.

Ash

Sounds good! You’ll probably need some tools etc to fit it all once it arrives. Everyone on here will be happy to talk you through the process of fitting the parts etc. Also there are some good videos about on youtube etc. Al Vines’ ones for MBR or MBUK (cant remember) are pretty good if he’s done one on fitting cranks etc.

Do you get shifter, a mech and chain as well?

Thanks JackHammer.

I will get the order placed and if i get stuck, return for info.

I read the forums alot, but usually i hunt out pretty pictures of bikes opposed to the techy stuff lol.

Cheers.

Ash!!

Apologies, didn’t read the last question.

Not sure if I can place the link on here due to advertising etc.

So i’ve stolen the description:

Specification
Shimano XT M8000 11 speed cassette
Shimano XT M8000 Brakes front and rear (without rotors)
Shimano XT M8000 Chainset in choice of crank length (170, 175mm)
Shimano XT M8000 11 speed rear derailleur-Long cage
Shimano XT M8000 R/H shift lever (I-Spec II)
Shimano XT 11 speed chain

Cool! Yeah looks wikid!

Is a shimano 11speed cassette compatible with a Sram chain?

Yes. Use split links, only pop the chain to shorten it.

Personally, I would get cranks that gave me the option of going below 32T, but that’s a personal thing.
There are some aftermarket 30t rings that fit those cranks I suppose.

Unless you are particularly tall, I would also consider 170mm cranks if you have the choice. Fewer rock strikes on a full sus.

Thanks for the advice everyone.

Ash!!

The XT cassette comes in an 11-46t flavour. Worth a look. For some extra range.
