how wide does it have to be?

Hello,

I have a bike i'd like to upgrade to an 11 speed cassette, but i was curious how wide my freewheel has to be to accomodate the 11 speed. i'm currently on 9 speed tiagra, but i'd like to move up to 11 speed 105 on my commuter.

i measured it at 35mm but i dont want to try and get a cassette only to have to return it if it doesn't fit.

Why do you want to spend so much more money on your commuter, ?

the brifter has to be replaced, probably the wheel , & rest of the drivetrain..

N+1, buy a Whole new bike for the weekend with those up to the minute new components..

36.75mm is the official Shimano spec, but Mavic 37mm freehubs work, too. The latter have been around since at least the early 2000s so if you happen to own a set of Mavic wheels you wouldn't need a new hub. However, it sounds like you have a standard 8/9/10 speed freehub given your 35mm measurement.

There are plenty of cheap 11 speed compatible wheels available as one option, or you could rebuild your current rear wheel with an 11 speed hub assuming you have a quality rim and know how to do the work yourself. Otherwise, given the cost of new spokes (not 100% certain but quite likely necessary) you'd be better off just buying a new/used compatible wheel. Unfortunately, you can't just swap the freehub.

11 speed 105 groupsets can be had for a little over $300. A new rear wheel might cost $100. I don't feel like that's an outrageous price to pay for a bike that gets used very often. I've spent far more building bikes that barely get used at all

The short answer is that 11-speed cassettes won't fit on 9 speed hubs.

so while disappointing, this was super helpful. i guess now my choices would be to upgrade to Tiagra or go for some older 10 speed 105 or ultegra stuff to put on my bike.

i wanted to upgrade because the Sora stuff that is on there now never seems to hold an adjustment very long and while i do ride the bike in all types of conditions - my perspective is that even though sometimes the ride is miserable (cold rain, snow, etc.) i'd still rather have something that works when i want/need it to and work well as opposed to maybe the gear wont change this time...

i'm not a bike mechanic, but i'm mechanically inclined and it seems like this sora groupset isn't cutting it for me.

what does anyone else think/

In my opinion, there's nothing at all wrong with 9 or 10 speed... or even 7 or 8, for that matter, especially on a commuter. Are you really going to miss one or two cogs? Were it me, I would buy a set of used 105 (or better) 9-speed brifters and RD and call it good. Check the auction site and the marketplace here, you should be able to do this for under $75 without sacrificing on condition. If you're averse to buying used, another option is Microshift, which indexes seamlessly with Shimano.

valid point and thanks for the tip - my biggest gripe with this 9 speed is the front derailer. the sora ony has three indexed positions versus the 105's four. and if at any point you try and shift down from big to the small chain ring, you get an awful loud clunk.
i've tried adjusting tension which has helped but again, this wont hold an adjustment for too long.

so maybe all i need to do is upgrade my shifters?

If you are having issues with your shifters holding an adjustment and you've been riding in 'all weather' you need to be replacing your cables and housing before looking at doing anything else. I'll put money (very little, of course) on that being the issue assuming they haven't been changed recently. I had a similar problem with a Sora triple FD not holding its adjustment over a few rides. Turned out that the barrel adjuster had so much corrosion in it that it was winding up the housing when I turned it. Vibration would cause it to unwind and undo my adjustment over time. Simple fix.

A 105 group is $362.51 on Ribble right now. I paid $311.11 last August.

That and a new set of wheels has my 14 year old Fuji refreshed and ready for the next decade of use.

11 speed cassettes will fit many Mavic 9 speed hubs. Ksyrium SL for example. I have a pair in my closet.

Lucky for the OP if he has such a set.

I paid about $360, too, but I had a pair of ~2005 Mavic Cosmos wheels that accepted the 11 speed cassette. Those bits plus a matching set of Ritchey Classic handlebars, stem, and seatpost made my 1984 Trek 660 into a more than acceptable modern road bike.

The new Ultegra 8000 11-34t cassette will fit on standard 8/9/10 speed hubs.
That is the main exception.

Not impossible. There is a solution to make it work.

I'd guess that, depending on hub brand and parts availability, you could swap the freehub body and redish a little. Maybe a lot cheaper than a wheel.
