SRAM x9 to SRAM Rival

[sayek1]

Hi,

I am looking at converting my hybrid to a drop bar bike and will be changing to SRAM rival shifters. I currently have X9 rear derllr and was wondering if I would need to change this to Rival as well - also the rear cassette (currently 9 sped)? What about the front one as well?

Thanks for any advice. The bike is a Boardman Hybrid Pro - no changes to standard spec to date.

Thanks

Can anyone help me with this question please?

Thanks

bearing in mind I'm not familiar with SRAM gars - I'd have thought this bit would be ok - however you may need to look into the pull of the brake levers and whether they'll operate your brakes sufficiently - hopefully someone will pop along with better answers.....

I think you might to change both derailleurs...but the cassette would be fine.
As Patrick suggests the big problem you will have is the brakes, if I read the spec of you bike correctly it has hydraulic discs? Even if it has cable operated discs they are still not compatible with Rival levers.

The answer is No, the rear mech is compatible.

Thanks guys - it looks like its a no - which will add extra costs. I have established that my hydraulic discs need to be changed for mechanical ones (BB7) and with these and the rival shifters (and bar, stem, cables, tape etc) it looks like it will become prohibitively expensive. I might just sell the thing and go for a cx bike from scratch (CDF maybe). This replacement derllrs is probably the final straw as this is likely to tip the costs around the £500 mark - not worth it on a bike that wasn't designed for this. If I can sell the bike for £600 then I may as well buy new and live with Shimano gears rather than SRAM.

If you look at SRAM's list it suggests they are fully compatible, provided of course you do not violate sprocket number, size limits and range limits etc.

As you can guess I am not a mechanic............ I have the X9 derrlr on the back. This has a 9 speed cassette - I am assuming therefore that the derrllr is 9-speed. If this assumption is true I am guessing that it will not work with the SRAM Rival 10 speed shifters - I think these shifters only work with a 10 speed derrlr and cassette?

Am I right in believing/assuming these things ie. are derrlrs 9 speed OR 10 speed and they cannot be matched with a cassette that does not reflect the same.

I'm not sure on the front derrlr, but will check this out.

Thanks

The cassette has to match the shifter - if you are buying a 10 speed shifter it will only index properly with a 10 speed cassette. The road components are compatible with the mtb components on the list.

However strangely other SRAM mtb components do not actually have exactly 1:1 actuation although they have been marketed as such, and therefore are incompatible with the "Exact" components.

I don't think any of it will be fine.

Sram rival is 10 speed so your 9 speed cassette wont work

Sram x9 uses a 1:1 lever pull / acuation ratio wereas the Rival shifter use 2:1. In other words your rear mech wont work.

A MTB front mech wont work with road bike gear levers and a road bike front mech isn't going to like being used on a MTBs chainset. Although you might find a fudge you're potentially looking at a new chainset and bottom bracket.

As your new chainset complete with larger chainrings might now foul your frame; and given that flat bar frames normally have a toptube thats about 4cm longer than the equivalent sized drop bar frame you'll need a new frame aswell.

Now your forks will probably wrong, and the rear wheel will be too wide.



Getting the idea?


You can convert your bike to drop bars but it's always going to be a something of a bodge.
Save up and buy a proper road bike or fit a different type of bar / bar ends.

 

[RedBike]

Scrap that.
Apparently Sram rival shifters do have a 1:1 pull ratio!

 

[sayek1]

I think I've pretty much decided to save my money on converting and sell the flat-bar and invest in a good cyclocross bike even though it doesn't quite have the componentry I fancy 100%. At least it has the disc brakes and half-decent Shimano gears.

Thanks for everyones help.

sram x9 mtb shifters pull too much cable for a rival road mech, I've tried it it doesn't work.
obviously therefore a rival road shiter doesn't pull enough cable for a x9 mtb mech.
