will these components match

[apb]

Hi all

want to do new bike build and was wondering if these components match

Shimano Dura-Ace 7700 9 Speed Bar End Shifters
work with
Sora 3500 9 speed deraileurs. I'm sure the front will, but not so sure the back will.

Regards,

They're both 9 speed so should work fine.

They'll work but you have to stick with Dura-ace cassettes (the spacing on the Dura-ace 8 and 9spd cassettes is different)

Could i just use a Shimano HG50 9 Speed Cassette?

You can, just don't expect it to index fully. You can however turn the indexing off with those levers and they operate fine in 'Friction' mode.

Not sure i want to use the friction mode. I may need to do some rethinking.

I get OK results with an 8spd rear cassette with my Dura-ace 9 speed bar end shifters, I think that is the closest spacing/cog width match (the bar end shifters are 8 or 9 speed Dura ace and the 8 speed spacing was kept but later 9spd was altered)

Ok, i understand your previous post.

So if i use an 8 speed cassette with the 9 speed shifter i get a better result.

I think i may ditch the bar end shifters and go for a new Tiagra groupset, but with canti's.

I have just replaced the DA 7700 front and rear derailleur on my spare bike with newer Ultegra - I got seduced by some low prices on t'internet. Although they are *meant* to be 9-speed the DA7700 parts have been working perfectly with a 10-speed compact set up with 105 5600 STis. Even when running older 105 STI 5500 9-speed , I never had a problem with indexing any cassettes either from SRAM or Shimano. I never owned a 9-speed Shimano DA cassette, just Ultegra or 105. However, this wasn't with bar-end shifters (which is what the discussion is about!)

I still have the DA 7700 derailleurs which are still working perfectly but will probably put them on eBay as a pair soon.

Yep the indexing on the shifters will match the cassette, the mechs only do what they're told to.
