Will 11-32 cassette be okay with my RD and triple chainset?

I am planning to buy an 11-32 Tiagra 4700 10 speed cassette for my steel touring bike. It has a triple up front (50/39/30) and I've read that as my Rear Derailleur is a 105 Medium Cage GS-5701 it is only compatible with up to 30T cassette for a triple, but a double can go up to a 32T cassette.
As I would never intend going on to the 32T sprocket when on the big 50 chainring, am I right in thinking the cassette would definitely be okay with my set-up? Just wanted a second opinion before I buy the 11-32 cassette.

With a triple chainset I would choose a 28 or 26 as granny ring and leave the 12-28 or so in the back.

5701 capacity is 40t
with 11-32 and 50/39/30, you've got 20t on the front, plus 21t at the back, 41t, not much in it
as long as you have everything set up right (esp. b-tension and chain length) i'd think you'll be ok - it's not whether or not you intend to use the 50/32, if it happens by accident you need to be sure it doesn't cause a nasty surprise!my bike - faster than god's and twice as shiny0 -
Thanks but just got that triple chainset last year and it's all in one rather than separate cogs that could be replaced, so will have to keep the 30 granny ring.Keezx wrote:With a triple chainset I would choose a 28 or 26 as granny ring and leave the 12-28 or so in the back.

Thanks, I know what you mean. However I think if it was a compact on the front there would be a chance of me going 50/32 by accident, but I think there is less chance of me doing it with the triple, as I tend to be in, at most, the middle 39 ring on any sort of inclines, and can't think of any occasions where I have slipped into 50/27, my current smallest sprocket on that bike.sungod wrote:5701 capacity is 40t

I was originally going to replace my 12-27 with a 12-30 10 speed, but Tiagra only seem to do 11-32 or 11-34 at 10 speed as far as I could see.0 -
I've got exactly the same set up on one of my bikes. The others are all compacts either 10 or 11speed. The triple plus 11-32 is the smoothest to ride from a gearing point of view of the lot and the set up works very well.0

What does Shimano think at 11-32 , why give up useful cogs for an 11?0

I agree - I don't need the 11. A 12-32 would do fine if it was available.Keezx wrote:What does Shimano think at 11-32 , why give up useful cogs for an 11?0 -
Thanks, that's good to know - I think I'll get it then. I agree with you about triples - I have two bikes with triples and one with a higher spec compact, but I prefer the triples.Clickrumble wrote:I've got exactly the same set up on one of my bikes.

I agree. Set your chain length on big front /big back just incase you do go into this combination. This may leave you with a dangly chain in small/ small but you will never intend using this and it is no problem if you do.0 -

SRAM do a 10 speed PG-1050 12-32T, the Shimano CS-4600 10sp 12-30T is discontinued, though a CS-HG500-10 12-28T is available.0
