130bcd 52/38 tooth rings for 11s???

[JimmyTango]

I've searched and searched, but cant seem to find any 11speed compatable 130bcd rings in 38/52 combo. Does anyone know if they exist or where to find them?

I've found a few 38t fsa inner rings listed for 10 speed use... can I use that on my Sram Red Exogram crankset?

I've been running standard rings for years, but I want some more gear and I think just dropping a tooth on both rings could be a step in the right direction without having to buy new cranks, but it's looking surprisingly sparse on ring options.

Ideas?

Stronglight makes the biggest selection of rings and they are very high quality.

Thanks. I see that Stronglight's website lists a few options that could work for me, but finding that combp from an actual retailer is challenging.

To be clear-- can I use a 9/10 speed compatible outer ring with an 11s inner ring and an 11speed chain?

You can try, but it's not guaranteed to shift well if the chainrings weren't designed as a pair.

Keep in mind that your proposed change only reduces your low-end gearing by a couple percent. To get a sense for the magnitude: the shift between a 13-tooth cog and a 14-tooth cog changes your gear ratio by about 3 times that much.

I would recommend dealing with a retailer that can order the rings that work best together.

Like Tupo said, the gearing you are looking into isn't that big a change. I don't think it's worth keeping a crankset and swapping rings. Better to get a crank with the smaller BCD and the lower gears already installed. There are entire cranksets like Shimano 105 that are cheaper than some chainring combinations.

Yeah just go for the FSA rings. "10s" rings will work just fine on 11s.
I thin the bigger question is, what cassette range are you running?
