- Which size oval chainring, 32 or 34??
Going to be needing a new Hope Direct mount chanring soon and fancy trying an oval one for a change.
Reading up on the web it reckons that a 32 is equal to a 30 for climbing and 34 to a 32. As I currently have a 32 1×11 and don’t use the 42 much anyway. Don’t fancy shelling out nearly £50 and either spinning like mad or struggling everywhere, so any real reviews are grateful
For the record, I ride all over Wales, The Peak, The Lakes and don’t have any probs climbing with the 1×11 32/42 or the other bikes 1×10 12/36

You don’t say what wheel size you are using.
I just went for the same number of teeth as I had on the circular chain rings. It’s definitely easier climbing but I’m not sure it’s 2 teeth difference, what you notice climbing is a much smoother transfer of power rather than a cyclic stomp-ease-stomp.Posted 2 years agoandylMember
Are you happy with your top gear or do you spin out?
If you don’t spin out then go 32. If you do then 34.
I was running 34 (oval) and 11-42 on my 26″ (now switched to 10-42) and am running 32 (oval) and 10-42 on the 27.5″ FS but I do have an 11-46 cassette just in case as I am on 104 bcd cranks so would need to go direct mount to go smaller over without an expensive 30 oval 104 bcd ring.Posted 2 years agomindmap3Member

I’d agree with this so have stuck with a 32.Posted 2 years agohonourablegeorgeMember

Never been convinced by that – it’s not free energy – for a 32t oval you’re pushing a 34 at the storng part of your stroke and a 30 at the weaker part. For a 30t round, it’s 30 at all times. Strong part of your stroke or not, you’ll notice 4 more teeth,Posted 2 years agomartinkielyMember
I swapped a 32T oval for a 32T circular, and found the “normal” ring harder work, but that might be my weedy legs…. The new ring is a Hope Retainer ring, and interestingly it has dropped the chain a few times, where my Works Components oval one never did – though that may be down to me leaving the new 11 speed chain deliberately long in case of breakages?Posted 2 years ago
Thanks for the replies.
Going to swap out for a 32T oval instead this time and see what the craic is.
With riding 600Km or so a month, off road in The Peak, Wales and The Lakes whilst the weathers like it is, it’s not going to be lasting too long anyway and next time I might try the 34TPosted 2 years ago
