[Closed] Going to 30-t from 32 on 29er

I've been running a 30T on my 29ers and fatbike.
Don't miss the extra top end at all. If i'm spinning out in 30-11 I'm on the wrong trail. 😉

I went from 34t to 32t on 27.5 which is basically the same - no loss of top end speed, just spend less time in the biggest sprocket, legs are happier and bike pedals a bit better (more anti-squat).

Only had 30T on my 1x10 29er. Rarely get to the point where I'm spinning out - a gear calculator shows I'm doing 28mph at that point

I'm sticking with the 32, (with an 11-36), I do find the extra speed I seem to carry up hills with the 29er make the gearing work out. Plus its nice to get the speed advantage at the other end of the cassette! Bike build is fairly light though, that helps a lot with gearing choice.

It's only £20odd & 10 mins to try so worth trying out?

I've been running a 30T 11-36 for a couple of years, but found I was using the outer half of the cassette a bit too much (usually in 6,7,8 at the back). So I recently added a 40T cassette extender and a 32T cog to keep broadly the same bottom gear, but move myself up to using the middle of the cassette.

As above, spinning out in 30x11 was never a problem. When I hit that speed, it's not my gearing that's an issue but my bottle.

I've been using a 30T with 11-36 on a 29er for a year or so. I find I start wanting a higher gear than the 30/11 at around 20mph and it's invariably on long roads / tracks with a slight downslope. Though actually, it's surprising how few of those there actually are (around us in the SE, at least)

Unless you have a lot of those "slight downslope" tracks near you, I'd expect you will appreciate a lower gear more than you'll miss the high one.

30t x 11-36 HT here only time I spin out is on flat fireroad between singletrack/riding on road to get to trails, off road you'll only notice when you realise you never go into the easiest gear. It's nice to have just in case though & perfect for the fat bike

I was running my old 26" with a 32t and 11-34. I've now graduated to 29" with a 30t and 11-36 and it's almost the same. The only time I spin out is downhill on the road, so that doesn't bother me, and if I spin out downhill offroad I'm going too fast for my limited abilities 🙂

Try oval instead, the 32T is meant to be as easy as a 30T but as fast as a 34T. They do work though, it's hard to explain but pedalling feels a lot smoother and I seem to be able to spin a harder gear faster.

This.

Anyone else tried the oval ones? I'm somewhat intrigued...

32 x 10-42 sram, all bases covered.

My mate runs one and rather likes it, but he's a bit of a whippet anyway

Just built a 29er and have put a 30t ring on the front, seems to work/feel slightly better than the 32t that I was using previously on my 26er, I spend more time in the middle of the cassette with this set up which is better for the chainline anyway.

When its worn out I may take a look at a 32t oval ring.

If the magic word was Shimano, rather than SRAM, all 1x questions on here would be answered at a stroke, I think. Well, it would for me, at least.

On a single speed yes, felt horrible didn't suit a smooth pedalling style at all, always felt like something was wrong with the gearing (33:17)

From their facebook page, Superstar may have an oval N/W ring out soon.

Similar experience as Rocketdog, i.e. only spinning out on flat fire roads/disused railway tye paths - as soon as one gets a bit of resistance from the gradient or surface, the 30t is the better compromise IMO.

p.s. Interested to read about the equivalent gearing on a 26er, dont wanna hijack this thread though, so will start a new one about it.
