The hope IBR seems very expensive for a part that will wear out – when your chainring werars, your bash goes in the bin too. It’s just a bad idea – maybe if it wasn’t 2-3 times the price of a standard chainring, but as it stands, it’s not for me.
For XC, I’d go with a regular chainring (Hope ones are lovely) and an MRP 1x guide or similar, and shouldn’t add any weiught.
A clutch detailleur is a nice thing, definitely get one if it’s in budget. That’ll ensure your chain goes nowhere.Posted 4 years ago
I am looking to run my new frame as a 1×10 setup. I have an XT M770 chainset which I am looking to run a new Hope IBR 36t chainring on. Couple of questions, will a KMC x10L chain work with this chainring? Also, what is the best chainguide to get – Hope sell one that goes with the IBR which I could fit on the seat-tube. Any other suggestions? Is the rear derailleur important in terms of type? I am mostly doing XC riding so any advice would be appreciated…..

Biggest advantage with 1×10 is 36t cassette. It’s not available in 9 spd unless you get the boat anchor one, that really does weigh a lot. Plus it will trash an alloy free hub. I ran 1×9 for a few years but the 36t just gives you a teeny bit more bail out on steep climbs.
Only ever used a Superstar guide, & its a faff but works fine once done. After faffing with shims I resorted to “shaping” the bracket to suit last time.Posted 4 years ago

What do you reckon on chainring size for a 1*10 setup? I’ve got a 32 earmarked, also got a 36 from a 2*10 setup or could also press my tazzy wobbly 34 into action. Its on a 29er, so with a 10% wheel size difference = 10% on the gear inches, I’m thinking 32t at the front will be broadly the same as a 35-36t front on a 26er, ie; plenty tall enough for me.Posted 4 years agoedoverheelsMember
Unless you are trying to re use existing parts there is no point in going 9spd. 10spd means lots of 36 cassettes and more importantly clutch mechs. Only need a shortcage mech and a top guide of some sort (my preference is Paul’s Chain Keeper) for silent fuss free running.Posted 4 years ago
Not too hard to get 9 speed cassette and shifter to work with a 10-speed mech, as long as you use the right bits (SRAM shifter, Shimano mech). But 9 speed trigger with 10-speed cassette won’t go (well, it probably will with enough attention, but would be completely pointless)Posted 4 years agomikewsmithSubscriber
I dont get it
Shimano add 2 teeth to the cassette and suddenly its ok to ditch 10 or more teeth at the front?
Yes No Maybe
It entirely depends on you, what you ride and how you ride. Other peoples mileage WILL vary.
One of the key factors in Cadence, the faster you can spin the lower you can get away with the front ring being, if you can’t get the high rpm going (and be happy with it) then you need a bigger front ring and will have to grind harder up the hills.
Next where you live? Is it hilly? Most trail centre riding have nice climbs which take the angles out (most means not all) and let you go “middle ring” all the way up. Mountains tend to be designed slightly differently and can get steep fast.
If you find yourself dropping to the low ring a lot 1x anything will probably not work. If you can hack the bigger ring then it’s an option.
Back in 09 I got a new (second hand bike) with 1×9 (36f,11-34r) it was a heckler and I rode it for over a year in that config, I was fitter and stronger then not much got the better of me till I moved back to the lakes. That didn’t work for me so well 25% hills were an issue.
Long and the short look at your riding and how you are doing and go from there.
Be interesting to see how the Hope ring lasts, I had an E-13 guide ring on my 1×9 setup and it never looked used years down the line and ran as smoothly as day 1 until I bent it.Posted 4 years ago
Here is the end result – 1×10 based on Hope 38t (yes big but doable on most bits) chainring / XT chain set / SLX 11-36t cassette / XT mid length derailleur and superstar chain guide… built into a Cove Handjob with other Hope kit to boot……Posted 4 years ago
