I changed my BFE to 36 x 11-40 I was using it for commuting around Dundee (excellent cycling town IMO) one Sunny evening I decided to drive over to Balkello and have a mooch, the climb up to Balkello Fort shredded my thighs, some of the locals on their bouncy bikes regarded me as some kind of maniac, but were very pleasant nonetheless.

32 oval, 11-42 works well for me on everything except very steep hills that can be a struggle.

32 oval – 11/50 di2, ALL, CBF 😆

34 tooth oval chainrings, running either 10-42 or 11-42 depending on wheels. Riding 650B hard tail or 650B full sus, both set up very XC race.

Live in Leicestershire, so rolling countryside. Pretty fit (can normally hold my own in Expert cat XC).

36t round, 11-40, 29er 120mm/100mm xc FS. Mostly use only as my XC race bike, bit of sunny Chilterns singletrack, the odd Afan visit. Whippet.

30R 10-42 27.5 Fs 150mm mountains
34oval 11-42 26 hardtail
30R 11-50 fatty hardtail

Love the 1×11 setup but would still like a lower gear on the Fs.

42 (round) 11-36 for a bit of variety!
Gnarmac. Just got back from 2/3rds of Dr P’s tour de SE England…..

34t round
11-40 cassette
Rigid 29er
Everything- Touring, bikepacking, trail centres, hill climbing, Yorkshire moors riding (don’t know how to label this)

Honestly would prefer to fit a 36 or 38 for the touring stuff but chainstays are too broad so I make do.

Wife has the same but 11-46 so it gives the same bottom gear as her old 3×9.
