FlyingScot Posted September 16, 2015 Posted September 16, 2015 I have a 11-25 and barely use the 25 tooth. Gauteng is too flat to need anything bigger. As mentioned above, for things like the jock and panorama tour, I would use a 11-27 just to give that little bit extra. I'll show you some hills in Johannesburg...
'Dale Posted September 16, 2015 Posted September 16, 2015 If you love to windmill them hilltops 11-28
Prince Posted September 16, 2015 Posted September 16, 2015 I recently swapped to a compact with an 11- 27. Very rarely use the easy gears but nice to have it available.
26er Posted September 16, 2015 Posted September 16, 2015 I weigh 79kgA-B batch riderI have had both in the last 6 monthsI ride Suikerbosrand(Up to 7% Gradient climbs if I am not mistaken) faster and recover faster with the 11-28
Maniax Posted September 16, 2015 Posted September 16, 2015 11-28 is fast becoming the new standard.I run 11-28. Best cassette by far I think
NotSoBigBen Posted September 16, 2015 Posted September 16, 2015 Flipping heck guys why not just fit a triple crank as well ????
26er Posted September 16, 2015 Posted September 16, 2015 Flipping heck guys why not just fit a triple crank as well I love my triple crank on my MTBAnything from 6-60km/h
BMXER Posted September 16, 2015 Posted September 16, 2015 I like the ratio from 11 to 25, nice incremental steps.
Frosty Posted September 16, 2015 Posted September 16, 2015 53/39 with 11/28 (11spd) on one bike and 12/25 & 11/23 (10spd) on the other bike's wheels. That extra gear in the reserve (suikerbosrand) is always welcome, more a luxury than necessity. Just ask a few mates who were stuck on 21 or 23 as their biggest rear gear.
cadenceblur Posted September 16, 2015 Posted September 16, 2015 I reckon that standard crank is the issue, but that's just my opinion. I run an 11-23 for training and a 12-25 for races.
V12man Posted September 16, 2015 Posted September 16, 2015 I reckon that standard crank is the issue, but that's just my opinion. I run an 11-23 for training and a 12-25 for races.That 12 is a disadvantage sometimes.... got caught out on the long downhill at the back of smitswinkel.... couldnt spin fast enough to stay in the bunch (53/39).... threw that cassette away...
canadonis Posted September 17, 2015 Posted September 17, 2015 Gears are like condoms.... Better to have it and not use it than to need it and not have it. I have 11- 28 just in case ...

Just wondering for the technical mathematicians out there .... taking a cadence of say 100RPM what would be your maximum speed with a 53*12 vs 53*11?

Thomo Posted September 17, 2015 Posted September 17, 2015 Gone are the days of being frowned up for:- 28t cassettes- compact cranks- 25mm tyres- white bibs sorry, that reamins a no no.! LOL
