jcza Posted January 4, 2018 Share Certainly learned loads here. Max range for 105 derailleur is 37 which translates into the following: Front - 50 big ring and 34 small ring = 16Rear - 11-32 cassette = 21 TOTAL - 37 I'm bringing the CX bike, sure it will be fantastic riding for 165 of 170km. Everyone will suffer up to Die Top. Edited January 4, 2018 by jcza Underachiever and Jewbacca 2 Link to comment Share on other sites More sharing options...
jcza Posted January 4, 2018 Share Thinking of this a bit more. If JCZA could ride Ouberg during the Karoobaix with his Cx bike, then we have nothing to worry about. Mind you, he is as strong as an ox!!! I wake up at night in a cold sweat thinking of Ouberg. Sure it was Eddy that told us it was steep and none of us listened. Last 5km took a hour, and I rode the 1st km and walked 4km. eddy 1 Link to comment Share on other sites More sharing options...

Last 5km took a hour, and I rode the 1st km and walked 4km. It was, and it is not a climb anyone who has ridden walked it will easily forget. I understand only one rider rode the whole way in the Karoobaix and took over an hour out of Darren Lill, recent SA road race champion. Swartberg is but a molehill in comparison. jcza 1 Link to comment Share on other sites More sharing options...

Correct, Charles Keey managed to ride all the way but I must add that Darren was sick. Link to comment Share on other sites More sharing options...
DJR Posted January 4, 2018 Share Except for those 1st set of hairpins from the PA side. Always catches me out!!The hairpins proper are not that steep. The steepest part on the P A side is the half kilometre just below the Droe Waterval. eddy and Underachiever 2 Link to comment Share on other sites More sharing options...
nathrix Posted January 4, 2018 Share Charles Key was the only rider able to ride all the way to the top of Ouberg Pass during the 1st day of Karoobaix against a massive head wind which tried it's utmost best to blow you off the Roggeveld Mountain Range while recording the 2nd all time best Strava time of 1:08:41 for that segment.

milky4130 Posted January 4, 2018 Share Nope. Road shifter not compatible with MTB RD. There are two options, either the Wolftooth goatlink and use the same 105 RD, or a Wolftooth tanpan which is a cam device to alter the shift indexing so that a road shifter works with a MTB RD. I run 1x11, shimano hydraulic shifter with M8000 XT med cage RD with the tanpan and works great. https://www.wolftoothcomponents.com/products/tanpanI bought this TANPAN to work with my XT Clutch RD & 105 10 SPD Shifters, but couldnt get them to work seemelesly & smooth. So i had to put back the 105 RD & remove the TANPAN, but i know the gears\chain jumps\skips when the road gets rof. I'm clueless when it gets to these technical stuff so was hoping there would be at least someone in Cape Town that has experience with fitting the TANPAN successfully.

eddy Posted January 4, 2018 Share Thats not the real story of Ouberg Final 4.8km has 574m at 11% with sections over 20%. Correct. The first bit is gradual and the last brutal. 5.5% average is like standing with one foot on a block of ice and the other in a bucket of boiling water and saying that on average it is 50 degrees and comfortable..... But arguing which is worse is like comparing the Springboks to Bafana. Rather Arguing which is more satisfying when finally conquering it..... jcza and Jewbacca 2 Link to comment Share on other sites More sharing options...

Armand08 Posted January 5, 2018 Share I bought this TANPAN to work with my XT Clutch RD & 105 10 SPD Shifters, but couldnt get them to work seemelesly & smooth.

I'm clueless when it gets to these technical stuff so was hoping there would be at least someone in Cape Town that has experience with fitting the TANPAN successfully.In my case I've got the 11 speed, so maybe there is a difference between the 10 and 11 Tanpan shifting quality. It did need some fine tuning initially. milky4130 1 Link to comment Share on other sites More sharing options...
@BigJohnSwan Posted January 25, 2018 Share Hi All,There is a lot of discussion on what tyres and gear range to use on your weapon of choice for the race. I thought I would share what I am riding with, but please note I am above 100kg and of average fitness. Santa Cruz StigmataKenda 40c Flintridge on the frontVittoria 38C Adventure Trail on the rearAll tubeless, 3 bar pressure at the back 2 bar at the frontWheelset Mavic CrossmaxGroupset Shimano Ultegra 11 speed hydroCompact Crank 50 - 34Wolflink on medium cage Ultegra DerailleurShimano XT 11-40 Cassette I have climbed and descended Swartberg Pass on both sides many times and have had no issue with the cadence at about 6km/hr on the 14% inclines with 34-40. The descents get a little sketchy when the pass in bad condition but it is always manageable. Currently the pass is in very good condition, so I still feel comfortable at 50km/hr + on the straight sections of the descents. With a 50-11 on the flats, you tend to drop those on mountain bike gear ratios with ease. Remember there are many long "slightly down" gradients on the race. This is where the big gear ratios will make all the difference. jcza, DirtyDan, arendoog and 8 others 11 Link to comment Share on other sites More sharing options...

@BigJohnSwan Posted January 29, 2018 Share Thanks for this John. Guess I'm going to find a Wolflink and 11-40 cassette. No Worries, remember that an 11-40 cassette from Shimano is dished inward to take a MTB width axle. Road bike cassettes are mostly flat for a shorter axle. So the 11-40 will not fit on a road specific wheel build. Underachiever 1 Link to comment Share on other sites More sharing options...
