Dubber88 Posted February 10, 2012 Posted February 10, 2012 Good day Hubbers, Quick question. Which one of these two tire combo's would you suggest for the Sabie Classic? - Rocket Ron 2.25 rear @ 585g , Racing Ralph 2.25 front @ 520g. Evolution tripple compound. OR - Ikon 2.2 3C rear @ 580g , Aspen foldable 2.1 front @ 585g. I own both sets. In my opinion the Maxxis tyres would have less roling resistance to help for all the climbing, whilst the Schwalbe's have allot more volume which will help allot with a more comfy ride at the right pressures. Any suggestions/comments... Regards,Dub
kosmonooit Posted February 12, 2012 Posted February 12, 2012 Most of the route is hard packed gravel road, and depends on the weather how slippery it gets I am running CWC Special Maxxis 2.1 Crossmark 2.1 on the rear, have a Knobly Nic on the front - worth keeping the back tyre a bit tight and having something chunkier on the front for grip in turns and down hill, but that's me. I have a Maxxis Ignitor 2.1 in the post which I might fit on the front.
Goodbadugly Posted February 12, 2012 Posted February 12, 2012 I have done quite a few Sabies. I ride Maxxis. Crossmark/Monorail UST.Rolling resistance? I have seen myself also falling for these marketing ploys. I have also read all the links to guys (in Germany) testing tires for rolling resistance and coming to the conclusion that Conti Race king Supersonic and Schwalbe Evo RR (German brands) offer the lowest rolling resistance. I am not that convinced any more. It seems that the rolling resistance gets less when I am fit and gets more after the December holidays.Also check out the real width of the tire CASING with your vernier. You might find that the RR is not a real 2.25 tire. They measure the knobs.What are you riding at the moment?Just ride and enjoy.Flame guard ON.
goya-goya Posted February 12, 2012 Posted February 12, 2012 rolling resistance is a serious issue in cycling... If you wanna get Technical:it all depends on the terrain, your strengths and weaknesses, tyre pressure weight if your wheels and then your actual tread... All of these play a role - pun intended - in rolling resistance... the best way to do check this out : put on a tyre. set up the pressure. ride down a hill... no pedaling... try as much as possible to start from dead stand still... got to the top again... change tyre pressure... repeat... change tyres and repeat... riding in a straight line most tyres compare fairly similarly... its when you engage the side knobbs when the rolling resistance is at its greatest... hence the race king being so good... but if you are not technically proficient you will see your ass! I would put the rocket ron on the front and the racing Ralph on the back.
Dubber88 Posted February 12, 2012 Author Posted February 12, 2012 This will be my second Sabie 73km, and rode the first time with a Crossmark - Monorail combo on a 26" FS. Raced with a Race King Monorail combo last year, and was very happy. Unfortunately I don't have a Race King 2.2 as they are quite rare. It's definitely not a marketing ploy, as the tire with the smaller gaps will not let the tire move too much in a upwards and downwards fashion opposed to a very aggressive tire, when rolling on a smooth surface. The same as fitting BF Goodrich tires and seeing your consumption decreasing, opposed to high terrain tires. I have both sets and still need to test out what rolls faster going off road. Also , a high volume tire at lower pressure is more efficient on an uneven uphill, irrespective of the tread, as the tire rolls trough the obstacle opposed to over it. But, would like to hear what the hubbers think

goya-goya Posted February 12, 2012 Posted February 12, 2012 I did Sabi last year... not a wet spot in sight... actually the only wet section was a 10 meter section at the top of the "glass slide" climb... bet you this year it will be a mudfest! I hated Sabi because I was under the impression there was singletrack-a-plenty... NOT! only 300m!! Well maybe not hated... just disappointed... I fell on the first downhill at about 50km/h not too much damage... Good luck!... I am sure it will be awesum

WIthout a doubt a Rocket Ron Racing Ralph combo will be a cleaner(tires) and safer option.

Cycling Addict Posted February 13, 2012 Posted February 13, 2012 Not to hi-jack the thread but which would be preferable - 26'' FS or 29'' HT?
Dubber88 Posted February 13, 2012 Author Posted February 13, 2012 Not to hi-jack the thread but which would be preferable - 26'' FS or 29'' HT? FS is allot more comfortable for your back. HT's climbs a little bit faster on non technical terrain and flats but is hard on your body.
