  1. I love my spark. Really usefull to totally lock out or open up or inbetween witout moving my hand from the hande bar
  2. Hi. Is there and when a next imana wild ride. I cant open their website its not tablet friendly
  3. OK tried the high position. I don't like it - you sit so much more forward on your handlebar that my hands hurt. Handling is twitchy and you really have to lean back on downhill sections. And I fell within 5 minutes on a wet Groenkloof which also did not help with the confidence of the new setting. I went back to low - mostly because of the pressure on the hands- the increased handling was not worth the conns.
  4. Thanx for the feedback guys. Ill try it the week-end.
  5. Have any of you adjusted the BB height with the shock mount chip in the linkage?What did it change in feel and handling?
  6. This was my first Lost City 60 km. I never got lost although I was alone for long periods so I was happy with the marchalls and the routes. I thought that walk up the hill seriously sucked and I was very worried about the downhill part - I wonder how many guys got badly hurt? Its simply unridable for mere mortals. This was for a good cause so Ill give it my vote but I would expect for next year the following changes: Take a time of the year when the veld is more scenic Cut out the hill walk for goodness sake Have more track in the reserve at least that was fun
  7. Results page MTB - anyone can help?
  8. I have the Spark Pro. I changed the seat post - biggest weight saving, I changed the handlebar to carbon. I changed the rims to American Classic (only because I had them). The rest is sweet
  9. How much do these weight? At least they don't look too ugly.
  10. I guess there comes a time when function overrides lookes
  11. Can we get some views on there saddles from someone who use it? Do you feel in anyway impeded with technical riding?
  12. A lof of the gels contain caffeine - but does this not push up your HR? And is a lower HR not better when racing?
  13. I bombed one tire, the other one not - both had balls , both tires were new...maybe that's it? So maybe to hijack my own topic - how many stans cups do you put in your 29er tire?
  14. I've changed a few tubeless tires and was amazed to see the size of the silicone ball (not exactly round) inside each time. Some of the tires I only changed like 4 weeks after the original stans dosage. What cause this?
  15. So there's online calculators and they show some....but not great improvements around a half marathon course. I think the value in loosing weight is that on hills you don't hit lactate threshold so soon.... But anyway - I'm asking guys who's managed to drop this amount of weight AT THE SAME FITNESS LEVEL...what % could one expect to be faster over a 50 kim track, say 1,000 meter climbing.
  16. I have a 26er, and 2 x 29ers....now for a in-be-tweener! Awesome!!
  17. I have Rocket Rons back, Racing Ralphs front on bike 1. One bike 2 I have Racing Ralph upfront and Icons back. I had the Rocket Rons front as well and the grip is better. I think the main question is the skill level of the cyclist - Racing Ralphs upfront is probably not ideal for a newbie - make the first new front tyre one with lots of grip.
  18. O dear there goes my whole attempt to restore credibility to the bike. Luckily I don't do 5 day stage races
  19. Did you replace the handlebar with a 680 9 degree bend?
  20. I’ve read a lot of mixed reports on the Scott Sparc pro, some of them really not flattering. It’s especially the rear shock which seems to get the grunt of the disapproval. But I just got a Spark Pro and thinks it’s great, so here is a report by someone who actually owns one (2 x 36 km N Farms + 1 x 25 km GroenKloof ride). Am I qualified to review bikes? I’m a middle aged committed week-end warrior who has been MTBing for about 18 months. I’ve never been on a 90 K Specialised so no I don’t know what I’m missing, I did not come through the 26er ranks so I can’t really compare with that, I’ve only owned one other bike – also a 29er – so my spread of opinions are limited, I’m not a pro and I’m not particular fast. So guess what? I probably represent 75% of the Mtb riders in South Africa so maybe they are interested in an opinion. My other bike is a Trek Hi Fi Plus 29er, so before you cry that’s entry level consider that I’ve upgraded the wheels, tyres, stem, saddle, seatpost, handlebar and shock (to a RP23 with Kashima bling),Its 13 kg and not a bad bike. Scott Sparc Pro: Lets start with the sales pitch: So this bike has a 3 position switch which is handled from the handlebar (easy peasy) and you can have 3 settings. (1) The front shock is quite hard and the rear shock is totally locked. Yep – you now have a HT, congratulations. This configuration is made for smooth-ish climbs and flats. I use it a lot as you have no bop and have maximal power transfer to the wheels. You can even stand out the bike if you want. Yes – you can feel the difference (2) The front shock is more plush and the rear shock opens up a bit, but still firm. This is like riding a RP23 with the toggle to the right. This configuration is where it’s rocky, rutty or you are moving fast over unknown terrain (3) Both front and rear shock is totally open. Like riding a RP23 with the toggle to the left. Clearly this is for downhills and as it’s so simple to flip the switch to get here, why not use it? The ride: So you can change the suspension with the flip of a switch and that adds a great dimension to the ride as you can optimise your bike given the 10 meter of dirt in front of you. But that means that you must use it – if you take a hard hit whilst you have the shocks locked out you will break your bike and risk falling as you now have less traction. So the marketing pitch actually works…and very well. In single track the bike amazed me. So much faster than what I’m used too – you can just rip. The bike turns tight and turns in properly. This is probably an even bigger feature than the suspension system. I felt that I could sit down longer and did not have to stand as quickly to get better handling. Downhill - Its very accurate – you wheel goes where you aim and the bike splendidly tracks direction – it takes no effort to keep it on route. When you hit the brakes hard the back does come loose so it required more still than what I’m used to. I think my Trek rolled faster downhill – maybe the RP23 soaked up hits a bit easier, but I felt more comfortable on the Scott because it would stick where I aimed, until you hit the brakes and you have no Trek APS to assist. Climbing – I believe I can climb more efficient. Technical up and down – The balance is great, I did not have to think of moving my weight back or concentrating on weight distribution, it’s just so easy and feels natural. The feel of the bike is more Racing than Cruiser. I find myself huffing and puffing more as I keep on pushing to go faster. With this bike you need to pace yourself – it will burn you out if you don’t watch your pace. The components: The gears shift like silk, no issues, no delays, no chain drops – simply delicious and what one would expect for this kind of money. Brakes brake. I don’t know how one is better than another… The 2 x 10 will still take me a while to get used too…My issues are not that I felt that did not have enough gears…more to do with the choice of the larger blade, or the smaller one. There is no middle blade so you gotta pick larger or smaller. The handlebar is wide and contributes to the smooth handling through windy single-track. I replaced it with a 660 mm 5 degrees handlebar but my hands got sore and I feel I lost a little bit of the handling, so I’m going back to the original configuration, Pro has a carbon version which I will try and get. The tyres are Rocket Rons (tubeless) which are simply great – fast rolling and confidence inspiring. I swapped out the front tyre with a Racing Ralph and the Rocket Ron definitely feels a bit more confidant. These tyres compliment and contribute towards the great feel of the bike. The saddle is lekker. The seatpost is nonsense. Its heavy and is a set-back seatpost on an aggressively setback frame. I can’t get the saddle moved forward enough. Best replace this with a light seatpost with zero set-back. The wheels are OK but a tad heavy. I’m swapping them out for my ‘old’ American Classics which will yield about 400 g weight saving. I really can’t fault the suspension, for all the criticism I think the DT Swiss Nude 2 shock works very well. I think the bike will come in at 11 kg with XT Deore pedals, slime, bottle cage. Right now its 11.4 kg but there are still upgrades to be done. It’s a Carbon frame so if you win the lotto you can really get it light with upgrades. In conclusion I did my best average speed on my standard 36 km route on my first go on it, and I did not try to beat any records. Its not a cheap bike but I think it lives up to the marketing type. Its still very good value for money (in the cycling world). I think it’s great and does not deserve the bad rep some people posting on it (who never tried one). Swap out the wheels, handlebar and seatpost and surely this must compare with other 60 K bikes? It’s nimble and efficient. The only downside I can think off is that you now have a bike that you can turn into a HT for half the ride, your bum certainly feels the extra impact. And of course – you are going to battle to find one as the last stock for 2012 are drying up… Robo
