Thanks from the future! Printed myself a nice new knob.

Radiolab is also very interesting. Will check these others out.

Excerpt from the 2012 Jamis catalogue for the DAKAR XC SPORT (which is the only one in there with that type of crank): DRIVETRAIN Shimano Alivio M430 rear & M431 front derailleurs, Alivio M430 Rapidfire SL 9-speed shifters, Shimano Alivio M430 Octalink crankset, 42/32/22, Shimano 11-34 cassette Edit: The BB is probably a ES25

That looks like a Shimano Octalink BB, You will need the BBT-22 from parktool, or similar. You will also need a crank puller to remove the cranks, like the parktool CCP-44.

Lycra with 510's look very strange.

When will you be getting in some more Race Face narrow wide?

Thanks man, that is a good place to start.

I am interested in buying an X-fusion Hilo adjustable seatpost. Before I go the online from the UK route, does anybody know if there is a local agent/importer?

I've never tried it, but I've heard of people using hairspray.

The IS mounts always need an adapter since the holes are at a right angle to what the caliper's needs to be. Post mounts do not need an adapter for 160mm discs since the post holes are in line to what the caliper's needs to be. If you have post mounts at the back, you would not need an adapter. but if you have IS at the back, you would need a 160mm IS to Post mount adapter. If you have IS both at the front and rear, you need to get a 160mm IS to post mount adapter for the rear and you can possibly move the 180mm adapter at the back to the front. If you have post mount rear and back, you can mount the rear caliper directly on the frame, and move the 180mm adapter to the front. If you have post mounts at the rear, and IS at the front, you can mount the rear caliper directly on the posts, and you need to buy a 180mm IS to post mount adapter for the front. And finally, the most common scenario, if you have IS at the back and post mounts at the front, you need to buy both the 160mm IS to post adapter and the 180mm post mount adapter.

Depends on the disk brake mounts on the frame and fork. There are two standards, IS (international standard) and post mount. On the rear you'll typically have IS, and at the front post mounts are more common. Check out this article: http://www.bikeman.c...74mm-post-mount If you have IS mounts you will always need an adapter, but for post mounts you would not need one if you are running a 160mm disc.

Does anyone have experience with these Rapide Ultralight hubs Kiwi sells?

Who can sign this? I don't live near die spruit, not even close, but I do ride there often.

The picture does says crest, but just to the right of the picture there is a dropdown menu to select all the other nice rims.

Just scanned this thread quickly but has anybody mentioned hope hoops? For GBP 260 from wiggle.co.uk and free shipping, you will end up at around R4600 including 14% tax, unless there is import duties involved, which from what I could gather is not applicable to wheels? http://www.wiggle.co.uk/hope-hoops-pro2-evo-mtb-wheelset/ If however you are not interested in hope hubs, it is moot.

There is two ways I have thought about it, either have the strongest hand on the brake with the most stopping power, i.e. front, or the strongest hand always fully on the bar, i.e. back. But I suppose it depends on more than that, i.e. do you always have both hands on the brakes, or does your setup allows one finger braking, etc. Me, I still have them the way they came, too scared too change them.

Have you tried mountainmailorder.co.za for 5.10's? They are bloody expensive there though. I ride with a pair of Impacts, and they are great, grippy as hell.

Thanks for all the helpfull responses so far. Ok, so the ERD should ideally not be measured on a loaded rim, as I did in this case?

I suppose I have nothing to loose, i can just buy the hub, try it out and if it does not work buy other spokes and try again.

There is a couple of threads like this already on this forum, but since it is a topic that deals with a lot of specifics, I hope I will be forgiven for starting a thread like this yet again. I want to replace the Shimano HB-RM65 disc hub on my front wheel with a Hope Pro EVO 2 15mm, since I want to upgrade my shock to a 15mm axle. I measured the ERD of the rim, an Alex Ace 17 that came with the bike, to be approximately 543mm. SInce the current hub and spokes are still on the rim, It was quite a mission getting this. I measured the rim diameter, to be 571mm, subtracted 2 x the height of the rim wall plus the length of the protruding nipple, and added twice the nipple length (12mm). I also subtracte 2mm for I noticed the spokes sit about 1mm deep inside the nipples from the back. I then removed two spokes from either side of the hub, and measered them to be 260mm and 262mm. I measured the shimano hub and got the following dimensions: Right flange ø: 45 Left flange ø: 45 Centre to right flange: 34 Centre to left flange: 22 Spoke hole ø: 2.5 I fed this in to the spoke calculator i found here http://lenni.info/edd/ and by specifying 3 crosses and 32 spokes got these results: Left spoke: 263.4mm Right spoke 264.6mm This is a bit longer than what I measured. I then did the same calculation with the Hope hub that I got from the site database, and got these results: Hope pro 2 evo dimensions: Right flange ø: 54 Left flange ø: 56 Centre to right flange: 33 Centre to left flange: 20 Spoke hole ø: 2.4 Left spoke: 261.6mm Right spoke 263.2mm The spoke brand is "SLE spoke" from this website: http://www.mrrabbit.net/docs/spokeheads/main.html, for what it is worth. Now for my question, unless I messed up the rim diameter measurement, why does the calculated result differs so much from the spokes actually used, and will these spokes be fine with the hope hub. If I look at only the hope results and the measured spoke lengths, it certainly looks like it. Sorry for this long and winding post, I just want to make sure I present all the data.

Hi, I know I am committing some thread necromancy here, but it is probably good to contain information of this nature to a single thread. What is a good place to do a bike fitting in Pietermaritzburg area?

Hi Drongo, I am not exactly sure what size the rotor is, I'll have to go check, but I think it is a Shimano. The bike is a Silverback Saturn, and the spec says it has a Shimano M445 brake set, but no further details.

Thanks for the quick responses, I'll try this advice tonight.

Hi All, I recently bought a new mountain bike. Now what happens is, when I go over rocks and bumps on the road I hear this ringing noise coming from the front wheel area. It used to be only when going quite fast, but it got worse recently. I think it might be the front brake disc banging against something there. It makes the same noise when I knock it with my finger. Has anybody had the same thing happening before? I should probably take it back to the bike shop to get it sorted out, but I just wanted to get some opinions here as well. Thanks.
