kaybs41282 Posted May 1, 2011 Report Share Posted May 1, 2011 Hey all, I'm about to slap a grind on my rear wheel for the first time, is it worth doing the front too? Does anyone else do this? I understand there will be zero modulation but is this a big problem? Cheers peeps Chris Quote Link to comment Share on other sites More sharing options...

AndrewEH1 Posted May 2, 2011 Report Share Posted May 2, 2011 It all depends on how you ride. If you want very good bite and hold on the front wheel you should pop a harsh grind on. If, however, you want a bit of modulation either leave the rim as it is or put a light grind on which will reduce modulation slightly but help in wet or muddy conditions.

PaRtZ Posted May 2, 2011 Report Share Posted May 2, 2011 What front brake do you have? And pads? Some pads work best on smooth rims too, so a grinded rim will shred the pad if used excessively! As said above answers your question. Don't forget if your riding downhill anywhere, you'll either have to skid the back tyre and wear that down, brake with the front (but you'll have no pads left at the bottom), or walk. Or go flying down it brakeless....... Quote Link to comment Share on other sites More sharing options...
kaybs41282 Posted May 2, 2011 Author Report Share Posted May 2, 2011 Cheers chaps just running hs33s at the moment with black pads up front but looking at pads for medium to light grinds... Any recommendations? Has anyone seen those magura red pads with a Cnc backing on eBay? Just wondering if they'd be suitable? Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted May 2, 2011 Report Share Posted May 2, 2011 if you mean the koolstops, no Have a look through the last few pages of recent pad reviews. They give good ideas on the recent pads that people have used, how theyve used it, and what grinds theyve used them on. Usually I suggest ebay for everything, but for consumables like pads, go through tarty bikes. You will pay about £30 but they are worth the money... I found running blacks on a grind made no difference at all but you need to choose what braking you want as made above ^^. If you want the modulation, you may as well stick with the blacks on a smooth rim Quote Link to comment Share on other sites More sharing options...
kaybs41282 Posted May 2, 2011 Author Report Share Posted May 2, 2011 Where is modulation an advantage? If I don't have any will it hamper me when learning certain things? Quote Link to comment Share on other sites More sharing options...
Carlperkins Posted May 2, 2011 Report Share Posted May 2, 2011 ive recently ground both my rims, i ground the rear and running tnn lgm's then did the front and put on heatsink yellows. when im going down hill fast, i do the old foot on the back tyre job. i wouldn't have thought it would have a massive affect on the tyre, maybe over a year it will but oh well.

kaybs41282 Posted May 2, 2011 Author Report Share Posted May 2, 2011 Cheers Carl... I know this is slightly off topic but why different pads on different wheels? Also, is there much difference when you use pads with CNC backings... What's the advantage? Quote Link to comment Share on other sites More sharing options...
Sam T Posted May 2, 2011 Report Share Posted May 2, 2011 Also, is there much difference when you use pads with CNC backings... What's the advantage? It makes your brake alot stiffer. Instead of the pad hitting the rim and the pad backing flexing it pushes the pad into the rim with minimal flex at all giving you a better brake. It also makes a slight difference on the feel of the brake on the lever. One tip though - Make sure your pad is hitting the rim exactly square becuase as there is no flex in the backing your pads will wear at a angle very easily.. If you are on about the Red CNC pads that are from Poland or somewhere then they have had some good reviews. You can pick soft or hard compound when ordering - Soft for smooth rims and the hard compound for ground rims. I'm currently running both grinds front and rear with Heatsinks on the back and Koxx Reds on the front. I ground the rim originally with a harsh grind and put a new set of Heatsink Yellows on. The brake was seriously crazy. It locked up instantly, giving you absolutely NO modulation. I found this hard to control the bike at times, with the power ever beng ON or OFF. I sanded the rim down and put these pads on and it is much better. Light grind and a decent set of pads is wicked! If your looking for a cheap decent set of pads then i can Recommend the Onza Lime ( green ) or citrus ( yellow ). Although, i would also recommend a seriously LIGHT grind as these pads wear down very quickly. Hope some of this will help you! Sam Quote Link to comment Share on other sites More sharing options...

Luke Rainbird Posted May 5, 2011 Report Share Posted May 5, 2011 when im going down hill fast, i do the old foot on the back tyre job. i wouldn't have thought it would have a massive affect on the tyre, maybe over a year it will but oh well. Your shoe, on the other hand, will be annihilated rather swiftly... 1 Quote Link to comment Share on other sites More sharing options...

Yeah I run these on the front vee, with a very light grind and I simply can't fault them. Got the hard compound. They've lasted me ages too.

You risk snapping your crossover doing that. Unless you have a braided one, in which case, you don't. Quote Link to comment Share on other sites More sharing options...

Unless you have a braided one, in which case, you don't. nah i have a booster, but i dont touch my foot on the booster anyway, no need. i usually drag the side of my shoe on the side of the tyre, effective. not wearing my shoes out or the tyre at the moment, does mark my shoe though. and back to the original topic, i ground both rims, run tnn lgm's on the back and heatsink yellows up front. will soon be running tnn lgms on front and back, so ill have a set of pretty much new heatsinks for sale soon probably.
