The current BB is square taper BB, with ridea chain ring(130BCD) & 5 spider arms. I'm thinking to change it to hallow tech BB. <br />Looking at Shimano 105, not sure what are the things I should look for. <br /><br />Thanks in advance! <br /><br /><br />Anonymoushttps://www.blogger.com/profile/07289453095857584163noreply@blogger.comtag:blogger.com,1999:blog-3932426191875887596.post-91833149470343077642015-12-20T08:52:25.312+08:002015-12-20T08:52:25.312+08:00Changing to a larger chainring will enable a highe...Changing to a larger chainring will enable a higher top speed, but only if you are strong enough to push the top gear.

If I'm not wrong, the...Thanks for the support!<br /><br />If I'm not wrong, the Arc D7 is the 16" curve with a 7 speed derailleur system. This model is not available internationally I think, only in China. There are mainly 2 categories, the international category which you can see from the Dahon website, and the China Domestic models which you can see from the Dahon China website.<br /><br />To upgrade the Arc D7 to 9 speeds, the first thing you need is a new wheelset. The rear hub you currently have can only support 7 speeds. A better and more common rear hub will support 8/9/10 speeds. This will not be cheap.<br /><br />In the event that you do change the wheelset, you will need a 9 speed Shimano rear shifter, 9 speed cassette and 9 speed chain. The RD can technically be used for 9 speeds as I have tried that before, although you cannot expect the performance to be very good.<br /><br />You can get the Driveline bashguard from Taobao.com. Or get from Taiwan bike shops in person. Or try www.thecyclopedia.com.tylstevehttps://www.blogger.com/profile/05202331639299348481noreply@blogger.comtag:blogger.com,1999:blog-3932426191875887596.post-26433657289171322382012-06-13T14:42:23.431+08:002012-06-13T14:42:23.431+08:00Hi Steve... been following ur upgrading blog for s...Hi Steve... been following ur upgrading blog for some time. I must say u r really good at this and also "poisoning" others to an extent. Just kidding... LOL!<br /><br />I have a 16" Dahon Arc D7 sitting at home (courtesy of my Dad bringing back from China). Are all Dahon's D7 models spec-ed the same? Done a couple of PCN rides and have since swapped out the stock brakes and saddle.<br /><br />I am planning to upgrade to 9 speed drivetrain with Dahon Neo RD. You mentioned that ultimately the most important item is the shifter and the RD can handle a switch from 7-9 speed, yes? Can you give some enlightenment here?<br /><br />ps. Also, where did u purchase the Driveline bashguard? Dun think any LBS carries this in SG.Anonymoushttps://www.blogger.com/profile/15995197294895938848noreply@blogger.comtag:blogger.com,1999:blog-3932426191875887596.post-31142539647309080762011-12-07T07:23:17.929+08:002011-12-07T07:23:17.929+08:00If want to go faster, cheapest and best way is to ...If want to go faster, cheapest and best way is to upgrade your legs!<br /><br />But seriously, upgrading BB is not going to help much. getting a bigger chainring helps only if you are already maxing out the highest gear. if not even if got higher gear, but legs not strong enough to push the higher gear also no point.<br /><br />Getting more speeds help if it gives you more gears for better cadence control. Upgrading to more speeds is definitely expensive, need to change many components.<br /><br />Good way to increase speed is to use slim slick tires, or a better wheelset. Getting stiffer cranks such as Shimano Hollowtech II cranksets will help.tylstevehttps://www.blogger.com/profile/05202331639299348481noreply@blogger.comtag:blogger.com,1999:blog-3932426191875887596.post-65755502276254820912011-12-06T23:54:08.333+08:002011-12-06T23:54:08.333+08:00if i'm looking for speed, which 1 should 1 upg...if i'm looking for speed, which 1 should 1 upgrade 1st?<br />1)BB?<br />2)chainring?<br />3)8 speed to 10?<br /><br />which of the 3 is the most costly? and value for $ if i can only afford for one of the 3?明天https://www.blogger.com/profile/17260670501272280226noreply@blogger.com
