Quite hard to find the hubs. Dual chain ring helps a lot in hill climbs. Let's presume that you are in 52T front crank and 14T rear (smallest), that's 74.28 gear inches (GI) in bicycle gearing calculations. Then if you are on the other end, 52T crank and 28T rear, that's 37.14 gear inches (GI) , (the smaller the GI, the easier it is to pedal but covering a shorter distance). If you add another 39T chain ring in front, you get 55.71 gear inches (highest gear) and 27.85 gear inches (lowest gear). so, your full spectrum is from 27.85 GI to 74.28 GI. This is just a small improvement, a 10 GI improvement on lower gear. Presume that you leave the front crank alone an concentrate on the rear and upgrade to 9 speed that starts from 11T to a maximum 34T. Then your spectrum goes from 94.54 GI to 30.58 GI. This gives more improvement on the high gear and a sacrifice of 3 GI from the low gear end. At this stage if you add another 39T chain ring the ratio goes from 94.54 GI to 22.94 GI which is a huge improvement. The problem with 7 speeds is the rear cogs starts from 14T. If you can find 7 speed cogs that starts from 11T (freewheel types) then it is worthwhile to add a dual crank first. As for mountain bikes, they are designed to climb and their GI is from 104 GI to 22.94 GI which is a very wide range! As for my 3 bikes at home they range from 94.54 GI to 17.64 GI for the triple cranks. Here's the formula for GI, maybe yo can make your decision on your own. GI = no. teeth on crank / no. of teeth at the rear X diameter of wheel. Usual 7 speed ratios - 14T to 28T ( I have seen 11T to 28T but this is rare. The brand is Epoch) " 8 speed ratios - 11T to 30T / 12T to 32T " 9 speed ratios - 11T to 32T / 12T to 34T ' 10 speed ratios - 11T to 36T / 12T to 36T As for front dual chain rings - usual is 53/39T or 50/36T for compact cranks triple " " - 52/32/30 T well i believe mine's a 11 - 30t with a front 53t that gives me a 33 - 90 GI if i read the info correctly.. i can cycle up even to air itam dam but i'd like to make it easier for climbing then again i also want the wheel to be smoother too any idea which shld i upgrade first n how much would they cost respectively? assuming i'm just going for the decent-enough entry level components the reason y i wanna get a trigger shifter first is bcuz i wanna change the stock grip to one with bar end, also because trigger feels nicer la so i'm guessing u'd either recommend to stick to 7 speed n add a dual chainring first OR change the wheelset plus upgrade to 9/10 speed..?

QUOTE(SonnyCooL @ Oct 10 2013, 02:30 PM) Internal 11 speed is cost a bomb here some one quoted me rm 2.2k for shimano internal 11 speed, so i go for internal 8 speed which cost half old doesn't means poor, i still have my 20+ year old racing bike with first generation Shimano 105 component i thought it was an el cheapo bike that i wanted to discard already, until i notice the carbon design n all the deore xt/lx component luckily i din sell it off to the recycling center

This will ease your ride a lot and also tackle more hilly roads. Later can go for the dual or triple chain rings. hmm okay la, wheelset n cassette it is first then! how much r we looking at first though? wheelset itself shld be a lot of money d right?

PM robyn, he's selling it and also there's another extra pair too. They are going for Lite Pros. okok noted, thanks

I think the components can accept a bit of tolerances. Only in the 10 and 11 speed that the adjustments are so minute they give problems. So, you are quite safe in using the Shimano shifters on any RDs and FDs. is it due to the 2:1 shimano n sram 1:1 pull ratio issue or smthg else altogether? well i just wanna change the gripshift to trigger, that's all

I have to order from China though. Takes 3 weeks time. The Litepro seatpost plus the wheelset plus detachable pedals should come to about RM600 plus minus RM100. With that I can throw in a 9 speed upgrade with SRAM Attack gripshifters for another RM150 (all inclusive, shifter, Neos 3.0 RD and cassette but you need to have the wheelset to accommodate). All are from the Tern P9s who have modded up. i want eh! soon laa.. throw in a double compact as well can ah? n any tentative date n time for ur penang ride? i did n went n check out the bike trail at pulau betong some time early this year but nvr go all the way cuz i was literary alone in the entire trail not knowing where it leads to

That's another RM550 to RM600. If you want a double or triple chainring cranks, you can't use Neos derailleurs. You have to go for Shimano Altus or X4 RDs depending on your shifters. The Neos have super short cages, that's why when they do 27 speeds or 24 speeds they use a 3 geared internal hub together with the conventional RDs and cassette. When they started using Neos for 18 speed setup like Dr.Hon Dash 2013 and Dr. Hon Visc P18, the Neos failed big time. They still didn't change back to Shimanos but altered the cage shape to prevent the chain from getting jam and pulled the whole RD apart. Still, the RDs are not really smooth and till today, if you back pedal , the chain get stuck. Try it! I will be riding in Penang on the 9th November and staying the night in Balik Pulau before continuing the next day. Let's explore the Gertak Sanggul to Pulau Betong together. It's good for you too, right? hmm.. more decisions to make! isk guess i'll take it step by step to appreciate the different quality level as i upgrade first will be the wheelset! anyway u're gonna cycle in the mrng right? i might have to work thru weekends but if the dates r confirmed i'll try to take a day off laa..
