NWT – handlebar update

There is a bit of obsession going on with my NWT over the recent weeks. I guess I have not put much thought on my earlier bikes and I just ride them without worrying about prettying them up or focussing on minor upgrades. Guess this is probably a phase and I will ride (no pun intended) through it as it passes.

One of the things that I found to be a bit of an annoyance was the location of the brake levers. I guess I am pretty happy with the gear shifters but the levers seemed to get in the way of where I found my hands comfortable, i.e. near the curve up front. So I made a mental note to push the levers forward. That means the the levers are going to be in partly in the bend and the levers may flare out.

I pushed them forward a bit and indeed the levers stick out a little. Not something that will bother me with my long fingers but people with small hands may find it a bit difficult. But then they may be comfortable keeping the  levers closer too. Like I mentioned, the trekking bars provide a variety of options and is fairly customizable. A couple of rides will be able to give me a sense of the position of the levers.

Anyhow, I felt good about the positioning and took some time to wrap the bars with the cloth bar tape I picked up from velo orange. Though it looks a little odd, I kind of like the two tone color scheme. I was planning to wrap over with a leather tape but I will wait to do that until I am comfortable with the positioning of the lever.

The positioning of the bell near the brake lever was pretty much annoying and I moved the bell to a place near the stem. I have to move my hands to get to the bell, but then I dont intend to use it to annoy people in busy areas. It is more of a device to communicate with my riding buddy over a short distance. It is pretty nice tool for that.

Finally, I gave a bit of boost to my LHT. I currently have a ESGE double kickstand and since the LHT does not have a kickstand plate, I was living with the annoyance of frequently tightening the stand. Furthermore, my stand came with a flat bold instead of a chamfered one. I picked up a chamfered bolt from Clever cycles (they were nice to give it to me for free!) when I was in PDX. I decided it was time to change and some of the leftover bartape came in handy. I picked up this tip from the Rivendell site and without over-tightening the bolt, the stand seems nicely fixed in place.

A good way to spend some time in the weekend don’t you agree?

NWT test ride – Kota Tinggi Loop

You might have observed in the past few posts, there were a bunch of equipment upgrades on my bikes. Some of them well worth it, some probably vain. There seems to be missing an essential component, that of riding the bike. Heh, It is about time I really road tested the NWT.

Al, requested for pictures of the complete bike and here they go.

First up, a 100 Km loop to Kota Tinggi. It was almost impromptu ride, my brother pushed me to join him and I figured it is a good excuse to take the NWT on a shakedown. You know bikes take a bit to settle down. Cables will stretch, tires will roll into place, brakes will wear in etc… I had a few things to check out too, like how do my panniers fit the rear rack, will I have heel strike, will my setup with skating wheels work fine with the panniers, how will the dual drive hold up over long distances etc…

I realized after the initial short rides, the shifters were a bit tricky to reach, so the first adjustments were made (I have not put on bar tape yet expecting more adjustments in the coming days). I swapped my B17 with the B67 from the Surly and the bike was ready for the road test. The bigger question was whether I was ready :)

For those who do not know about SE Asia, we do not have regular seasons, the only thing regular is the intense sun, high humidity and thunderstorms and usually they decide to mix and match combinations as the day progresses.

We started off about 0830 in pretty much high sun and the only thing I could look forward to was some cheap / great food in JB and if lucky, some showers in the mid day. Luck did not hold out for us and we were served with intense heat and near 100% humidity throughout the ride. As it is with riding out through the causeway into Johor Bahru, heavy traffic is the norm until you cross Kota Tinggi. So an out and back loop means that we are practically in heavy traffic throughout the ride. Added to it was the fact that the highway 3 was being extended and all trees have disappeared. Shade was scarce.

Well let me say that it was a very difficult metric century. We ran through a few litres of water and at least a litre of gatorade (each) before we decided to turn back. At the halfway point, we stopped by a street side coconut vendor (Thank god they are willing to brave the heat to quench the thirst of travelers) and gulped down a couple of coconuts before turning back.

It was a good decision in the end as my brother was pretty dehydrated and exhausted when we reached JB. The ride route as follows:

So how did the bike hold up in this ride. Well, excellently. The  setup is a bit more upright and the B67 was a good choice, no sore butt or shoulder. The trekking bars were great. There were indeed many comfortable positions I could use, a worthy choice again. I do not like the position of the levers, I may push them forward a bit but given the curve on the bar, the levers might flare out a little. I will have to try the setup. I will most definitely move the bell to some place near the stem. The bell is a great idea to communicate with my brother over short distances. Ding Ding and we stop to check each other out.

I liked the friction shifters. Infinitely better than the twist shifters. The Tikit my brother was riding had a very tight twist shifter and the rear dee was also out of alignment. He had a terrible time shifting. Not so for me, heh. If I don’t shift smooth at first, I just need to feather the shifter and I am sailing along smoothly

The Dual Drive was a revelation. I need to probably write separately about the dual drive. It deserves honorable mention. But let me say a few words, Shifting was precise and smooth. I did have to use a trigger shifter for that and with a quick flick, I go from pounding on the pedals to tootling with a whistle on my lips.  The best part was that I could stick to any of the 3 gears and still choose to use the entire cassette. That means less fiddling with the gears. If you have been riding with front deraiullers (which most of us are), this is really neat. And the gear range is very nice. Rolling hills, well, bring it on I say now.Al e-mailed me once to caution me about some of the quirks of the dual drive. It has not reared its ugly head till now and I will wait for them to surface. For now, dual drive is really worth it if you are considering it for your bike.

The only minor issue I had was the chain slip when I switched gears too quickly (on the cassette not the dual drive). That is because of the odd angle the chain has to take when in the extreme gears. A chain guide should patch it, but I am in no hurry for that.

Overall, the bike worked like a charm, an intense metric century in trying conditions is the best way to check out a bike I guess and the NWT passed the test in flying colors. Thank you Bike Friday!

NWT upgrades – Drive train

Here are some upgrades I have done on the NWT. It took me a while to gather required components and it was speedily assembled by the very competent folks at TR bikes.

Porn first, story follows:

SRAM dual drive II rear hub: I got this from the local Dahon dealer. I have been thinking about getting a bike with dual drive for a long while now (since a couple of years back when I first saw the Dahon speed TR). My brother wanted to setup a similar drivetrain on his tikit but to keep things even simpler, opted for the Alfine 8 speed instead.  I had a nice ride around and I should say the Dual drive is pretty cool. The gear range is awesome, very very low gearing and a very reasonable top end too. I am not too fond of high speed riding and the current gearing seems spot on.

I hunted around on the internet for a 32 hole dual drive but did not find a suitable hub. But as it happens, we search for things all over without realizing things are probably right under our noses. When I eventually enquired with the friendly fellers at speed matrix, I found that they had a built 20″ wheel with the hub ready to be used. I pounced on it and am glad I did. The ride is smooth, the gear shift within the hub is very smooth and silent. And though it does not sound to be a big deal, the ability to switch gears while stationery is really nice to have.

A+ for the hubs (until I get a puncture I suppose). Actually removing the click box is easy, I just need to carry a spanner / wrench to remove the wheels. Not a big deal at all.

Nitto B825 multi position bar: Flat bars are nice and minimalist and good for zipping around town. A folding bike is primarily designed for that and I respect the choice made by manufacturers. The nice thing about the NWT is the fact that they do not restrict you to stick with one type of bar. Since they take standard stems, I have a choice of any bar I want. I was thinking about getting a Moustache bar or my favorite Midge bar. It just happened that TR bikes decided to put their trekking bars on sale (and they were Nitto too). Well it was a bar I have been thinking of checking out and figured this is as good an opportunity as any to swap my bars. So on they went. The only trouble with the multi position bars is that they have multiple comfortable positions (doh) for your hand. This means that there are numerous choices on where to install brake and shift levers.

The configuration above shows what I decided for a first design. Brake levers go on the sides (pretty comfy hand position) and the shift levers are going on the ends, away from the brake but not a bad place for them. On the left is the shifter for the Dual Drive hub and on the right is the sunrace friction shifter for the 8-speed cassette. The sunrace shifters are a bit twitchy but I got used to them in under 3 minutes. After a 10 km ride, I think I would push the brakelevers a bit further up and once I am comfortable, will put on the bartapes etc..

MKS Grip King pedals: I picked them up at clever cycles when I was visiting portland a couple of months back. What can I say, they offer good grip even with sandals on and a large surface to rest the foot. I have no complaints.

Bike Friday Folding rear rack: I picked these up while taking delivery of my NWT and they definitely look very well made. The finish is nice and dare I say you can mistake them for a tubus. The nice thing about the rack is that the joints are supported by screws. This allows for folding the rack and add on some roller blade wheels for pushing the bike when folded. But I am also afraid after a while of carrying load, the threads may strip. Not an immediate concern but it is at the back of my mind anyway.

I bought a bunch of cheap skating wheels and put them up (I could not find the wheels in black). The wheels with bearings etc cost less than 20 sgd. They roll smoothly but is a solution to push the bike to a corner without damaging the rack and not for pushing around town.

So that’s the upgrade till now. There is a one more thing and I will update once it is complete :) . As it is the bike is all ready to rock and roll.
