20" fixed wheel build - any component recommendations / advice?
I posted a thread over in folding bikes but thought I'd give it a shot over here as well:
I've been enjoying my Tern Link Uno folding bike for around-town use as well as train commuting between DC/NoVA and Baltimore for about a year now.
Being a fixed gear rider otherwise, my goal was to eventually convert it to that, as the dropouts are horizontal and perfectly spaced at 120mm.
The fact that the Tern's coaster hub cone keeps coming loose in pretty short intervals finally has me jump into action.
I visited a local bike shop where I planned to have the wheel built, but, besides the advice to use a low flange hub, I haven't gotten much further.
My current Tern stock rim is a little over 1" wide has a 1.6" wide tire mounted, so I plan on keeping it in that ballpark.
Any recommendations on rim, hub and spoke choices would be much appreciated, also any existing information on acquiring a complete wheel.
Not many 20" fixed wheels out there so best bet is a wheel build.
Sun CR-18 rim
All City Track Hubs
Outside of campy track and DA track(Major $$$ both of those), you're not going to find a decent hub with a low flange so high flange is probably going to be your best bet.
So I'd look at the all city track hub or the all city new sheriff hub.
As to spokes: straight gauge or double butted and would you be doing two or 3 cross?
I actually have/ride a fixed gear bike with 20" wheels, there are a couple of pics of it floating around here if you are interested to see it.
My wheels are built with inexpensive Joytech hi-flange hubs, but in reality with such small wheels & short spokes, there are very little stiffness or strength worries to using lo-flange hubs. Keep in mind that there are actually several different 20" rim sizes so if you are going for a completely new wheel, be careful to get the right one. With BMX, folders, recumbents, just about all major (& many specialty) rim manufacturers offer 20" so you have tons of choices.
But the fact is, unless there is a problem with your rim- since your bike has 120mm rear spacing, it sounds like your simplest option is to simply have the shop rebuild it with any decent new sealed bearing track hub (i.e. Formula) & basic spokes.
Frankly, it turns out I just talked to the wrong bike shop at first.
I'm currently having a wheel built up (at a shop in Baltimore that I like and which worked up a bunch of options for me) with an 28-hole White Industries hub (I do like their splined cogs), laced to the existing rim with straight gauge spokes.
I also decided to take a slightly deeper plunge and get an All-City 612 crankset with 46T chainring, which allows me to dial the cog size all the way down to 14T.
Needless to say, I'm looking forward to putting it all together.
