Hope you don't mind if I put several (possibly daft) singlespeed questions in one thread please?
I'm just about to take delivery of some new wheels - Hope Pro II Trials / SS rear hub and they're going on my vertical dropout Rock Lobster Team Ti.
That's currently magic geared with a 34T chainring and a 17T screw on sprocket, so I can't re-use the latter on the new wheels. I could get a 17T rear cog and put that on, and run the existing chain and chainring, or I do have a choice of chain ring / cog options in the parts bin. The 2:1 ration does seem to suit me around here though.
1: I'm using a KMC chain and like the ease of how it joins. It's a 3/32ths width, but can I run an 1/8th" width on a regular chainring without any problems?
2: Do chains stretch to a point, like gear cables do, and then stop stretching or will they continue to wear and therefore stretch? I think I know the answer but it would be good to hear.
3: Do 1/8th" chains stretch any less than 3/32ths" or is it much of a muchness? It's just that if I can get a chain that resists stretching I can keep magic gearing the bike. I just worry that the status quo will not remain as the bits get older and more worn - in fact it's sagging just a touch anyway now, which can't be good for it.
4: I've got external bottom brackets on all my bikes, but there must be something better - is it worth me looking at a Middleburn singlespeed crank with a square taper BB? I've just about had my fill of the short lifespan of these BBs, but so saying...
...I'm still waiting on a solution to be available on the Eccentric Bottom Bracket in a regular shell vein. The American Forward Components one is currently out of stock as he's not got bits for it that he needs, and I'm waiting on a STW advertiser bike shop to eventually do the deal with Excentriker for theirs - again, I think they have stock problems in Germany. Either way, they're over £100 each anyway, so I could do without the expense...
OK - you can go now! Thanks for reading this far. Stop yawning at the back.
