Bike Stuff

Mechanical experience I've been messing around mechanically with bikes for decades.  I learned the basics in childhood doing all the basic tuning and repair activities. But it is only in recent years that I've started to take on the full spectrum of work. Recently, I've started building bikes from the frame up ( Litespeed Road ,  Litespeed Gravel , Waterford ) and fully overhauling  old bikes with various generations of technology. Doing this brought in new skills like replacing headsets, working press-fit bottom brackets and hub bearings, hydraulics, and more such that there isn't much I don't feel comfortable doing. But wheelbuilding is scary But there was one major component build that remained scary voodoo to me: Wheelbuilding. I'd been able to true a wheel without screwing it up since I was a kid. But the idea of starting with a hub, a rim, a stack of spokes and a pile of nipples made me very uncomfortable and I avoided it. I avoided it even when the rear ...

So, there has been a fair amount of chatter in the last year+ about the new electronic shifting gravel groupsets from China.  LTWOO got to market first with the eGR and you can read my writeup of installing that here . But more recently Wheeltop came out with their equivalent GeX system ( Installation writeup here ). Initial pricing on both was almost too good to pass up as an experiment and I did so. Current pricing is still quite competitive vs even the lowest end electronic shifting from SRAM or Shimano but not the 'no brainer' it was at first. Highlights of these systems: Both 'groupsets' are really just 1x mini groups. They both include: Rear Derailleur Brifters Brake calipers Charge cable (use your own USB brick) For a full groupset, you will still need to provide: Crankset/chainrings (1x only with GeX and eGR. Both have road 2x options) Chain Cassette options: Wheeltop GeX 3-14 cogs, 10-52 teeth LTWOO eGR 10-12 cogs, 11-46 teeth officially. However, I've run ...

I've already had experience with the first of the new, value-priced electronic groupsets from China in LTWOO eGR. You can read about that experience here , but in summary it's pretty good but wasn't perfect for my application for two main reasons It expects to stash the battery inside the frame and have a wire run out to the derailleur. Unfortunately, my V1 Cutthroat isn't set up that way and I had to strap it to a bottle cage in a less-than-pretty way Officially it only supports up to a 46t cassette and I run a 50t. It does actually work, but it's a little cranky about it in setup and operations. But along comes the Wheeltop GeX solution. Same idea from a company that has been making components for others for many years and MTB electronics for a couple of them. It promised to address my issues in that it uses a battery attached to the rear derailleur directly and officially supports 51t cassettes. Reports are the...

With the original  Shimano 105 5500 9 speed triple Aluminum-framed, 105 triple road bike  Klein was one of the original makers of aluminum frames using 'oversized' lightweight tubing. Today the proportions look totally normal. But it was avant guard 20+ years ago. In 2002, I'd been riding the Bianchi Nuovo Racing as my road bike but moving down to Menlo Park, road biking became more important than mountain biking and it was time for an upgrade. In early 2003, I found this 2002 model on closeout. In some ways, it was better than the newer ones because it was the last of the Kleins to get the trademark cool paint job. Trek had purchased Klein a few years earlier and they were about to start painting them 'normally' like other Treks.  What is cool about this paint job? It's not just "Plum Crazy" purple (and purple is kinda cool all by itself), but it is a semi-translucent paint with metallic flecks and is color-changing. Huh? Color-changing? Yeah, dependi...

Backstory:  A fun little project I finally got rolling last night. I picked up a 1986 'Trek 700 Tri Series' from the local bike exchange in an 'as is' condition. (Not the kind of bike to give someone as transportation, not exotic enough to be worth restoring to flip, so sell at a bargain). FWIW, getting to meet the folks over there had me volunteering as a mechanic for a few months before my schedules changed. It was in remarkably good mechanical condition but it was clearly 37 years old and perhaps not serviced in much of that time. So full teardown, clean, lubricate, new consumables etc. It would have been quick and simple except for personal injury, oh, and a hidden broken axle that was hard to source a replacement.  I say 'hidden' because if I hadn't taken it apart, I probably wouldn't have known and had probably been ridden for some time based on the way it was stuck in. The break was so clean, right at the bearing that at first it looked like a re...
