Not as much rant

Last evening I took the chair out for a spin now that I have the extensions installed and as much tweaking as I can do for positioning ... and turned in 2.8 miles in 19 minutes. That's a damned good time for me - not near what I want to be, but still very respectable.

BUT, it could be better:

1. I could tell that I could have gotten more power into my cranking IF I could have lowered the Bottom Bracket another 2 or 3 inches (you want the centerline to be about the level of your lower sternum for the highest efficiency). That can't happen without more clearance - and that won't happen with the current crank arms.

2. I could feel the flex in the crank arms under maximum load - that is NOT a good thing! I'm really afraid the arms are going to fail - probably during a race when I really need them the most.

Current options:

1. Keep using the current setup until the point of failure and then have to raise money to replace the crank arm system;

2. Start a fund raiser to replace the necessary parts to upgrade to a wider crank arm system now;

3. Try to get a sponsor so I can get the really nice things - such as racing wheels, better cassette (10 speed to go with a SRAM DD-3 hub), better crankset and disc brakes. You have to set high goals ;)

Duh!

My leased handcycle was from New Hampshire. My new handcycle was built for use in Florida. Do you think it might be geared just a little differently? DUH!



Let's just say that inclines are MUCH more challenging! In spite of the gearing difference, A quick 2 mile training run went real well. 17 minutes with an average speed of 6.9 mph and a max of 13.5 on mostly flat road with a several small (33 foot climb) rolling hills. That would be close to a PR for a 5K distance ... in street clothes!

Looks like it's time to consider getting the SRAM Dual Drive hub. Specifically the DD3-30 with Disc Brakes.


That would give me an extra low range, a 1:1 direct drive and a high end boost for going down any hills I have to climb. It would also change out the 9 speed cassette for a 10 speed cassette giving me an even lower granny low.

Because of the on going move, it won't happen "soon", but it WILL happen.
