View Full Version : Pasela TG and bottle dynamo?

Rebuilding my cross for the coming summers tour and I am now choosing tires. I like the Pasela TG 35mm but I also plan to use a bottle dynamo. Has anyone tried this combination? I fear that the thin sidewalls of the Paselas cannot take the bottle dynamo. I plan to go pretty fast, light so I am not too keen on putting heavy marathons on the bike but I am open for suggestions.

Don't do it (the Paselas). I've not had very good luck with them. Not great on flat prevention and weak sidewalls. OTOH, I rode with 6 guys, just finishing up the Southern Tier, all with Marathon +s. Between the 6, they had 2 flats over the entire tour. Go with the Marathon+. A little weight means nothing when you're constantly repairing flats--not to mention the hazard of weak sidewalls.

P.S. I've have 2 or 3 brand new Paselas I'd be happy to provide at a wonderful discount. P.M. me if you're interested.

you want a tire with a dynamo chafing strip. I bet Panaracer even makes one. Vittorias?

Batteries. Lights these days are really bright and use less power. I met a guy that had a blinking tail light powered by magnets on his wheel, but generators are a drag. When I tried to use one, it cut into my tire. That was twenty years ago. I hate batteries, but LED lights use so little power...

Yeah I figured that Marathon would be the way to go. Regarding dynamo I really like my lightspin and I find the drag to be minimal compared to the reliability. Works like a charm even in heavy rain. I guess snow would kill it though.

I asked this very question (about dynamo strips) on rec.bicycles.tech yesterday:

http://groups.google.com/group/rec.bicycles.tech... (http://groups.google.com/group/rec.bicycles.tech/browse_frm/thread/55f846ea5230719e/2b35e2c5d0240970#)

If you are not familiar with him, Andy Muzi is a well-respected bike mechanic. I consider him to be the closest thing the cycling community now has to a Sheldon Brown-type guru.

I'm running Panaracer CTX-737 tires. They do have a dynamo strip. I never have any slippage in wet conditions but being in the southeast usa I've never had any snow to deal with. You can almost see the strip in the photo below.

I built my own LED headlight. I used two SCC P4 Z-power LED's with Fraen lenses. One is a 15X30 degree producing an elliptical pattern and the other is a narrow 10 degree beam. Both produce a very nice extremely bright pattern. Fancy driver circuits are not required. A dynamo is limited to about 500mA. The latest High power LED's can handle 1A so a dynamo will only drive them at half rated power. There still very bright at half current. I have cagers flash there high beams at me in an attempt to get me to dim my light. I built and used an MR-16 20-watt halogen light and battery for commuting once. My dynamo and homebuilt LED light illuminates the road just as well. Dynamo headlights and circuits can be found here.
