You'll probably want to clean off the old glue--though it probably will crack off.David Yang said:I'm building up a track back next week and using the old set of wheels with the ancient tubulars from 1986 still glued onto them.
- After I take the old ones off, do I have to clean the inside of the rim?
- Glue or tape?
- What new tires do you recommend that don't cost $100+ each?
glue over tape. A good glue job is faster.
Tires are hard. If this is for Kissena's track, 23mm at least, if not 25mm. Go to biketechreview.com to look at Al Morrison's chart and then start searching for deals on the fast tires.
Kieran might have some good tire suggestions.

The original spec for the rim was 25mm tires, but these nice tires on sale only come in 23s!

edit: Got the above tires anyway. If they don't fit the rim, so be it.

Have any of you ridden the Turbo, Specialized's e-bike? umm...holy crap. Possibly the most fun joyriding experience I've ever had. We have a couple in the shop and I just got back from testing one. Two, three pedal strokes and you're doing 20mph. A little dodgy in traffic, but that's part of the fun!

OK, Fabian.

i saw joaquin today and he said his legs seemed tired. i can only guess that they felt tired because he, like so many of you, has not slept since i indicated that my seat was creaking. rest easy, my friends, for i have found the solution.
the creak was the seat and the rails. not the seatpost, not the screws in the seatpost. i took the seat off of my girlfriend's caad10 (it has the female version of my seat, a prologo kappa, stock caad10 seat) and put it on my own seatpost. the creaking is gone. now there is only the painful, silent indifference of a seat that doesn't care for my anatomy.
as i pedal along in beautiful silence, one thought comes to my mind and also to my chamois:

I had the same problem with my prologo scratch pro that came with my caad10. Where the rail met the saddle creaked and creaked to no end after a year of riding. I couldn't fix it so I bought a new saddle.

So I got a great deal on a 53/39 crankset, so I can upgrade from my compact and both go more fasterer and suffer more sufferer... Is this a swap I can do at home? Do I need a new chain? I've swapped fixed cranks before but am thinking this is a different animal...
Jun 25, 2013 at 10:16 PM
@Dave, you might be able to do it on your own if you have the tools.
theres a bit you arent mentioning about your set up but you will def need a longer chain and you will probably have to adjust your front derailleur as it will no longer be the same distance from the big chain ring.

Dave,
I can guide you through the swap. PM me. If you're in Brooklyn its easier.

Thanks guys-- i'd figured as much about the chain, no problem on that. @ragot, i'm definitely in brooklyn, will be in touch once its in my clutches. thank you!
it's a caad10 bb30; fsa going off, fsa coming on.
Cheers!

I need to buy some Shimano spokes. Anyone know a dealer of them here in the US?
Jun 26, 2013 at 07:44 PM
Anybody have a favorite "how to glue a tubular" resource online?

what kind of tubie? Road or CX?
I think that following the glue manufacturer's instructions works fine

Jun 26, 2013 at 08:56 PM
that's a great deal. only $499 to save you the bother or rotating your eyeballs downwards.

Hincapie is their spokesmodel. His heads up display apparently includes real time hematocrit.

get part number from shimano's manuals (http://techdocs.shimano.com/) and order through LBS?Adam said:I need to buy some Shimano spokes. Anyone know a dealer of them here in the US?
*awaits beat-down response from adam who asked a specific question to which brendan provided a nonresponsive answer*
Jun 27, 2013 at 12:24 AM
@Shimano spokes: did you try Google. I don't do shimano, but I might suggest loose screws or Sheldon brown. I might suggest Brantford Bike, but they are campy centric.
Jun 27, 2013 at 01:59 AM
Over the winter, I tested out some chains to see if I could detect the frictional difference between the two.
Red Kite Prayer has the experiment up. in two parts
Jun 27, 2013 at 03:06 PM
@Brendan - you did all the work for me, I will not chide you further for providing an answer for a question you made up.
@dstokes - yep, tried Google, just comes up with UK suppliers! Not sure why UK cyclists are after Shimano replacement parts more frequently than US ones. Must be all that SRAM drivel floating about, don't need to replace a part as your component is still under SRAM warranty as you only bought it 4 months ago.
I have ordered some from a UK supplier. I know the part number as I am familiar with the way this works (Shimano tech docs are fantastic, IKEA should hire that little dude in Japan who makes them, would help). Problem is, getting them from the UK is a pain in the ass. Sometimes comes in 2 days, sometimes 2 weeks. Can never tell. I need them ASAP, hence thought I could just order them stateside. I'm just waiting at the moment but don't mind getting extra as they're $3 each, and you can never have too many spokes.

i fixed my creaking saddle! applied lubricant to the foam/cloth that interfaces w/ the plastic skeleton. progold ftw! the creaking was coming from the dried out cloth rubbing against the plastic. perhaps bicycle lubricant, a harsh chemical, is not the ideal liquid to rehydrate the cloth/foam saddle and it will disintegrate. but at least it will die quietly.

i recently bought an 11-28 105 cassette to switch out my 11-23 force (for hilly rides, etc).
should the switch be as simple as whipping off the force and replacing it with the 105? or will it end like pretty much most of my DIY bike repairs: simple on paper but a nightmare in execution?

@Mark - It's simple on paper and in practice.
Jul 01, 2013 at 02:40 PM
@Clifford, make sure your chain has enough links to accommodate the bigger rear cog. Also, current chain might be too worn and muck up your shifting. Otherwise, it's just popping the old cogs on/off. If your new cassette came packaged retail it might come with a plastic retainer piece to keep it organized. I like to use those to hold the old cassette (a long zip tie or twine is also good to use).
Otherwise since you're sticking with 11t, no new lockring needed or anything.

thanks jeff / yang. chain is pretty new -- two months of use in it.
awesome. i'll be able to climb thursday at an rpm higher than 50.

Mark,
you might also want to adjust the angle of your rear derailleur so that the upper pulley can get low enough to be under the 28. For most derailleurs, this screw pushes against the stop on the derailleur hanger.
Jul 01, 2013 at 10:56 PM
Are Mtn bike bottom brackets just as fu*ked as road BB's or is there (gasp) compatibility?
Jul 01, 2013 at 11:18 PM
I can go from a 23 to a 29 without adjusting my rear derailleur...so try shifting and go online for signs to look for if your derailleur needs adjusting.
Jul 01, 2013 at 11:53 PM
I have two things to say.
1) just try it
2) you don't need a 28 unless you follow Ryan up the Malibu hills
