    POC Spin helmet & life expectancy

    i have two (2) - one dated manufacture spring 2020, the other fall 2019. the '20 gel cushion has opened in one place, prompting me to investigate their mfg dates. i can buy aftermarket cushions on Big A. Q: is it time to toss the helmets & get new? neither have been crashed, but i've also...

    Raleigh 27" to - wheel conversion

    the thrust of changing wheels is two-fold. stock rims are un-hooked. 27" size is somewhat a challenge to fit with tires. yes; they are there and i was able to get Pasela gum walls, but it was more of an ordeal than i need in my life. perhaps both non-issues in the big picture, but i choose to...

    Raleigh 27" to - wheel conversion

    i don't have a camera, but don't understand what a picture would tell the numbers don't. brakes are centerpull "Raleigh" labeled but look diacompe to me.

    Raleigh 27" to - wheel conversion

    if you only knew what i went through sizing tires . . . how big is a 700s wheel/ tire (inch measurements) and 28 would correspond to an 1 1/8" width? the front (existing brake arms) have a bit more down travel available, but the the rears are maxed out now. i would not mind an unmatched set...

    Raleigh 27" to - wheel conversion

    Raleigh 1983 Record Special mixte. starting down the rabbit hole. existing factory steel rims have no hooks for tire wire. if i am changing rims, i want to go aluminum and a size smaller for the addition of fenders. i will need long reach brakes. back wheel is now solid axle; want to change to...

    Daniel Rebour - Illustrator. Who's your favourite cycling illustrator/Cartoonist?

    years ago (around 2010ish)i would read each magazine cover to cover. at on point i even had all the back issues. in the past 5 or 6 years, i read maybe 10 pages and then give the magazine to my barber for his table of old Newsweek, Atlantic Monthly, and Popular Science for guys to thumb through...

    tube size confusion

    thanks for the information & chuckle. i get most of what you explained but don't know about these alleged "blocks" of which you speak: "...as long as there's (630-622/2) 4mm drop available on the blocks." space between the top & bottom of the rim hook to capture the tyre wire? in my defense, i...

    tube size confusion

    i agree; kind of got some bad vibrations when working on them. since this is not going to be my daily driver bike, i'm probably going to swap them out and at the same time turn the rear axle into a skewered/ quick release (solid w/ nuts now). as this goes together, it will only be a 3-5 mile...

    tube size confusion

    combined with my overzealousness to get the tyres & tubes switched over, i think this is where i zigged when i should have zagged. the Araya rims are of the hookless variety, and i was evidently less observant than i should have been. i inflated the tubes/ types to about 55#, bounced them...

    tube size confusion

    well . . . you fellows must be clairvoyant. my first tube/ tire swap came with a similar bang. when it got to 80# (sidewall indicates required 95#) i noticed the tire bead becoming exposed more than usual. as i began to unscrew the pump head, i thought i heard a hiss and then POW! tube split...

    tube size confusion

    if this tube is 27.5, how does it get rated 630? the box indicates 28" - and is only adding to my confusion. i am assuming it does Not have the weight of the "marathon" line of puncture resistant tubes - which are heavier than i need. thanks ps: i just ordered (2 + spare) the SV16 tubes w/...

    kind of sort of; by my word the range of sizes completely baffles me.
