Re: tub rims for a track bike

Re: tub rims for a track bike

so i'd ride the wheels on roads on warm dry days using a front brake (as little as possible.) then clean the tubs up and use them on an indoor track. got a set of open pros/miche wheels for the bike already. wanted to use the pair of hubs and i'm a traditional type of guy....sooo thought i'd give tu...

tub rims for a track bike

i've got a pair of decent ish track hubs sitting in the shed doing not so much. the plan is to build them up into a lightweight pair of outdoor track wheels.

so...tub rims....talk to me :)

(running the front one with a brake 50% of the time.)

Re: Il Pompino discontinued ! Why & how long ago ?

£750 for that genesis bike?! i wouldn't want a carbon fork for a winter commuter. pompinos are decent frames, not light, but not bad. didn't PX scale down the company a few years ago? i wouldn't be surprised if they no longer have the bank facilities to order large amounts of frames to be shipped to...

Re: Anyone ever tempted by a cheap bike?

as mentioned in another thread in the late 90s i got cheesed off keeping gears clean for every day riding and invested about £250 in a nearly new SJS fixed bike from a friend who didn't like it. rode it to work, rode it in the hills for training when i raced, really hammered it miles wise. it's now ...

Re: Di2 - A technology too far?

I commute with my bike with di2 for more than 40km/day, 6 days a week, 12 months a year in all weather. Not once have I had any problems with the Di2 and not once has the battery failed. I charge the battery once a month. Since I've had the bike, I've never had to have the di2 serviced/set, and gea...

Re: Schwalbe Marathon 700 x 38C matching folding spare?

yes 622 is the size of a tyre to fit on a 700c rim.

a clincher is a 'normal' tyre. the type you use with an inner tube.

(as opposed to a 'tubular' which is glued to a different style of rim. these are a traditional type of racing tyre.)

Re: A technology too far?

A friend with hand flexibility and strength issues, bought a new bike with Di2 and hydraulic discs. She can now ride 50 miles without hand pain. So in this case Di2 and hydros are like raising your bars and putting on lower gears. So to update... “Variable gears and electronic shifting are only for...

Re: A technology too far?

i always see kit like this to be akin to F1 type technology in that field. some gizmo that makes the car corner half a degree flatter and saws off 0.003 secs per lap. hence it can be argued that it has a use as the gear change is 'X' better in circumstance 'Y.' it isn't going to get legions more bum...

Re: Deep Rim/Short Spokes vs. Shallow Rim/Long Spokes

i'd be at least as concerned about tyre choice. just wouldn't fancy a quick lossy puncture when ripping downhill at 50+mph. but does that mean new tyres? or something newish with a few hundred miles on them to scrub off the outer surfaces. FWIW i'd go with shallow rims for the wind cheating effects ...

Re: Titanium seatpost that is all titanium

I have a Chinese one that I think is all Ti. The clamp most certainly is very very tough, so not a cheaply alloy. Bolts were Ti and crap. Thanks, do you have a name for it or a link? Try xacd.com . I have a titanium frame from them, purchased in 2005. Still in good nick. They do titanium seat posts...
