Spotted this cheap Columbus Foco aero tubed frameset on eBay and was going to post it here but stuck an offer on that was accepted.

I'm going to inquire next week about the history with the original shop in Cambridgeshire but might anyone here know anything about them or who builder might be?

Frame now sold - sorry!

Price drop. Estimate postage will probably about £25-30?

Thanks both, looking at a couple or hubs with options that have a 20h rears - would that be a terrible idea?

At least 16g saved 👍

Would a 16h front be okay for a HC/race only wheel?

Presumably 16h will be fine for lightweights if the rim is strong enough and can take high tension? The rim I'm looking at has an upper limit of 180kgf.

Thought they might be proprietary, shame as the hubs seem great...

2nd dibs if that offer falls through and if you can post.

I've thought about picking up a worn pair of c24s on eBay for exactly this purpose but didn't know if the hub required proprietary spokes. Will any regular straight pull spoke work with them?

Fwiw you can get 16h carbon rims from Lightbicycle.

Think there's a couple of GB coaches there too tonight. GL!

Giros now sold, many thanks. Price drop chainring.

Can I ask for some opinions on rim width choice for use solely on indoor velodromes? Rims will probably be mid depth (55-65) open mould/Chinese rims from farsport/lightbicycle/etc.

My head says 23mm 'narrow' due to the low yaw angles experienced on the track and a couple of people I sought advice from have also said 23mm. However there is also the advice that rims should be wider (1.05x) than the tyre which will probably be a 23mm Pista Speed.

Campag 3/32" 56t - just got some DA cranks, very good condition, no signs of wear. £25 posted.
Trevano 3/32" 55t - have some wear but still plenty usable. £15 posted

Lezyne Road Drive Medium - some wear to outer barrel but fully working. £10 posted

Cheers both, was thinking about selling them on and wanted to be sure what they actually were. Now they've been serviced though and they're working nicely again I might keep them around!

Just realised that these Sram Force calipers I bought last year have a very slightly different finish to one another (one has a darker titanium style finish, the other has a more silver finish) - has one spent more time in the sun and faded or are they different versions/eras of Force?

New Dolan fleet at Manchester, haven't seen these GXP style Alpina cranks before but look to be good value at £99 inc chainring and BB.

Will dig through my electronics box and see what I can find. Cheers

What's the name for this plastic part on the caliper spring and are replacements available anywhere?

*it's a brake spring guide according to Shimno apparently...

Ah, thanks once again tester. I hadn't realised that tech doc was one of their usual exploded diagrams!

Think I'll return it then, I heard some people at Manchester use either the 7700 or the cheaper 105 version with the seals removed.

Does anyone know what the differences are between the Shimano Dura-Ace BB-7710 'Track' and the 'Road' BB-7700? Does the 7710 have the same needle and ball bearing internals the same as the bb-7700?

I purchased a bb-7700 'without seals' and a 7710 has turned up.

Decided to sell my Argos frameset made from Columbus Gara tubing, 55cm ctc, 55cm tt.

Selling as a frame and forks, complete with headset, seatpost and seatpost bolt.

Paint is pretty tatty with plenty of chips but the frame has been internally sprayed with a framesaver type oil. Steerer is cut pretty short but is fine with a low stack headset.

Any questions, please ask.

Thinking of getting some Chinese deep carbon tubular rims to build up shortly for indoor track use only but not sure what width to choose.

Given that 19mm Pista Evos are no longer manufactured is it best to go for wider 25mm rims for wider 23mm Pista Speed tyres or are 23mm wide rims still the ones to go for with these tyres? Or should I get the 23mm rims and stock up on 19mm tubs?

Thanks, those could be worth a shot.
