Economically priced electronic group set from China - Wheeltop

Wheels of Happiness

Its 50% of the price of Shimano or  SRAM.  Experts say that the abandonment by SRAM of the mechanical GS market.

The price at Lazada is P29,000+ for rim brakes and P34,000 for the first time user.  The regular price is  700 pounds or Php 49,000.

The parts are made of carbon fiber

I might be tempted to try out the electonic group set  (My s works configuration makes it difficult to stick to cabled gs)

Good experience so far

SRAM red sti failed in this morning ride

Wheels of Happiness

This post experienced failure on this am ride intended to go around Teresa.  I could only shift to the 5th cog and no more  up ot Mambog.  So this post decided to return because that meant I could not negotiate steep hills at Teresa and Antipolo because the shifter was not working properly.

Could it be failure of the shifting mechannism inside STI?  Did the pawls or the plastic dram fail.

Five km from Mamabog on the way beck this post tried to examine the tightness of shift cable.  And lo and behold, it was.  The cable was loose by at least 4-5 mm.   I tightened the cable, (pulled by hand and later with a plier when I reached home) and tightened the nut the cable nut well.  And the problem seemed to have been resolved

Cables and uts do get loose and they result in such function failures   Be sure to bring tools

Thought I have to see Mario Toledo again or worse buy a new shifter.   Good for me.  Savings

Shimano Ultegra 6700 shifter repair/rebuild

Wheels of Happiness

I used to have these shifters:    6700 and 6800.   I never had difficulty with these shifters.  But this is a guide in case something turns out bad.  It turns out with ridgid training one can do this.  One needs good memory and good spatial logic

Do not try this.  Let the mechanic do this repair.

Repair of sram Red shifter. I only spent P800..00 for this with Mario

Wheels of Happiness

I encountered the same problem with the same problem with my SRAM red shifter.  The drum cylinder where the head of the cable shifter was inserted.  The outer lip shattered and the cable head would not get installed_  it would slip.

The solutions available were :   buy a new shifter, or get a new nylon drum cylinder.  But it SRAM does not support its old shifter with parts.   There was one available at Bike Inn which would set me back by $500.00 (same at Ebay)   We paid all ready but Bike inn notified that it ran out of stock. 

So I ran out of solution.   Just buy the new SRAM 22, or wait for SRAM shifter at the Marketplace.   

I brought this to Mario and he came up with a brilliant solution.  He plastic welded the drum nylon cylinder.  SOLVED.  Only for P800.00.  It could have been P25,000.!!

(I let him do this because the other problem I had was threading the internal cable at the internal cabling system -  it is too much of a hassle)

Repair of my Campy Ergo Shifter

 The Fuji Bike with brand new Clark bar tape; it is expensive

      
During the Bisikleta Iglesia last Maundy  Thursday, I brought the Fuji bike with Campy group set.  VM, the former owner of the Campy and the frame, and the Cosmic wheelset, saw something was amiss in the bike:  the shifter.  There were wires protuding from the shifter.

He suggested that I had it looked into and repaired.  He had problem before with his Campy and it was stuck and the Christy mechanic spent almost an hour having it unstuck.  He went to Christy last Saturday with Ven to buy a Mavic wheelset.  So I lost the opportunity to have it inspected and repaired soon.
